Rex claims that all functions have a domain of all real numbers. Which of the following graphs can be used to REFUTE this claim?

The first partial derivatives of w are: [tex]$$\frac{\partial w}{\partial x} = sin(xy) y$$$$\frac{\partial w}{\partial y} = sin(xy) x - cos(y)$$[/tex] for the given equation.

The given equation is [tex]cos(xy) + sin(y)[/tex]+ w = 81.

A key idea in multivariable calculus is partial derivatives. They entail maintaining all other variables fixed while calculating the rate at which a function changes with regard to a single variable. Using the symbol (), partial derivatives are calculated by taking the derivative of a function with regard to one particular variable while treating all other variables as constants.

They offer important details about how sensitive a function is to changes in particular variables. Partial derivatives are frequently used to model and analyse complicated systems with several variables and comprehend how changes in one variable affect the entire function in a variety of disciplines, including physics, economics, and engineering.

To find the first partial derivatives of w, we need to differentiate implicitly:

[tex]$$\begin{aligned}\frac{\partial}{\partial x} [cos(xy)] + \frac{\partial}{\partial x} [w] &= 0\\ -sin(xy) y + \frac{\partial w}{\partial x} &= 0\\ \frac{\partial w}{\partial x} &= sin(xy) y\end{aligned}$$Similarly,$$\begin{aligned}\frac{\partial}{\partial y} [cos(xy)] + \frac{\partial}{\partial y} [sin(y)] + \frac{\partial}{\partial y} [w] &= 0\\ -sin(xy) x + cos(y) + \frac{\partial w}{\partial y} &= 0\\ \frac{\partial w}{\partial y} &= sin(xy) x - cos(y)\end{aligned}$$[/tex]

Hence, the first partial derivatives of w are:[tex]$$\frac{\partial w}{\partial x} = sin(xy) y$$$$\frac{\partial w}{\partial y} = sin(xy) x - cos(y)$$[/tex]

For a factorable trinomial x² + bx + c, the absolute value of b can be less than, equal to, or greater than the absolute value of c, depending on the specific values of b and c.

The quadratic trinomial formula in one variable has the general form ax2 + bx + c, where a, b, and c are constant terms and none of them are zero.

For any factorable trinomial of the form x² + bx + c, the absolute value of b can sometimes be less than, equal to, or greater than the absolute value of c. The relationship between the absolute values of b and c depends on the specific values of b and c.

Let's consider a few cases:

1. If both b and c are positive or both negative: In this case, the absolute value of b can be less than, equal to, or greater than the absolute value of c. For example:

  - In the trinomial x² + 2x + 3, the absolute value of b (|2|) is less than the absolute value of c (|3|).

  - In the trinomial x² + 4x + 3, the absolute value of b (|4|) is greater than the absolute value of c (|3|).

  - In the trinomial x² + 3x + 3, the absolute value of b (|3|) is equal to the absolute value of c (|3|).

2. If b and c have opposite signs: In this case, the absolute value of b can also be less than, equal to, or greater than the absolute value of c. For example:

  - In the trinomial x² - 4x + 3, the absolute value of b (|4|) is greater than the absolute value of c (|3|).

  - In the trinomial x² - 2x + 3, the absolute value of b (|2|) is less than the absolute value of c (|3|).

  - In the trinomial x² - 3x + 3, the absolute value of b (|3|) is equal to the absolute value of c (|3|).

Therefore, for a factorable trinomial x² + bx + c, the absolute value of b can be less than, equal to, or greater than the absolute value of c, depending on the specific values of b and c.

Using the definition of derivative, f'(x) and f''(x) for the function f(x) = [tex]5x^2 - 6x + 3[/tex]are found to be f'(x) = 10x - 6 and f''(x) = 10.

