Answer:

-4 : -32

-3 : 0

-2 : 14

-1 : 16

0 : 12

Step-by-step explanation:

To get your answers, all you need to do is input the value of w that you are given into the equation of w^3 - 5w + 12.

An example of this, using the first value given:

Begin with w^3 - 5w + 12 and input the value -4 to make -4^3 - 5(-4) + 12

Simplify and solve the first parts of the equation,

    -4^3 = -64 & 5(-4) = -20

This will give you -64 - (-20) + 12 / -64 + 20 + 12

Solve through by starting with -64 + 20 = -44, then -44 + 12 = -32.

All you need to do is continue the process with each value, for example the -2 value would make the equation -2^3 - 5(-2) + 12

-2^3 = -8 & 5(-2) = -10

-8 - (-10)  + 12 = -8 + 10 + 12

-8 + 10 = 2  --> 2 + 12 = 14

To find the formula for the nth partial sum and determine if the series converges or diverges, we are given a series of the form Σ(α^n)/(6^(n+1)) and need to evaluate it.

The answer involves finding the formula for the nth partial sum, applying the convergence test, and determining the sum of the series if it converges.

The given series is Σ(α^n)/(6^(n+1)), where α is a constant. To find the formula for the nth partial sum, we need to compute the sum of the first n terms of the series.

By using the formula for the sum of a geometric series, we can express the nth partial sum as Sn = (a(1 - r^n))/(1 - r), where a is the first term and r is the common ratio.

In this case, the first term is α/6^2 and the common ratio is α/6. Therefore, the nth partial sum formula becomes Sn = (α/6^2)(1 - (α/6)^n)/(1 - α/6).

To determine if the series converges or diverges, we need to examine the value of the common ratio α/6. If |α/6| < 1, then the series converges; otherwise, it diverges.

Finally, if the series converges, we can find its sum by taking the limit of the nth partial sum as n approaches infinity. The sum of the series will be the limit of Sn as n approaches infinity, which can be evaluated using the formula obtained earlier.

By applying these steps, we can determine the formula for the nth partial sum, assess whether the series converges or diverges, and find the sum of the series if it converges.

The standard deviation of the sampling distribution of X, the number of people in an SRS of size 50 that would vote for the incumbent governor, is approximately 3.52. This means that if many samples of size 50 were taken from the population, the number of people who would respond that they would vote for the incumbent would typically vary by about 3.52 from the mean of 23.

The standard deviation of the sampling distribution of X can be calculated using the formula [tex]\sqrt{p(1-p)/n}[/tex], where p is the proportion of the population that would vote for the incumbent (0.46 in this case) and n is the sample size (50 in this case). Plugging in these values, we get sqrt(0.46(1-0.46)/50) ≈ 0.0715.

The standard deviation represents the average amount of variation or spread we would expect to see in the sampling distribution of X. In this case, it tells us that if we were to take many samples of size 50 from the population, the number of people who would respond that they would vote for the incumbent would typically vary by about 3.52 (0.0715 multiplied by the square root of 50) from the mean of 23 (0.46 multiplied by 50).

Therefore, the correct statement is: If you were to take many samples of size 50 from the population, the number of people who would respond that they would vote for the incumbent would typically vary by about 3.52 from the mean of 23.

23) [tex]\int\limits x^{4} \sqrt{x^{5} +10} dx[/tex]

Simplify the integral by using a substitution.

Let's substitute [tex]u = x^5 + 10[/tex], then [tex]du = 5x^4 dx.[/tex]

The integral becomes:

[tex]\int\limits (1/5) \sqrt{u} du[/tex]

Now we can integrate u^(1/2) with respect to u:

[tex]\int\limits (1/5) \sqrt{u} du[/tex] = [tex](2/15) u^{3/2} + C[/tex]

Substituting back [tex]u = x^5 + 10[/tex], we get:

[tex](2/15) (x^5 + 10)^{3/2} + C[/tex]

Therefore, the integral of [tex]x^4 \sqrt{(x^5 + 10)}dx[/tex] is [tex](2/15) (x^5 + 10)^{3/2} + C[/tex].

