The measure of ZAFD is 50 degrees.

Based on the given information:

ZCFE is congruent to ZCFA.

mZCFB = 68°.

mZEFD = 62°.

To find the measure of ZAFD, we can use the fact that angles in the same segment of a circle are equal.

Since ZCFE and ZCFA are congruent, angle ZCFE is equal to angle ZCFA.

Therefore, mZCFA = mZCFE.

Now, let's find the measure of angle ZCFE:

mZCFE = mZCFB + mZEFD (Angle Addition Postulate)

mZCFE = 68° + 62°

mZCFE = 130°

Since ZCFA is congruent to ZCFE, we can conclude that mZCFA is also equal to 130°.

Now, to find the measure of ZAFD, we need to consider the angles in the quadrilateral ZAFD.

The sum of the angles in a quadrilateral is always 360°.

mZAFD + mZAFB + mZBFD + mZBFA = 360°

We know that mZAFB and mZBFD are equal to 90° because they are right angles (angle AFB and angle BFD are right angles in the diagram).

Therefore, we can rewrite the equation as:

mZAFD + 90° + 90° + mZBFA = 360°

Simplifying:

mZAFD + 180° + mZBFA = 360°

Rearranging the equation:

mZAFD + mZBFA = 360° - 180°

mZAFD + mZBFA = 180°

We know that mZBFA is equal to mZCFA, which is 130°.

Substituting the known values into the equation:

mZAFD + 130° = 180°

Subtracting 130° from both sides:

mZAFD = 180° - 130°

mZAFD = 50°

Therefore, the measure of ZAFD is 50 degrees.

The steady-state response to the given input function is zero.

To find the steady-state response Yss to the given input function f(t), we need to apply the input to the transfer function and take the Laplace transform of both sides of the resulting equation. Then, we can find the value of Yss using the final value theorem.

In this case, the transfer function is T(s) = 3/(s+3) and the input function is f(t) = 9sin(2t+8.1).

Taking the Laplace transform of both sides, we get:

Y(s)/F(s) = T(s) = 3/(s+3)

Multiplying both sides by F(s), we get:

Y(s) = (3F(s))/(s+3)

Using the inverse Laplace transform, we get:

y(t) = 3e^(-3t)u(t) * f(t)

where u(t) is the unit step function.

To find the steady-state response Yss, we apply the final value theorem, which states that:

Yss = lim(t->∞) y(t)

Since the exponential term decays to zero as t goes to infinity, we can ignore it when taking the limit. Therefore:

Yss = lim(t->∞) 3u(t) * f(t)

Since the input function is periodic with period pi, the limit exists and is equal to the average value of the function over one period:

Yss = (1/pi) ∫(0 to pi) 3sin(2t+8.1) dt

Using trigonometric identities, we can simplify this to:

Yss = (3/pi) ∫(0 to pi) sin(2t)cos(8.1) + cos(2t)sin(8.1) dt

The integral of sin(2t)cos(8.1) over one period is zero, since the sine function is odd and the cosine function is even. Therefore:

Yss = (3/pi) ∫(0 to pi) cos(2t)sin(8.1) dt

Using the substitution u = 2t, du = 2 dt, we can rewrite this integral as:

Yss = (3/2pi) ∫(0 to 2pi) cos(u)sin(8.1) du

Using the identity sin(a+b) = sin(a)cos(b) + cos(a)sin(b), we can rewrite this as:

Yss = (3/2pi) sin(8.1) ∫(0 to 2pi) cos(u) du

The integral of cos(u) over one period is zero, since the cosine function is even. Therefore:

Yss = 0

Thus, the steady-state response to the given input function is zero.

\(y = 2*4^x\)

By comparison:

\(b = 4\)

Another instance is:

\(y = 2(-4)^x\)

By comparison

\(b = -4\)

The value of k is 39.(constant)

The value of  a = -24 and b = 0. (constant)

A. To find the values of a and b, we can start by using the information about the local minimum and maximum points to set up a system of equations.

First, we know that the derivative of the function, cubic polynomial function f'(x), is equal to zero at both the local minimum and maximum points:

f'(x) = 12x^2 + 2ax + b

f'(-2) = 12(-2)^2 + 2a(-2) + b = 0  (local minimum at x = -2)

f'(0) = 12(0)^2 + 2a(0) + b = b  (local maximum at x = 0)

We also know that the second derivative of the function, f''(x), changes sign at both of these points.

f''(x) = 24x + 2a

f''(-2) = 24(-2) + 2a < 0 (concave down at x = -2)

f''(0) = 24(0) + 2a > 0 (concave up at x = 0)

Using these equations and inequalities, we can solve for the values of a and b.

From f'(-2) = 0, we have:

-48 - 2a + b = 0

From f'(0) = 0, we have:

b = 0

Substituting b = 0 into the first equation, we have:

-48 - 2a = 0

a = -24

Therefore, the values of a and b are a = -24 and b = 0.

