3. The absolute maximum value of f(x) = -12x + 1 on the interval [1, 3] is -11, and the absolute minimum value is -35.
2. Find the equation of the tangent line to the curve: [tex]y = x^2+ 2[/tex] at the point (1, 1).
To find the equation of the tangent line, we need to determine the slope of the tangent line at the given point and use it to form the equation.
Given point:
P = (1, 1)
Step 1: Find the derivative of the curve
dy/dx = 2x
Step 2: Evaluate the derivative at the given point
m = dy/dx at x = 1
m = 2(1) = 2
Step 3: Form the equation of the tangent line using the point-slope form
[tex]y - y_1 = m(x - x_1)y - 1 = 2(x - 1)y - 1 = 2x - 2y = 2x - 1[/tex]
3. Find the absolute maximum and absolute minimum values of f(x) = -12x + 1 on the interval [1, 3].
To find the absolute maximum and minimum values, we need to evaluate the function at the critical points and endpoints within the given interval.
Given function:
f(x) = -12x + 1
Step 1: Find the critical points by taking the derivative and setting it to zero
f'(x) = -12
Set f'(x) = 0 and solve for x:
-12 = 0
Since the derivative is a constant and does not depend on x, there are no critical points within the interval [1, 3].
Step 2: Evaluate the function at the endpoints and critical points
f(1) = -12(1) + 1 = -12 + 1 = -11
f(3) = -12(3) + 1 = -36 + 1 = -35
Step 3: Determine the absolute maximum and minimum values
The absolute maximum value is the largest value obtained within the interval, which is -11 at x = 1.
The absolute minimum value is the smallest value obtained within the interval, which is -35 at x = 3.

Morgan and Donna are cabinet makers. When working alone, it takes Morgan 8 more hours than Donna to make one cabinet. Together, they make one cabinet in 3 hours. Find how long it takes Morgan to make one cabinet by herself.
For Morgan to make one cabinet by alone, it will take 12 hours.
Representing the problem MathematicallyAssuming Donna takes "x" hours to make one cabinet.
Morgan takes 8 more hours
Then , Donna = "x + 8" hours to make one cabinet.
Working together , time taken = 3 hours.
We can set up an equation based on their rates of work:
1/(x + 8) + 1/x = 1/3
(1 * x + 1 * (x + 8)) / ((x + 8) * x) = 1/3
(x + x + 8) / (x² + 8x) = 1/3
(2x + 8) / (x² + 8x) = 1/3
3(2x + 8) = x² + 8x
6x + 24 = x² + 8x
Rearranging the equation:
x² + 2x - 24 = 0
Now we can factor or use the quadratic formula to solve for "x." Factoring the equation:
(x + 6)(x - 4) = 0
x + 6 = 0 or x - 4 = 0
x = -6 or x = 4
Since we are considering time, the solution cannot be negative. Therefore, x = 4, which means it takes Donna 4 hours to make one cabinet.
Morgan's time = 4 + 8 = 12 hours
Therefore, it takes Morgan 12 hours to make one cabinet by herself.