24) [tex]\int\limits \frac{(ln x)^{3}}{x} dx[/tex]

We can use integration by parts to solve this integral. Let's choose [tex]u = (ln x)^3[/tex] and dv = dx.

Then [tex]du = 3(ln x)^2 (1/x) dx[/tex] and v = x.

Applying the integration by parts formula:

[tex]\int\limits \frac{(ln x)^{3}}{x} dx[/tex] = [tex]u * v - \int\limits v * du \\ = (ln x)^3 * x - \int\limits x * 3(ln x)^2 (1/x) dx \\ = (ln x)^3 * x - 3 \int\limits (ln x)^2 dx[/tex]

Let's choose [tex]u = (ln x)^2[/tex] and [tex]dv = dx[/tex].

Then [tex]du = 2(ln x)(1/x) dx[/tex] and v = x.

[tex]\int\limits \frac{(ln x)^{3}}{x} dx[/tex] = [tex](ln x)^3 * x - 3 [(ln x)^2 * x - 2 \int\limits (ln x)(1/x) dx] \\ = (ln x)^3 * x - 3 (ln x)^2 * x + 6 \int\limits (ln x)(1/x) dx[/tex]

The remaining integral can be solved as:

[tex]6 \int\limits (ln x)(1/x) dx = 6 \int\limits ln x dx \\ = 6 (x(ln x) - x) + C[/tex]

Substituting this back into the previous expression:

[tex]\int\limits (ln x)^3 / x dx = (ln x)^3 * x - 3 (ln x)^2 * x + 6 (x(ln x) - x) + C[/tex]

Simplifying further, we get:

[tex]\int\limits (ln x)^3 / x dx = (ln x)^3 * x - 3 (ln x)^2 * x + 6x(ln x) - 6x + C[/tex]

Therefore, the integral of [tex](ln x)^3 * x - 3 (ln x)^2 * x + 6x(ln x) - 6x + C[/tex].

The area of the region bounded by the function f(x), the Z-axis, and the vertical lines x = 2 and x = 3 are approximately XX square units.

To find the area of the region, we need to integrate the absolute value of the function f(x) over the given interval. Since f(x) is negative on (2, 3) and positive on (3, 4), we can split the integral into two parts.

First, we integrate the absolute value of f(x) over the interval (2, 3). The integral of f(x) over this interval will give us the negative area. Next, we integrate the absolute value of f(x) over the interval (3, 4), which will give us the positive area.

The function f(x) is concave up on the interval (0, +∞) and concave down on the interval (-∞, 0).

a) to determine the intervals over which the function f(x) = x³ - 4x'' is concave up or concave down, we need to analyze its second derivative, f''(x).

first, let's find the first and second derivatives of f(x):f'(x) = 3x² - 4

f''(x) = 6x

to find the intervals of concavity, we examine the sign of the second derivative.

for f''(x) = 6x, the sign depends on the value of x:- if x > 0, then f''(x) > 0, meaning the function is concave up.

- if x < 0, then f''(x) < 0, meaning the function is concave down. b) inflection points occur where the concavity changes. to find the inflection points, we need to determine where the second derivative changes sign or where f''(x) = 0.

setting f''(x) = 0:6x = 0

the equation above has a solution at x = 0. so, x = 0 is a potential inflection point.

to confirm if it is indeed an inflection point, we examine the concavity of the function on both sides of x = 0. since the concavity changes from concave up to concave down, x = 0 is indeed an inflection point.

The statement that cannot be made about n = 0 is "K can be any value on the interval."

To understand why this statement cannot be made, let's analyze the given information. We know that the limit of the integral b lim (g(x) dx) as n approaches infinity is equal to K, where K is a specific value in the interval [0, 10000]. Additionally, g(x) is a continuous and positive decreasing function.

The fact that g(x) is a continuous and positive decreasing function implies that it approaches a finite limit as x approaches infinity. This means that as x increases, the values of g(x) become smaller and eventually stabilize around a certain value.