B. To find the value of k, we can integrate f(x) from 0 to 1 and set the result equal to 32:

∫[0,1] f(x) dx = ∫[0,1] (4x^3 - 24x^2 + k) dx = [x^4 - 8x^3 + kx]_0^1

= (1^4 - 8(1)^3 + k(1)) - (0^4 - 8(0)^3 + k(0)) = 1 - 8 + k = -7 + k

Therefore, we have:

∫[0,1] f(x) dx = -7 + k = 32

Solving for k, we have:

k = 32 + 7 = 39

The maximum amount Kathy can contribute to a SEP IRA for 2021 is determined by her net self-employment income. It is calculated as 25% of her net earnings, up to a certain limit.

For self-employed individuals like Kathy, the maximum contribution to a SEP IRA is calculated based on their net self-employment income. In 2021, the contribution limit is 25% of net earnings, up to a maximum limit of $58,000. To calculate the maximum contribution, Kathy needs to determine her net earnings from self-employment. Net earnings are calculated by subtracting business expenses from revenues. In Kathy's case, her net earnings would be $111,000 - $42,200 = $68,800.

Since the contribution limit is 25% of net earnings, Kathy can contribute a maximum of 25% of $68,800, which is $17,200. However, it's important to note that the contribution cannot exceed the maximum limit of $58,000.

A hole in the ground in the shape of an inverted cone is 18 meters deep and has radius at the top of 13 meters. This cone is filled to the top with sawdust. The density, rho, of the sawdust in the hole depends upon its depth. The mass of the sawdust in the hole is 6689.707396545126 kg.

The density of the sawdust in the hole is given by rho(x)=2.1−1.5e−1.5xkg​/m3. This function gives the density of the sawdust at a depth of x meters. The volume of the sawdust in the hole can be calculated using the formula for the volume of a cone:

V = (1/3)πr2h

In this case, r = 13 and h = 18, so the volume of the sawdust is V = 1540.5 m3. The mass of the sawdust is then given by V * rho(x), which is approximately 6689.707396545126 kg.

The table does not represent a direct variation as there is mismatch of k in three expressions.

We know that any equation, which can be expressed in the form of y=kx, can be called a direct variation.

What is direct variation?

A sort of proportionality known as "direct variation" occurs when one quantity directly changes in response to a change in another quantity. This suggests that if one quantity increases, the other quantity will also increase proportionately. Similar to the last example, if one quantity declines, the other amount also declines. The link between direct variation and the graph will be linear, resulting in a straight line.

For the first value of x and y, x=-4 and y=-8

Thus, it can be expressed as -8 = 2*-4, hence k=2

For the second value of x and y, x=-2 and y=-4

Thus, it can be expressed as -4 = 2*-2, hence again k=2

For the third value of x and y, x=6 and y=18

Thus, it can be expressed as 18 = 3*6, thus k here is 3 and not 2

Hence, this table does not represent a direct variation as there is mismatch of k in three expressions.

The inverses of these transformations and compositions include the following:

a. \(T_{(-5,1)}\)

b. \(T_{(-2,-3)}R_{0,180^{\circ}}\)

In Mathematics and Geometry, a transformation is the movement of a point from its initial position to a new location. This ultimately implies that, when a geometric figure or object is transformed, all of its points would also be transformed.

By critically observing the transformation rule and compositions, we can reasonably infer and logically deduce the following:

\(T_{(5,-1)}\) = translation right 5 units and 1 unit down, so the inverse is left 5 units and 1 unit up i.e \(T_{(-5,1)}\)

\(R_{0,180^{\circ}}T_{(2,3)}\) = rotation of 180° about the origin and translation right 2 units and 3 unit up, so the inverse is \(T_{(-2,-3)}R_{0,180^{\circ}}\)

The percent change in volume between cylinders A and B is that Cylinder B is 100% bigger than cylinder A (aA.

Calculate the volume of cylinder A using the formula V_A = πr_A^2h_A, where r_A is the radius of cylinder A and h_A is the height of cylinder A.

V_A = π(7^2)(5) = 245π

Calculate the percent change in volume between cylinders A and B using the formula ((V_B - V_A) / V_A) * 100%, where V_B is the volume of cylinder B.

((V_B - V_A) / V_A) * 100% = ((490π - 245π) / 245π) * 100%

= (245π / 245π) * 100%

= 100%

Since the percent change is 100%, it means cylinder B is 100% bigger than cylinder A.

However, we need to express this in terms of the answer choices provided. To do that, we calculate the percentage by which cylinder B is smaller than cylinder A.

100% - 100% = 0%

Finally, since cylinder B is not smaller but actually bigger than cylinder A, we subtract 0% from 100% to get the percentage by which cylinder B is bigger than cylinder A.

100% - 0% = 100%

Therefore, cylinder B is 100% bigger than cylinder A, which matches none of the given answer choices.