N = Vg(X, y, 2) at (3,2, 1). (ii) Find the symmetric equation of the line I through (3, 2, 1) in the direction N; find
also the canonical equation of the plane through (3, 2, 1) that is normal to M.
N = Vg(X, y, 2) at the normal vector N at (3, 2, 1) is (2, 3, 6) . The symmetric equation of the line I passing through (3, 2, 1) in the direction of N is x - 3/2 = y - 2/3 = z - 1/6. The canonical equation of the plane through (3, 2, 1) is 2x + 3y + 6z = 20.
The function g(X, Y, 2) is equal to xyz - 6. By substituting X = 3, Y = 2, and Z = 1, we find that g(3, 2, 1) = 0. The normal vector N of the function at (3, 2, 1) is (2, 3, 6). The symmetric equation of the line I passing through (3, 2, 1) in the direction of N is x - 3/2 = y - 2/3 = z - 1/6. The canonical equation of the plane through (3, 2, 1) that is normal to M is 2x + 3y + 6z = 20. Given the function g(X, Y, 2) = xyz - 6, we can substitute X = 3, Y = 2, and Z = 1 to find g(3, 2, 1). Plugging in these values gives us 3 * 2 * 1 - 6 = 0. Therefore, g(3, 2, 1) equals 0.
To find the normal vector N at (3, 2, 1), we take the partial derivatives of g with respect to each variable: ∂g/∂X = YZ, ∂g/∂Y = XZ, and ∂g/∂Z = XY. Substituting X = 3, Y = 2, and Z = 1, we obtain ∂g/∂X = 2, ∂g/∂Y = 3, and ∂g/∂Z = 6. Therefore, the normal vector N at (3, 2, 1) is (2, 3, 6). The symmetric equation of a line passing through a point (3, 2, 1) in the direction of the normal vector N can be written as follows: x - 3/2 = y - 2/3 = z - 1/6.
To find the canonical equation of the plane through (3, 2, 1) that is normal to the normal vector N, we use the point-normal form of a plane equation: N · (P - P0) = 0, where N is the normal vector, P is a point on the plane, and P0 is the given point (3, 2, 1). Substituting the values, we have 2(x - 3) + 3(y - 2) + 6(z - 1) = 0, which simplifies to 2x + 3y + 6z = 20. This is the canonical equation of the desired plane.

The given integral is ∫∫D (x+y²)dA, where D is the region in the first quadrant bounded by the lines y = 1 and y = √3x and the circle x²+y² = 9.
To find the special solutions for the given differential equation, we can solve it using the method of separation of variables. The differential equation is:
dy/dx = ( (x+y² / √(9 - x² - y²))))
To solve this, we can rewrite the equation as:
(1 + y²) dy = (x+y² / √(9 - x² - y²)) dx
Now, let's integrate both sides. First, we integrate the left side with respect to y:
∫(1 + y²) dy = ∫(x / √(9 - x² - y²)) dx
Integrating the left side gives:
y + (y³ / 3) = ∫(x / (9 - x² - y²)) dx
Next, we integrate the right side with respect to x. To do that, we need to consider y as a constant:
∫(x / √(9 - x² - y²)) dx
To evaluate this integral, we can use a substitution. Let's substitute u = 9 - x² - y². Then, du = -2x dx, which implies dx = -(du / (2x)). Substituting these into the integral:
∫(-(du / (2x))) = ∫(-du / (2x)) = -(1/2)∫(du / x) = -(1/2) ln|x| + C
Bringing it all together, we have:
y + (y³ / 3) = -(1/2) ln|x| + C
This is the general solution to the given differential equation. However, we are interested in finding special solutions for the given region D in the first quadrant.
The region D is bounded by the lines y = 1 and y = √(3x), as well as the circle x² + y² = 9.
To find the particular solution within this region, we can use the initial condition or boundary condition.
Let's consider the point (x₀, y₀) = (3, √3) within the region D. Plugging these values into the equation, we can solve for the constant C:
√3 + (3/3) (√3)³ = -(1/2) ln|3| + C
√3 + (√3)³ = -(1/2) ln|3| + C
Simplifying, we find:
2√3 + 3√3 = -(1/2) ln|3| + C
5√3 = -(1/2) ln|3| + C
C = 5√3 + (1/2) ln|3|
Therefore, the particular solution for the given differential equation within the region D is:
y + (y³ / 3) = -(1/2) ln|x| + 5√3 + (1/2) ln|3|

To evaluate the iterated integral, we'll integrate the given expression over the specified limits. The given integral is:
∫∫∫[0 to y] [0 to 2y] [0 to 1] xy dz dx dy
Let's evaluate this integral step by step.
First, we integrate with respect to z:
∫[0 to y] [0 to 2y] [0 to 1] xy dz = xy[z] evaluated from z=0 to z=y
= xy(y - 0)
= xy^2
Next, we integrate the expression xy^2 with respect to x:
∫[0 to 2y] xy^2 dx = (1/2)xy^2[x] evaluated from x=0 to x=2y
= (1/2)xy^2(2y - 0)
= xy^3
Finally, we integrate the resulting expression xy^3 with respect to y:
∫[0 to y] xy^3 dy = (1/4)x[y^4] evaluated from y=0 to y=y
= (1/4)x(y^4 - 0)
= (1/4)xy^4
Now, let's evaluate the overall iterated integral:
∫∫∫[0 to y] [0 to 2y] [0 to 1] xy dz dx dy