Now, when we consider the limit of the integral b lim (g(x) dx) as n approaches infinity, it represents the accumulation of the function g(x) over an increasing interval. As n becomes larger and larger, the interval over which we integrate g(x) expands.

Since g(x) is a decreasing function, the integral b lim (g(x) dx) will also approach a finite limit as n approaches infinity. This limit is the value K mentioned in the question. It represents the total accumulation of the function g(x) over the infinite interval.

However, it is important to note that as n approaches 0 (the lower limit of integration), the interval over which we integrate g(x) becomes smaller and smaller. This means that the value of the integral will be affected by the behavior of g(x) near x = 0.

Given that g(x) is a continuous and positive decreasing function, we can make certain observations about its behavior near x = 0. For example, we can say that g(x) approaches a finite positive value as x approaches 0. However, we cannot make any specific statements about the exact value of the integral at n = 0. It could be any value within the interval [0, K].

In summary, while we can make general statements about the behavior of g(x) and the limit of the integral as n approaches infinity, we cannot determine the exact value of the integral at n = 0. Therefore, the statement "K can be any value on the interval" cannot be made about n = 0.

To find the degree 2 Taylor polynomial for the function ƒ(x) = (3x + 9) (3/2) centered at a = 0, we need to find the polynomial that approximates the function using the values of the function and its derivatives at x = 0.

First, let's find the first few derivatives of ƒ(x)[tex]: ƒ(x) = (3x + 9)^(3/2) ƒ'(x) = (3/2)(3x + 9)^(1/2) * 3 ƒ''(x) = (3/2)(1/2)(3x + 9)^(-1/2) * 3 = (9/2)(3x + 9)^(-1/2)[/tex]

Now, let's evaluate these derivatives at x = 0[tex]: ƒ(0) = (3(0) + 9)^(3/2) = 9^(3/2) = 27 ƒ'(0) = (9/2)(3(0) + 9)^(-1/2) = (9/2)(9)^(-1/2) = (9/2) * (3/√9) = 9/2 ƒ''(0) = (9/2)(3(0) + 9)^(-1/2) = (9/2)(9)^(-1/2) = (9/2) * (3/√9) = 9/2[/tex]

Now we can write the degree 2 Taylor polynomial, T₂(x), using these values: T₂(x) = ƒ(0) + ƒ'(0)x + (ƒ''(0)/2!)x² = 27 + (9/2)x + (9/2)(1/2)x² = 27 + (9/2)x + (9/4)x²

Therefore, the degree 2 Taylor polynomial for the function ƒ(x) = [tex](3x + 9)^(3/2)[/tex]centered at a = 0 is T₂(x) = 27 + (9/2)x + (9/4)x².   The Taylor series expansion for f(x) is given by[tex]:f(x) = Σ (fⁿ(a) / n!) * (x - a)^n[/tex], where fⁿ(a) represents the nth derivative of f evaluated at a.

The length of the curve defined by x = [tex]cos^2(t)[/tex] and y = cos(t) as t varies from 0 to 5π is 10 units.

To find the length of the curve, we use the arc length formula for parametric curves:

L = ∫[a,b] √[[tex](dx/dt)^2 + (dy/dt)^2[/tex]] dt

In this case, we have x = [tex]cos^2(t)[/tex] and y = cos(t). Let's calculate the derivatives dx/dt and dy/dt:

dx/dt = -2cos(t)sin(t)

dy/dt = -sin(t)

Now, we substitute these derivatives into the arc length formula:

L = ∫[0,5π] √[[tex](-2cos(t)sin(t))^2 + (-sin(t))^2[/tex]] dt

Simplifying the expression inside the square root:

L = ∫[0,5π] √[tex][4cos^2(t)sin^2(t) + sin^2(t)][/tex] dt

= ∫[0,5π] √[[tex]sin^2[/tex](t)([tex]4cos^2[/tex](t) + 1)] dt

Applying a trigonometric identity [tex]sin^2(t)[/tex] + [tex]cos^2(t)[/tex] = 1:

L = ∫[0,5π] √[1([tex]4cos^2(t)[/tex] + 1)] dt

= ∫[0,5π] √[[tex]4cos^2(t)[/tex] + 1] dt

We can notice that the integrand √[[tex]4cos^2(t)[/tex] + 1] is constant. Thus, integrating it over the interval [0,5π] simply yields the integrand multiplied by the length of the interval:

L = √[[tex]4cos^2(t) + 1[/tex]] * (5π - 0)

Maximum value: √15 + 1/8

Minimum value: -√15 + 1/8

To find the maximum and minimum values of the function f(x, y) = 2x + y on the ellipse x^2 + 4y^2 = 1, we can use the method of Lagrange multipliers.