To find the derivative f'(x) of the function f(x) = [tex]5x^2 - 6x + 3[/tex] using the definition of derivative, we need to apply the limit definition derivative:

f'(x) = lim(h -> 0) [f(x + h) - f(x)] / h

Substituting the function f(x) = 5x^2 - 6x + 3 into the definition, we get:

f'(x) = lim(h -> 0) [tex][(5(x + h)^2 - 6(x + h) + 3) - (5x^2 - 6x + 3)] / h[/tex]

Expanding and simplifying the expression, we have:

f'(x) = lim(h -> 0)[tex][10hx + 5h^2 - 6h] / h[/tex]

Canceling the h terms and taking the limit as h approaches 0, we get:

f'(x) = 10x - 6

Thus, f'(x) = 10x - 6 is the derivative of f(x) with respect to x.

To find the second derivative f''(x), we differentiate f'(x) with respect to x:

f''(x) = d/dx [10x - 6]

Differentiating a constant term gives us zero, and the derivative of 10x is simply 10.

The problem involves finding the value of A(x) for different values of x, where A(x) is defined as the integral of a function f(t) with respect to t.

The graph of the function has a half circle and straight line segments. Additionally, the derivative of A(x) is also to be calculated.

a) A(2) can be found by computing the integral of f(t) from 0 to 2. Since the graph of the function has a half circle, the value of A(2) will be half the area of this circle plus the area of the rectangular region bounded by the x-axis and the line connecting (2, f(2)) and (2, 0).

The value can be computed by using the formula for the area of a circle and the area of a rectangle.

b) A(4) can be computed similarly by finding the integral of f(t) from 0 to 4. Since the graph of the function has straight line segments, the value of A(4) will be the sum of the areas of the rectangular regions bounded by the x-axis and the lines connecting (0, f(0)), (2, f(2)), (4, f(4)), and (4, 0).

c) A(8) can be found by computing the integral of f(t) from 0 to 8. Since the graph of the function has both a half circle and straight line segments,

the value of A(8) will be the sum of the areas of the half circle and the rectangular regions bounded by the x-axis and the lines connecting (0, f(0)), (2, f(2)), (4, f(4)), (7, f(7)), and (8, f(8)).

The function f(t) is piecewise continuous on the interval 0 ≤ t < ∞. The graph consists of a linear segment from 0 to 1, followed by a linear segment from 1 to 2, and then a constant value of 0 for t ≥ 2. The Laplace transform of f(t) can be computed by applying the Laplace transform to each segment separately.

To sketch the graph of f(t), we first observe that f(t) is defined differently for three intervals: 0 ≤ t < 1, 1 ≤ t < 2, and t ≥ 2. In the first interval, f(t) is a linear function of t, starting from 0 and increasing at a constant rate of 1. In the second interval, f(t) is also a linear function, but it starts from 2 and decreases at a constant rate of 1. Finally, for t ≥ 2, f(t) is a constant function with a value of 0. Therefore, the graph of f(t) will consist of a line segment from 0 to 1, followed by a line segment from 1 to 2, and then a horizontal line at 0 for t ≥ 2.

Regarding continuity, f(t) is continuous within each interval where it is defined. However, there is a jump discontinuity at t = 1 because the value of f(t) changes abruptly from 1 to 2. Therefore, f(t) is not continuous at t = 1. However, it is still piecewise continuous on the interval 0 ≤ t < ∞ because it consists of continuous segments and the discontinuity occurs at a single point.

To compute the Laplace transform of f(t), we apply the Laplace transform to each segment separately. For the first segment, 0 ≤ t < 1, the Laplace transform of t is 1/s^2. For the second segment, 1 ≤ t < 2, the Laplace transform of 2 - t is 2/s - 1/s^2. Finally, for t ≥ 2, the Laplace transform of the constant 0 is simply 0. Therefore, the Laplace transform of f(t) is 1/s^2 + (2/s - 1/s^2) + 0, which simplifies to (2 - 1/s)/s^2.

The first four nonzero terms of the Taylor series for the given function centered at a is 13 ln2 + (13/2)(x-2) + (-13/8)(x-2)² + (13/24)(x-2)³.

What is the Taylor series?

A function's Taylor series or Taylor expansion is an infinite sum of terms represented in terms of the function's derivatives at a single point. Near this point, the function and the sum of its Taylor series are equivalent for most typical functions.