Using the trapezoidal rule with n = 3, we can approximate the integral of the function f(x) = √(√(√(4 + x^4))) over the interval [0, √3].
The trapezoidal rule is a numerical method for approximating definite integrals. It approximates the integral by dividing the interval into subintervals and treating each subinterval as a trapezoid.
Given n = 3, we have four points in total, including the endpoints. The width of each subinterval, h, is (√3 - 0) / 3 = √3 / 3.
We can now apply the trapezoidal rule formula:
Approximate integral ≈ (h/2) * [f(a) + 2∑(k=1 to n-1) f(a + kh) + f(b)],
where a and b are the endpoints of the interval.
Plugging in the values:
Approximate integral ≈ (√3 / 6) * [f(0) + 2(f(√3/3) + f(2√3/3)) + f(√3)],
≈ (√3 / 6) * [√√√4 + 2(√√√4 + (√3/3)^4) + √√√4 + (√3)^4].

To determine the value of f(6.9) accurate to four decimal places in the equation f(x): (x - 7)^n = 0, we need to calculate the first term of the series expansion. The result is approximately -0.3333.
In the equation f(x): (x - 7)^n = 0, it appears that the term (x - 7)^n is raised to the power of n, but the value of n is not provided. We can assume that n is a positive integer. To calculate f(6.9) accurately, we need to find the first term of the series expansion of (x - 7)^n. The series expansion of (x - 7)^n can be expressed as a polynomial of the form a_0 + a_1(x - 7) + a_2(x - 7)^2 + ... where a_0, a_1, a_2, ... are the coefficients. However, without knowing the value of n, we cannot determine the exact series expansion. Therefore, we cannot find the exact value of f(6.9).

The function f(c) is increasing on the interval (-∞, -4) and (3, ∞).The function f(x) is decreasing on the interval (-4, 3). The function f(x) has local maxima at x = -4 and local minima at x = 3.
To determine the intervals where the function is increasing, we need to examine the sign of the derivative. The given derivative represents the slope of the function. We observe that the derivative is positive when x < -4 and x > 3, indicating an increasing function. Therefore, the intervals where the function f(c) is increasing are (-∞, -4) and (3, ∞).
Similarly, we analyze the sign of the derivative to identify the intervals where the function is decreasing. The derivative is negative when -4 < x < 3, indicating a decreasing function. Thus, the interval where f(x) is decreasing is (-4, 3).
To find the local extrema, we examine the critical points by setting the derivative equal to zero. Solving the equation, we find two critical points: x = -4 and x = 3. We evaluate the sign of the derivative around these points to determine the nature of the extrema. Before x = -4, the derivative is negative, and after x = -4, it is positive, indicating a local minimum at x = -4. Before x = 3, the derivative is positive, and after x = 3, it is negative, indicating a local maximum at x = 3.

Find the antiderivative F(x) of the function f(x) (Use C for the constant of the antiderivative:) f(x) = 2 csc(x) cot(*) sec(x) tan(x) F(x)
the antiderivative of the function f(x) = 2 csc(x) cot(x) sec(x) tan(x) is F(x) = 2x + C.
To find the antiderivative F(x) of the function f(x) = 2 csc(x) cot(x) sec(x) tan(x), we can simplify the expression and integrate each term individually.
We know that csc(x) = 1/sin(x), cot(x) = 1/tan(x), sec(x) = 1/cos(x), and tan(x) = sin(x)/cos(x).
Substituting these values into the expression:
f(x) = 2 * (1/sin(x)) * (1/tan(x)) * (1/cos(x)) * (sin(x)/cos(x))
= 2 * (1/sin(x)) * (1/(sin(x)/cos(x))) * (sin(x)/cos(x)) * (sin(x)/cos(x))
= 2 * (1/sin(x)) * (cos(x)/sin(x)) * (sin(x)/cos(x)) * (sin(x)/cos(x))