First, let's define the objective function:

F(x, y) = 2x + y

And the constraint function:

g(x, y) = x^2 + 4y^2 - 1

We need to find the critical points where the gradient of the objective function is parallel to the gradient of the constraint function:

∇F(x, y) = λ∇g(x, y)

Taking the partial derivatives:

∂F/∂x = 2

∂F/∂y = 1

∂g/∂x = 2x

∂g/∂y = 8y

Setting up the equations:

2 = λ(2x)

1 = λ(8y)

x^2 + 4y^2 = 1

From the first equation, we have two possibilities:

λ = 1 and 2x = 2x (which is always true)

λ = 0 (but this case does not satisfy the second equation)

For λ = 1, we can solve the second equation:

1 = 8y

y = 1/8

Substituting this value into the third equation:

x^2 + 4(1/8)^2 = 1

x^2 + 1/16 = 1

x^2 = 15/16

x = ±√(15/16) = ±√15/4 = ±√15/2

Therefore, we have two critical points:

P1: (x1, y1) = (√15/2, 1/8)

P2: (x2, y2) = (-√15/2, 1/8)

Now, we need to evaluate the function f(x, y) = 2x + y at these critical points and compare them to the function values on the boundary of the ellipse.

Boundary of the ellipse:

x^2 + 4y^2 = 1

We can solve for x in terms of y:

x^2 = 1 - 4y^2

x = ±√(1 - 4y^2)

Substituting this into the objective function:

f(x, y) = 2x + y

f(x, y) = 2(±√(1 - 4y^2)) + y

We want to find the maximum and minimum values of f(x, y) on the ellipse, so we need to evaluate f(x, y) at the critical points and at the boundary points.

Let's calculate the values:

At the critical point P1: (x1, y1) = (√15/2, 1/8)

f(x1, y1) = 2(√15/2) + 1/8

= √15 + 1/8

At the critical point P2: (x2, y2) = (-√15/2, 1/8)

f(x2, y2) = 2(-√15/2) + 1/8

= -√15 + 1/8

On the boundary:

We need to find the maximum and minimum values of f(x, y) on the ellipse x^2 + 4y^2 = 1.

Substituting x = √(1 - 4y^2) into f(x, y):

f(x, y) = 2(√(1 - 4y^2)) + y

Now we have a one-variable function:

f(y) = 2√(1 - 4y^2) + y

To find the maximum and minimum values of f(y), we can take the derivative with respect to y and solve for y when the derivative equals zero:

f'(y) = 0

2(-8y)/2√(1 - 4y^2) + 1 = 0

-8y = -1√(1 - 4y^2)

64y^2 = 1 - 4y^2

68y^2 = 1

y^2 = 1/68

y = ±√(1/68) = ±1/(2√17)

Substituting these values into f(y):

f(±1/(2√17)) = 2√(1 - 4(±1/(2√17))^2) ± 1/(2√17)

= 2√(1 - 4/68) ± 1/(2√17)

= 2√(17/17 - 4/68) ± 1/(2√17)

= 2√(13/17) ± 1/(2√17)

= √221/17 ± 1/(2√17)

The surface of the solid is bounded by Calculate the cylinder y² + 2² = 4 and the planes is 24π.  Option a is the correct answer.

To calculate the surface integral, we'll use the divergence theorem as mentioned earlier. The divergence of the vector field F is given by:

div(F) = (3y²) + (e²) + (3z²)

Now, we need to evaluate the triple integral of the divergence of F over the volume enclosed by the solid.