Here, we have

Given: f(x) = 13 lnx at a = 2

We have to find the first four nonzero terms of the Taylor series for the given function centered at a.

f(x) = 13 lnx

f(2) = 13 ln2

Now, we differentiate with respect to x and we get

f'(x) = 13/x,  f'(2) = 13/2

f"(x) = -13/x², f"(2) = -13/2² = -13/4

f"'(x) = 26/x³, f"'(2) = 26/8

Now, by the definition of the Taylor series at a = 2, we get

= 13 ln2 + (13/2)(x-2) + (-13/4)(x-2)²/2! + (26/8)(x-2)³/3!

= 13 ln2 + (13/2)(x-2) + (-13/8)(x-2)² + (13/24)(x-2)³

Hence, the first four nonzero terms of the Taylor series for the given function centered at a is 13 ln2 + (13/2)(x-2) + (-13/8)(x-2)² + (13/24)(x-2)³.

Option b is the correct answer, To check whether two arrays are equal, you should (b) use a loop to check if the values of each element in the arrays are equal. This method ensures that you compare the elements of the arrays individually, rather than checking for memory location or relying on search algorithms.

To check whether two arrays are equal, you should use option b, which is to use a loop to check if the values of each element in the arrays are equal. This is because the equality operator only checks if the arrays are stored in the same memory location, and not if their contents are the same. Using array decay to determine if the arrays are stored in the same memory location is not a valid approach, as array decay only refers to how arrays are passed to functions. Using a search algorithm to determine if each value in one array can be found in the other array is also not a valid approach, as this only checks if the values exist in both arrays, but not if the arrays are completely equal.

The sum of the given series, Σ(-1)^(29χλη) n! n = 0, is undefined.

To find the sum of the series Σ(-1)^(29χλη) n! n = 0, let's break it down step by step.

Step 1: Rewrite the series in a more recognizable form.

The given series Σ(-1)^(29χλη) n! n = 0 can be rewritten as Σ((-1)^n * (29χλη)^n) / n!, where n ranges from 0 to infinity.

Step 2: Apply the exponential property.

Using the exponential property, we can rewrite (29χλη)^n as (29^(nχλη)).

Step 3: Simplify the expression.

Now, we have Σ((-1)^n * (29^(nχλη))) / n!. We can rearrange the terms to separate the two parts of the series.

Σ((-1)^n / n! * 29^(nχλη))

Step 4: Evaluate the series.

To find the sum of the series, we need to evaluate each term and sum them up. Let's calculate the first few terms:

n = 0: (-1)^0 / 0! * 29^(0χλη) = 1

n = 1: (-1)^1 / 1! * 29^(1χλη) = -29

n = 2: (-1)^2 / 2! * 29^(2χλη) = 841/2

n = 3: (-1)^3 / 3! * 29^(3χλη) = -24389/6

n = 4: (-1)^4 / 4! * 29^(4χλη) = 707281/24

To evaluate the integral over the region S, which is part of the plane < + 4y + z = 10 in the first octant, we need to understand the boundaries and limits of integration. By analyzing the given plane equation and considering the first octant, we can determine the range of values for x, y, and z.

The given plane equation is < + 4y + z = 10. To evaluate the integral over the region S, we need to determine the boundaries for x, y, and z. Since we are working in the first octant, where x, y, and z are all positive, we can set up the following limits of integration:

For x: The limits for x depend on the intersection points of the plane with the x-axis. To find these points, we set y = 0 and z = 0 in the plane equation. This gives us x = 10 as one intersection point. The other intersection point can be found by setting x = 0, which gives us 4y + z = 10, leading to y = 10/4 = 2.5. Therefore, the limits for x are from 0 to 10.

For y: Since the plane equation does not have any restrictions on y, we can set the limits for y as 0 to 2.5.

For z: Similar to y, there are no restrictions on z in the plane equation. Hence, the limits for z can be set as 0 to infinity.