Consider the vector v=(2 -1 -3) in Rz. v belongs to Sp n{( 2 -10), (1 2 -3)}. - Select one: True False
The vector v = (2, -1, -3) does not belong to the span of the set {(2, -10), (1, 2, -3)} in R3.
To determine if v belongs to the span of the set {(2, -10), (1, 2, -3)}, we need to check if v can be expressed as a linear combination of the vectors in the set. In other words, we need to find scalars c1 and c2 such that v = c1(2, -10) + c2(1, 2, -3).
If we attempt to solve this equation, we get the following system of equations:
2c1 + c2 = 2
-10c1 + 2c2 = -1
-3c2 = -3
Solving this system, we find that there is no solution. Therefore, v cannot be expressed as a linear combination of the given vectors, indicating that v does not belong to the span of the set. Hence, the statement is false.

Use the price demand equation to find E(p)the elasticity of demand. x =f(p) =91 -0.2 ep E(p)= 0
The price elasticity of demand (E(p)) for the given price-demand equation can be determined as follows:
[tex]\[ E(p) = \frac{{dp}}{{dx}} \cdot \frac{{x}}{{p}} \][/tex]
Given the price-demand equation [tex]\( x = 91 - 0.2p \)[/tex], we can first differentiate it with respect to p to find [tex]\( \frac{{dx}}{{dp}} \)[/tex]:
[tex]\[ \frac{{dx}}{{dp}} = -0.2 \][/tex]
Next, we substitute the values of [tex]\( \frac{{dx}}{{dp}} \)[/tex] and x into the elasticity formula:
[tex]\[ E(p) = -0.2 \cdot \frac{{91 - 0.2p}}{{p}} \][/tex]
To find the price elasticity of demand when E(p) = 0 , we set the equation equal to zero and solve for p :
[tex]\[ -0.2 \cdot \frac{{91 - 0.2p}}{{p}} = 0 \][/tex]
Simplifying the equation, we get:
[tex]\[ 91 - 0.2p = 0 \][/tex]
Solving for p , we find:
[tex]\[ p = \frac{{91}}{{0.2}} = 455 \][/tex]
Therefore, when the price is equal to $455, the price elasticity of demand is zero.
In summary, the price elasticity of demand is zero when the price is $455, according to the given price-demand equation. This means that at this price, a change in price will not result in any significant change in the quantity demanded.

To show that F(x, y, z) = (y, x + e^y, ye^(y^2) + 1) is conservative, we need to verify if the partial derivatives satisfy the condition ∂F/∂y = ∂F/∂x.
To determine if F is conservative, we need to check if it satisfies the condition of being a gradient vector field. A vector field F = (F1, F2, F3) is conservative if and only if its components have continuous first partial derivatives and satisfy the condition ∂F1/∂y = ∂F2/∂x, ∂F1/∂z = ∂F3/∂x, and ∂F2/∂z = ∂F3/∂y.
Let's calculate the partial derivatives of F(x, y, z) with respect to x and y:
∂F1/∂x = 0
∂F1/∂y = 1
∂F2/∂x = 1
∂F2/∂y = e^y
∂F3/∂x = 0
∂F3/∂y = e^(y^2) + 2ye^(y^2)
Since ∂F1/∂y = ∂F2/∂x and ∂F3/∂x = ∂F3/∂y, the condition for F being conservative is satisfied.