The solid is bounded by the cylinder y² + z² = 4 and the planes x = 0 and x = 1. This represents a cylindrical region extending from x = 0 to x = 1, with a radius of 2 in the y-z plane.

Using cylindrical coordinates, we have:

x = ρcos(θ)

y = ρsin(θ)

z = z

The limits of integration are:

ρ: 0 to 2

θ: 0 to 2π

z: -2 to 2

The volume element in cylindrical coordinates is: dV = ρdzdρdθ

Now, we can write the triple integral as follows:

∭ div(F) dV = ∫∫∫ (3y² + e² + 3z²) ρdzdρdθ

Performing the integration, we get:

∫∫∫ (3y² + e² + 3z²) ρdzdρdθ

= ∫₀² ∫₀² ∫₋²² (3(ρsin(θ))² + e² + 3z²) ρdzdρdθ

Simplifying the integrand further:

= ∫₀² ∫₀² ∫₋²² (3ρ²sin²(θ) + e² + 3z²) ρdzdρdθ

Now, let's evaluate the triple integral using these limits and the simplified integrand:

∫₀² ∫₀² ∫₋²² (3ρ²sin²(θ) + e² + 3z²) ρdzdρdθ

= 24π

Therefore, the result of the surface integral is 24π. The correct option is option a.

F(x) is increasing on the interval (0, +∞) and decreasing on the interval (-∞, 0).

to determine where the function f(x) = 1 - 1/x is increasing or decreasing, we need to analyze its derivative, f'(x).

a) increasing and decreasing intervals:we can find the derivative of f(x) by applying the power rule and the chain rule:

f'(x) = -(-1/x²) = 1/x²

to determine the intervals where f(x) is increasing or decreasing, we examine the sign of the derivative.

for f'(x) = 1/x², the derivative is positive (greater than zero) for x > 0, and it is negative (less than zero) for x < 0. b) local extrema:

to find the local extrema of f(x), we need to identify the critical points. these occur where the derivative is either zero or undefined.

setting f'(x) = 0:

1/x² = 0

the above equation has no real solutions, so there are no critical points.

since there are no critical points, there are no local extrema for the function f(x) = 1 - 1/x.

in summary:a) f(x) is increasing on the interval (0, +∞) and decreasing on the interval (-∞, 0).

b) there are no local extrema for the function f(x) = 1 - 1/x.

Two variable quantities a and b are found to be related by the equation. Therefore, the rate of change at the moment when A= 5 and dB/dt = 3 is -0.36.

Given A³ + B³ = 152At the given moment A= 5 and dB/dt = 3, we are required to find the rate of change.

To find the rate of change we use implicit differentiation, that is differentiating both sides of the equation with respect to time (t).

Differentiating A³ + B³ = 152 with respect to time, we get: 3A²(dA/dt) + 3B²(dB/dt) = 0

Using the given values A= 5 and dB/dt = 3, substituting in the equation, we get: 3(5)²(dA/dt) + 3B²(3) = 0

Simplifying we get, 75(dA/dt) + 9B² = 0

Since we don't have the value of B, we need to express B in terms of A.To do that, we differentiate A³ + B³ = 152 with respect to A.

3A² + 3B² (dB/dA) = 0dB/dA = -(3A²)/(3B²)dB/dA = -(A²)/(B²)

Now we can replace B with the given values of A and the equation, we get: dB/dt = dB/dA * dA/dt3 = -(A²)/(B²) * dA/dtAt A = 5,

we have, 3 = -(5²)/(B²) * dA/dt(5²)/(B²) * dA/dt = -3dA/dt = -(3*B²)/(5²) = -0.36

Answer:

a) The domain of f(x) is all real numbers since there are no restrictions or conditions given in the function.

b) The domain of g(x) is all real numbers except for x = 1 since the function h(x) has a term of (x - 1) in the denominator, which cannot be equal to zero.

c) To find (fog)(x), we substitute the function g(x) = 2x - 7 into f(x) and simplify.