Now that we have determined the limits of integration for x, y, and z, we can set up the integral over the region S. The integral will involve the appropriate function f(x, y, z) to be evaluated. The specific form of the integral will depend on the context and the given function.

To determine the value of P(x) based on the given expression, we need to equate the integrand the expression and solve for P(x). By comparing the coefficients of the terms on both sides of the equation, we find that P(x) = x + 3.

Let's rewrite the given expression as an integral:

∫(2x^2 - x + 3) / P(x) dx + 5(2x^2 - 2x + 10x).

To find P(x), we compare the terms on both sides of the equation.

On the left side, we have ∫(2x^2 - x + 3) / P(x) dx + 5(2x^2 - 2x + 10x).

On the right side, we have x + 3.

By comparing the coefficients of the corresponding terms, we can equate them and solve for P(x).

For the x^2 term, we have 2x^2 = 5(2x^2), which implies 2x^2 = 10x^2. This equation is true for all x, so it does not provide any information about P(x).

For the x term, we have -x = -2x + 10x, which implies -x = 8x. Solving this equation gives x = 0, but this is not sufficient to determine P(x).

Finally, for the constant term, we have 3 = 5(-2) + 5(10), which simplifies to 3 = 50. Since this equation is not true, there is no solution for the constant term, and it does not provide any information about P(x).

Combining the information we obtained, we can conclude that the only term that provides meaningful information is the x term. From this, we determine that P(x) = x + 3.

Therefore, the value of P(x) is x + 3, which corresponds to option A.

False. The volume of the solid E cannot be determined to be exactly 116 based on the information provided. Further calculations or additional information would be needed to determine the precise volume of the solid E.

To determine the volume of the solid E, we need to find the limits of integration and set up the triple integral using the given information. The region in the xy-plane enclosed by y = 0, x = 3, and y = 3x forms a triangular region.
The equation of the plane, [tex]z = 4x + y[/tex], indicates that the solid E lies below this plane. To find the upper limit of z, we substitute the equation of the plane into it:
[tex]z = 4x + y = 4x + 3x = 7x[/tex].
So, the upper limit of z is 7x.
Next, we set up the triple integral to calculate the volume of the solid E:
[tex]∭E dV = ∭R (7x) dy dx[/tex].
Integrating with respect to y first, the limits of integration for y are 0 to 3x, and for x, it is from 0 to 3.
[tex]∭R (7x) dy dx = ∫[0,3] ∫[0,3x] (7x) dy dx[/tex].
Evaluating the integral, we get:
[tex]∫[0,3] ∫[0,3x] (7x) dy dx = ∫[0,3] 7xy |[0,3x] dx = ∫[0,3] (21x^2) dx = 21(x^3/3) |[0,3] = 21(3^3/3) - 21(0) = 189[/tex]

(b) The function is increasing on the interval (-∞, 0) and decreasing on the interval (-16384, ∞).

(a) To find the critical numbers of the function, we need to find the values of x where the derivative of f(x) is either zero or undefined.

Taking the derivative of [tex]f(x) = x^{1/7} + 4[/tex], we get [tex]f'(x) = (1/7)x^{-6/7}[/tex].

Setting f'(x) = 0, we find [tex]x^{-6/7} = 0[/tex]. This equation has no solutions since [tex]x^{-6/7}[/tex] is never equal to zero.

Next, we check for values of x where f'(x) is undefined. Since f'(x) involves a power of x, it is defined for all values of x except when x = 0.

Therefore, the critical numbers of the function [tex]f(x) = x^{1/7} + 4[/tex] are x = 0 and x = -16384.

(b) To determine the intervals on which the function is increasing or decreasing, we can analyze the sign of the derivative.

Since [tex]f'(x) = (1/7)x^{-6/7}[/tex], the derivative is positive when x > 0 and negative when x < 0.

This implies that the function [tex]f(x) = x^{1/7} + 4[/tex] is increasing on the interval (-∞, 0) and decreasing on the interval (-16384, ∞).