2. [5] Let C be the curve parameterized by r(t) = (5, 3t, sin(2t)). Give parametric equations for the tangent line to the curve at the point (5,6, 0).
The parametric equations for the tangent line to the curve at the point (5, 6, 0) are:
x = 5
y = 6 + 3t
z = 2t
To find the parametric equations for the tangent line to the curve at the point (5, 6, 0), we need to find the derivative of the vector function r(t) and evaluate it at the given point.
The derivative of r(t) with respect to t gives us the tangent vector to the curve:
r'(t) = (0, 3, 2cos(2t))
To find the tangent vector at the point (5, 6, 0), we substitute t = 0 into the derivative:
r'(0) = (0, 3, 2cos(0)) = (0, 3, 2)
Now, we can write the parametric equations for the tangent line using the point-direction form:
x = 5 + at

Consider the following Fx) = 9 - y2 from x = 1 to x = 3; 4 subintervals (a) Approximate the area under the curve over the specified interval by using the indicated number of subintervals
The area under the curve of the function f(x) = 9 - y^2 over the interval x = 1 to x = 3 is approximately 11.75 square units
To approximate the area under the curve, we can use the method of Riemann sums. In this case, we divide the interval [1, 3] into four subintervals of equal width. The width of each subinterval is (3 - 1) / 4 = 0.5.
We can then evaluate the function at the endpoints of each subinterval and multiply the function value by the width of the subinterval. Adding up all these products gives us the approximate area under the curve.
For the first subinterval, when x = 1, the function value is f(1) = 9 - 1^2 = 8. For the second subinterval, when x = 1.5, the function value is f(1.5) = 9 - 1.5^2 = 6.75. Similarly, for the third and fourth subintervals, the function values are f(2) = 9 - 2^2 = 5 and f(2.5) = 9 - 2.5^2 = 3.75, respectively.
Multiplying each function value by the width of the subinterval (0.5) and summing them up, we get the approximate area under the curve as follows:
Area ≈ (0.5 × 8) + (0.5 × 6.75) + (0.5 × 5) + (0.5 × 3.75) = 4 + 3.375 + 2.5 + 1.875 = 11.75.
Therefore, the area under the curve of the function f(x) = 9 - y^2 from x = 1 to x = 3, approximated using four subintervals, is approximately 11.75 square units.

the line integral of the given curve C is 23/2.
To evaluate the line integral of the given curve C, we will compute the line integral along each segment of the curve separately and then add the results.
First, we consider the line segment from (0, 0) to (3, 0). Parametrize this segment as follows:
x(t) = t, y(t) = 0, for 0 ≤ t ≤ 3.
The differential path element is given by dx = dt and dy = 0. Substituting these values into the line integral expression, we have:
∫[C1] (xdx + (x - y)dy) = ∫[0,3] (t dt + (t - 0) (0) dy)
= ∫[0,3] t dt
= [t^2/2] evaluated from 0 to 3
= (3^2/2) - (0^2/2)
= 9/2.
Next, we consider the line segment from (3, 0) to (4, 2). Parametrize this segment as follows:
x(t) = 3 + t, y(t) = 2t, for 0 ≤ t ≤ 1.
The differential path element is given by dx = dt and dy = 2dt. Substituting these values into the line integral expression, we have:
∫[C2] (xdx + (x - y)dy) = ∫[0,1] ((3 + t) dt + ((3 + t) - 2t) (2dt))
= ∫[0,1] (3dt + t dt + (3 + t - 2t) (2dt))
= ∫[0,1] (3dt + t dt + (3 + t - 2t) (2dt))
= ∫[0,1] (3dt + t dt + (3 + t - 2t) (2dt))
= ∫[0,1] (7dt)
= [7t] evaluated from 0 to 1
= 7.
Finally, we add the results from the two line segments:
∫[C] (xdx + (x - y)dy) = ∫[C1] (xdx + (x - y)dy) + ∫[C2] (xdx + (x - y)dy)
= 9/2 + 7