Step-by-step explanation:

a) The function f(x) = -3 is defined for all real numbers. Therefore, the domain of f(x) is (-∞, ∞) in interval notation.

b) The function g(x) is given by g(x) = 2x - 7. The only restriction in the domain occurs when the denominator of h(x) is zero. Since h(x) = (x - 1)² - 9, we set the denominator equal to zero and solve for x:

(x - 1)² - 9 = 0

(x - 1)² = 9

x - 1 = ±√9

x - 1 = ±3

x = 1 ± 3

x = 4 or x = -2

Therefore, the domain of g(x) is (-∞, -2) ∪ (-2, 4) ∪ (4, ∞) in interval notation.

c) To find (fog)(x), we substitute g(x) into f(x):

(fog)(x) = f(g(x)) = f(2x - 7)

Using the definition of f(x) = -3, we have:

(fog)(x) = -3

Therefore, (fog)(x) simplifies to -3 for any input x.

In summary:

a) The domain of f(x) is (-∞, ∞).

b) The domain of g(x) is (-∞, -2) ∪ (-2, 4) ∪ (4, ∞).

True . In this distribution, the mean salary is lower than the median salary because the few employees who earn a very high salary pull the mean towards the left.

In a left-skewed distribution, the tail of the distribution is longer on the left-hand side, which means that there are more values on the left side of the distribution that are lower than the mean. This pulls the mean towards the left, making it lower than the median. Therefore, the median tends to be higher than the mean in a left-skewed distribution.

When we talk about the shape of a distribution, we refer to the way in which the values are spread out across the range of the variable. A left-skewed distribution is one in which the tail of the distribution is longer on the left-hand side, which means that there are more values on the left side of the distribution that are lower than the mean. The mean is the sum of all values divided by the number of values, while the median is the middle value of the distribution. In a left-skewed distribution, the mean is pulled towards the left, making it lower than the median. This happens because the more extreme values on the left side of the distribution have a larger impact on the mean than they do on the median.

The solutions in the interval [0,2π) are x = 0, π, and arctan(2/3).This gives us sin(x) + (1 - sin^2(x)) - 1 = c(*).

To solve the equation sin(x) + cos*(x) - 1 = c(), we can simplify it by rewriting cos(x) as 1 - sin^2(x), using the Pythagorean identity.

This gives us sin(x) + (1 - sin^2(x)) - 1 = c(*).

Simplifying further, we have -sin^2(x) + sin(x) = 0.

Factoring out sin(x), we get sin(x)(-sin(x) + 1) = 0.

This equation is satisfied when sin(x) = 0 or -sin(x) + 1 = 0.

In the interval [0,2π), sin(x) = 0 at x = 0, π, and 2π. For -sin(x) + 1 = 0, we have sin(x) = 1, which occurs at x = π/2.

Therefore, the solutions in the given interval are x = 0, π/2, and 2π.

The equation sin(x) + V2 = -sin(x) can be simplified by combining like terms, resulting in 2sin(x) + V2 = 0.

Dividing both sides by 2, we have sin(x) = -V2. In the interval [0,2π), sin(x) is negative in the third and fourth quadrants.  

Taking the inverse sine of -V2, we find that the principal solution is x = 7π/4.  However, since we are restricting the interval to [0,2π), the solution is x = 7π/4 - 2π = 3π/4.

The equation 3tan*(x) - 1 - 0 ) sin(x) cos(x) - cox(x) - 2 cot(x) tan(x) + sin(x) can be simplified using trigonometric identities. Rearranging the terms, we have 3tan^2(x) - sin(x) + cos(x) - 2cot(x)tan(x) + sin(x)cos(x) = 1.

Simplifying further, we get 3tan^2(x) - 2tan(x) + 1 = 1.This equation reduces to 3tan^2(x) - 2tan(x) = 0. Factoring out tan(x), we have tan(x)(3tan(x) - 2) = 0. This equation is satisfied when tan(x) = 0 or 3tan(x) - 2 = 0.

In the given interval, tan(x) = 0 at x = 0 and π. Solving 3tan(x) - 2 = 0, we find tan(x) = 2/3, which occurs at x = arctan(2/3). Therefore, the solutions in the interval [0,2π) are x = 0, π, and arctan(2/3).