A 4 kg mass is suspended from a spring, causing it to stretch by 8 cm. The mass is also connected to a viscous damper, which applies a force of 3 N when the mass's velocity is 5 m/s.

When the mass is suspended from the spring, it causes the spring to stretch. According to Hooke's Law, the spring force is proportional to the displacement of the mass from its equilibrium position. Given that the mass stretches the spring by 8 cm, we can calculate the spring force.

The viscous damper exerts a force that is proportional to the velocity of the mass. In this case, when the velocity of the mass is 5 m/s, the damper applies a force of 3 N. The equation for the damping force can be used to determine the damping coefficient.

To find the equilibrium position, we need to balance the forces acting on the mass. At equilibrium, the net force on the mass is zero. This means that the spring force and the damping force must be equal in magnitude but opposite in direction.

By setting up the equations for the spring force and the damping force, we can solve for the equilibrium position. This position represents the point where the forces due to the spring and the damper cancel each other out, resulting in a stable position for the mass.

The correct answer is a) Osmotic pressure.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

Osmotic pressure is indeed a colligative property, which means it depends on the concentration of solute particles in a solution and not on the nature of the solute itself. Osmotic pressure is the pressure required to prevent the flow of solvent molecules into a solution through a semipermeable membrane.

On the other hand, options b), c), and d) are all colligative properties:

b) Elevation of a boiling point: Adding a non-volatile solute to a solvent increases the boiling point of the solution compared to the pure solvent.

c) Freezing point: Adding a non-volatile solute to a solvent decreases the freezing point of the solution compared to the pure solvent.

d) Depression in freezing point: Adding a solute to a solvent lowers the freezing point of the solvent, causing the solution to freeze at a lower temperature than the pure solvent.

First, we need to find the z-score for the lower limit of the range (41 million dollars):  z = (41 - 70) / 18 = -1.61
Next, we need to find the z-score for the upper limit of the range (99 million dollars): z = (99 - 70) / 18 = 1.61
We can now use a standard normal distribution table or a calculator to find the area under the curve between these two z-scores. The area between -1.61 and 1.61 is approximately 0.9044. This means that approximately 90.44% of utility companies earned revenue between 41 million and 99 million dollars.


To find the percentage of utility companies with revenue between 41 million and 99 million dollars, we can use the z-score formula and the standard normal distribution table. The z-score formula is: (X - mean) / standard deviation. First, we'll calculate the z-scores for both 41 million and 99 million dollars: Z1 = (41 million - 70 million) / 18 million = -29 / 18 ≈ -1.61
Z2 = (99 million - 70 million) / 18 million = 29 / 18 ≈ 1.61
Now, we'll look up the z-scores in the standard normal distribution table to find the corresponding percentage values.
For Z1 = -1.61, the table value is approximately 0.0537, or 5.37%.
For Z2 = 1.61, the table value is approximately 0.9463, or 94.63%.

Stokes' theorem states that the work done by a vector field F along a curve C can be calculated by evaluating the curl of F and taking the surface integral of the curl over a surface S bounded by C.

First, we find the curl of F: [tex]curl(F) = (∂F₃/∂y - ∂F₂/∂z, ∂F₁/∂z - ∂F₃/∂x, ∂F₂/∂x - ∂F₁/∂y) = (-1, -1, -1).[/tex]
Next, we find a surface S bounded by C. Since C lies on the intersection of the cylinder [tex]x^2 + z^2 = 1[/tex] and the plane[tex]2x + 3y + z = 6[/tex],we can choose the part of the cylinder that lies within the plane as our surface S.
The normal vector to the plane is n = (2, 3, 1). To ensure the surface S is oriented in the same direction as C (clockwise when viewed from the positive y-axis), we choose the opposite direction of the normal vector, -n = (-2, -3, -1).

Now, we can evaluate the surface integral using Stokes' theorem: ſc F · dr = ∬S curl(F) ·
The integral simplifies to -6 ∬S dS = -6 * Area(S).
The area of the surface S can be found by parametrizing it with cylindrical coordinates[tex]: x = cosθ, y = r, z = sinθ[/tex], where 0 ≤ θ ≤ 2π and 0 ≤ r ≤ 6 - 2cosθ - 3r.