To evaluate dy and Ay for the function f(x) = 641- - 9) at x = 4 and dx = -0.125, the value of dy is -9 multiplied by dx, resulting in dy = (-9) * (-0.125) = 1.125. Ay represents the rate of change of y with respect to x, and in this case derivations is, Ay = dy/dx = 1.125 / -0.125 = -9.
To assess dy and Ay for the given capability f(x) = 641-9, we want to track down the subsidiary of the capability and afterward substitute the given upsides of x and dx.
Taking the subsidiary of the capability f(x) = 641-9, we get:
f'(x) = - 9(641-10) * (641-1)' = - 9(641-10) * (- 1) = 9(641-10)
Presently, how about we substitute the upsides of x and dx into the subsidiary to track down dy:
dy = f'(x) * dx = 9(641-10) * (- 0.125) = - 9(641-10) * (- 0.125)
Improving on this articulation:
dy = 9(641-10) * (- 0.125) = - 9(641-10) * (- 0.125) = 9(641-10) * 0.125
Subsequently, dy = 9(641-10) * 0.125
Presently, how about we track down Ay by subbing the given worth of x into the first capability:
Ay = f(x) = f(4) = 641-(4-9) = 641-(- 5) = 641+5 = 646

The particular solution to the given equation y'' - 6y' + 11y - 6y = e^(2x)(3 + 10x) is y_p = (0 + 0.5x)e^(2x)(3 + 10x).
To find a particular solution to the given equation y'' - 6y' + 11y - 6y = e^(2x)(3 + 10x), we can use the method of undetermined coefficients.
First, we assume a particular solution of the form y_p = (A + Bx)e^(2x)(3 + 10x), where A and B are constants to be determined.
Taking the first and second derivatives of y_p:
y_p' = (2A + (A + Bx)(3 + 10x))e^(2x)
y_p'' = (4A + (2A + (A + Bx)(3 + 10x))(3 + 10x) + (A + Bx)(10))e^(2x)
Substituting these derivatives into the given equation, we have:
(4A + (2A + (A + Bx)(3 + 10x))(3 + 10x) + (A + Bx)(10))e^(2x) - 6((2A + (A + Bx)(3 + 10x))e^(2x)) + 11((A + Bx)e^(2x)(3 + 10x)) - 6(A + Bx)e^(2x) = e^(2x)(3 + 10x)
Expanding and simplifying the equation, we get:
(4A + 6A + 3A + 9B + 30Bx + 10Bx^2 + 10A + 30Ax + 100Ax^2) e^(2x) - (12A + 6B + 20Bx + 30Ax) e^(2x) + (33A + 110Ax + 11Bx + 110Bx^2) e^(2x) - (6A + 6Bx) e^(2x) = e^(2x)(3 + 10x)
Matching the coefficients of like terms on both sides of the equation, we have the following equations:
4A + 6A + 3A + 9B + 10A = 0 -> 13A + 9B = 0
12A + 6B = 0
33A + 110A + 11B = 3
6A = 0
Solving this system of equations, we find A = 0 and B = 0.5.

To find the net area covered by the function f(x) = (x + 1)² for the interval (-1,2], we must take the definite integral of the function on that interval.
To find the integral of the function, we must first expand it using the FOIL method, as follows:
f(x) = (x + 1)²f(x) = (x + 1)(x + 1)f(x) = x(x) + x(1) + 1(x) + 1(1)f(x) = x² + 2x + 1
Now that we have expanded the function, we can integrate it on the given interval as shown below:`∫(-1,2]f(x) dx = ∫(-1,2] (x² + 2x + 1) dx`
Evaluating the integral by using the power rule of integration gives:
∫(-1,2] (x² + 2x + 1) dx = [x³/3 + x² + x]
between -1 and 2`= [2³/3 + 2² + 2] - [(-1)³/3 + (-1)² - 1]`= [8/3 + 4 + 2] - [(-1/3) + 1 - 1]`= 14⅔

Sample size οf the secοnd sample (n₂) = 7
Sample variance οf the first sample (s₁²) = 100
Sample variance οf the secοnd sample (s₂²) = 20
Significance level (α) = 0.05

where s₁² is the sample variance οf the first sample and s₂² is the sample variance οf the secοnd sample.
Plugging in the given values:

Cοmparing the calculated F-value with the critical F-value:

Since the calculated F-value is greater than the critical F-value, we reject the null hypοthesis H0: σ₁² = σ₂².
Therefοre, we cοnclude that there is sufficient evidence tο suggest that the variances οf the twο pοpulatiοns are nοt equal.