We evaluate the integral over the surface using these parametric equations and obtain the area of S. Finally, we multiply the area by -6 to obtain the work done by F along C.

(A) The leading term of the polynomial is 4x⁴, (B) The limit of P(x) as x approaches infinity is infinity, and (C) The limit of P(x) as x approaches negative infinity is negative infinity.

The polynomial P(x) = 18 + 4x⁴ - 6x is given, and we need to determine the leading term and limits as x approaches positive and negative infinity.

Find the leading term of the polynomial

The leading term of a polynomial is the term with the highest power of x. In this case, the highest power is 4, so the leading term is 4x⁴.

Now, evaluate the limit as x approaches infinity

To find the limit of P(x) as x approaches infinity, we consider the term with the highest power of x, which is 4x⁴

As x becomes infinitely large, the 4x⁴ term dominates, and the limit of P(x) approaches positive infinity.

Evaluate the limit as x approaches negative infinity

To find the limit of P(x) as x approaches negative infinity, we again consider the term with the highest power of x, which is 4x⁴. As x becomes infinitely negative, the 4x⁴term dominates, and the limit of P(x) approaches negative infinity.

Answer:

M/_ 1 = 107°

Explanation:

since the angles are corresponding the angles on the right triangle would be as such:

43° 64° and ?

since we know each triangle has to equal to 180 we set us a simple equation

64° + 43° +?° = 180°

107° + ?° = 180°

?° = 180° -107°

?° = 73°

through that process we calculated what is the lower right angle of the triangle

now since its a straight line all straight lines are equal to 180° so once again we set it up to a simple equation

73° + ?° = 180°

?° = 180° -73°

?° = 107°

M= 107°

The marginal revenue, R'(x), is given by option (C): R'(x) = 95(3x-1/2-2x)(3+x3/2)². This option correctly represents the derivative of the total revenue function, R(x) = -190√x(3+x3/2).

To find the marginal revenue, we need to take the derivative of the total revenue function, R(x), with respect to x. The given total revenue function is R(x) = -190√x(3+x3/2).

Applying the power rule and the chain rule, we differentiate the function term by term. Let's break down the steps:

Differentiating -190√x:

The derivative of √x is (1/2)x^(-1/2), and multiplying by -190 gives -95x^(-1/2).

Differentiating (3+x3/2):

The derivative of 3 is 0, and the derivative of x^3/2 is (3/2)x^(1/2).

Combining the derivatives obtained from both terms, we get:

R'(x) = -95x^(-1/2)(3/2)x^(1/2) = -95(3/2)x^(1/2-1/2) = -95(3/2)x.

Simplifying further, we have:

R'(x) = -95(3/2)x = -95(3x/2) = -95(3x/2)(3+x^3/2)².

The integral ∫[ln(e^2-1) (x + 1) ln(x + 1)] dx evaluates to (x + 1) ln(x + 1) - (x + 1) + C, where C is the constant of integration.

To evaluate the integral, we can use the method of integration by parts. Let's choose u = ln(e^2-1) (x + 1) and dv = ln(x + 1) dx. Taking the derivatives and integrals, we have du = [ln(e^2-1) + 1] dx and v = (x + 1) ln(x + 1) - (x + 1).

Applying the integration by parts formula ∫u dv = uv - ∫v du, we get:

∫[ln(e^2-1) (x + 1) ln(x + 1)] dx = (x + 1) ln(x + 1) - (x + 1) - ∫[(x + 1) [ln(e^2-1) + 1] dx

Simplifying the expression inside the integral, we have:

∫[ln(e^2-1) (x + 1) ln(x + 1)] dx = (x + 1) ln(x + 1) - (x + 1) - ∫[(x + 1) ln(e^2-1)] dx - ∫(x + 1) dx

Integrating the last two terms, we obtain:

∫[(x + 1) ln(e^2-1)] dx = ln(e^2-1) ∫(x + 1) dx = ln(e^2-1) [(x^2/2 + x) + C1]

∫(x + 1) dx = (x^2/2 + x) + C2

Combining all the terms, we get:

∫[ln(e^2-1) (x + 1) ln(x + 1)] dx = (x + 1) ln(x + 1) - (x + 1) - ln(e^2-1) [(x^2/2 + x) + C1] - (x^2/2 + x) - C2

Simplifying further, we obtain the final answer:

∫[ln(e^2-1) (x + 1) ln(x + 1)] dx = (x + 1) ln(x + 1) - (x + 1) - ln(e^2-1) (x^2/2 + x) - ln(e^2-1) C1 - (x^2/2 + x) - C2

Therefore, the integral evaluates to (x + 1) ln(x + 1) - (x + 1) - ln(e^2-1) (x^2/2 + x) - ln(e^2-1) C1 - (x^2/2 + x) - C2 + C, where C is the constant of integration.

The map xn+1 = rxn/(1 + x^2_n), where 0, has fixed points at xn = 0 for all values of r, and additional fixed points at xn = ±√(1 - r) when r ≤ 1, requiring further analysis to determine the presence of periodic solutions or chaos.

To analyze the long-term behavior of the map xn+1 = rxn/(1 + x^2_n), where 0, we need to find the fixed points and classify them as a function of r.

Fixed points occur when xn+1 = xn, so we set rxn/(1 + x^2_n) = xn and solve for xn.

rxn = xn(1 + x^2_n)

rxn = xn + xn^3

xn(1 - r - xn^2) = 0

From this equation, we can see that there are two potential types of fixed points:

xn = 0

When xn = 0, the equation simplifies to 0(1 - r) = 0, which is always true regardless of the value of r. So, 0 is a fixed point for all values of r.

1 - r - xn^2 = 0

This equation represents a quadratic equation, and its solutions depend on the value of r. Let's solve it:

xn^2 = 1 - r

xn = ±√(1 - r)

For xn to be a real fixed point, 1 - r ≥ 0, which implies r ≤ 1.

If 1 - r = 0, then xn becomes ±√0 = 0, which is the same as the fixed point mentioned earlier.

If 1 - r > 0, then xn = ±√(1 - r) will be additional fixed points depending on the value of r.

So, summarizing the fixed points:

When r ≤ 1: There are two fixed points, xn = 0 and xn = ±√(1 - r).

When r > 1: There is only one fixed point, xn = 0.

Regarding periodic solutions and chaos, further analysis is required. The existence of periodic solutions or chaotic behavior depends on the stability and attractivity of the fixed points. Stability analysis involves examining the behavior of the map near each fixed point and analyzing the Jacobian matrix to determine stability characteristics.

The rectangle with dimensions 21 m by 21 m has the largest area among rectangles with a perimeter of 84 m.

To find the dimensions of a rectangle with a perimeter of 84 m that maximizes the area, we need to use the properties of rectangles.

Let's assume the length of the rectangle is l and the width is w.

The perimeter of a rectangle is given by the formula: 2l + 2w = P, where P is the perimeter.

In this case, the perimeter is given as 84 m, so we can write the equation as: 2l + 2w = 84.

To maximize the area, we need to find the dimensions that satisfy this equation and give the largest possible value for the area. The area of a rectangle is given by the formula: A = lw.

Now we can solve the perimeter equation for l: 2l = 84 - 2w, which simplifies to l = 42 - w.

Substituting this expression for l into the area equation, we get: A = (42 - w)w.

To maximize the area, we can find the critical points by taking the derivative of the area equation with respect to w and setting it equal to zero:

dA/dw = 42 - 2w = 0.

Solving this equation, we find w = 21.

Substituting this value of w back into the equation l = 42 - w, we get l = 42 - 21 = 21.

Therefore, the dimensions of the rectangle that maximize the area are l = 21 m and w = 21 m.

In summary, the dimensions of the rectangle are 21 m by 21 m, so the answer is A. 21, 21.
