Add the lengths:

5x - 16 + 2x - 4 = 7x - 20

Since segment CD is the mid-segment of trapezoid WXYZ, it means that segment CD is parallel to both bases WX and YZ and it is also half the length of their sum. Therefore, we can use the mid-segment formula which states that the length of segment CD is equal to the average of the lengths of the bases WX and YZ.

So, we can write:

CD = (WX + YZ)/2

Since we want to find the value of XY, we need to know its length in terms of WX and YZ.

If we draw a diagonal of the trapezoid, say diagonal WZ, it will divide the trapezoid into two triangles, namely triangle WXY and triangle ZYX.

We know that the mid-segment CD is also the median of triangle WZY, so it divides it into two equal areas.

Therefore, the area of triangle WXY is equal to the area of triangle ZYX.

We can write:

1/2 * WX * CD = 1/2 * YZ * CD

Simplifying this equation by dividing both sides by CD, we get:

1/2 * WX = 1/2 * YZ

Multiplying both sides by 2, we get:

WX = YZ

Therefore, the trapezoid WXYZ is actually an isosceles trapezoid with equal bases WX and YZ.

So, we can substitute WX for YZ in the formula for CD:

CD = (WX + WX)/2

Simplifying this equation, we get:

CD = WX

Therefore, the length of segment XY is equal to the length of the shorter base of the trapezoid, which is WX.

So, the value of XY is equal to the value of WX, and we can conclude that XY = WX.

Danielle spent $23.50 on long distance charges this past month.

To determine how much Danielle spent on long distance, we need to consider her basic cell phone rate, voice mail, and text messaging charges. Here is a step-by-step explanation:

1. Danielle's basic cell phone rate each month is $29.95.
2. She pays an additional $5.95 for voice mail.
3. She also pays $2.95 for text messaging.
4. Her total bill for the month was $62.35.

Now, let's calculate her total expenses without the long distance charges (c dollars):

$29.95 (basic cell phone rate) + $5.95 (voice mail) + $2.95 (text messaging) = $38.85

Since Danielle's total bill was $62.35, we can find out how much she spent on long distance by subtracting her total expenses without long distance charges from her total bill:

$62.35 (total bill) - $38.85 (total expenses without long distance) = $23.50

So, Danielle spent $23.50 on long distance charges this past month.

The searchlight should be 1/3 feet deep at the edge of the opening. Since the paraboloid is a continuous surface, the depth will increase gradually from the edge of the opening to the vertex at (0,0,1).

Determine the depth of the searchlight shaped like a paraboloid of revolution, we need to use the equation for the standard form of a paraboloid of revolution:
z = (x^2 + y^2) / (4f)
where z is the depth, x and y are the horizontal and vertical coordinates, and f is the focal length of the paraboloid.
We know that the light source is located 1 feet from the base along the axis of symmetry, which means that the vertex of the paraboloid is at (0,0,1).
We also know that the opening is 6 feet across, which means that the horizontal distance from one side of the opening to the other is 3 feet.
Using this information, we can find the value of f:
f = (d/2)^2 / 2r
where d is the diameter of the opening (6 feet), and r is the radius of curvature at the vertex (1 foot).
f = (6/2)^2 / 2(1) = 4.5 feet
Now we can plug in the values for x, y, and f to solve for z:
z = (x^2 + y^2) / (4f)
z = (x^2 + y^2) / (4(4.5))
z = (x^2 + y^2) / 18
Since the opening is 6 feet across, we know that the maximum value of x is 3 feet. Therefore, we can use the maximum value of y (also 3 feet) to find the depth at the edge of the opening:
z = (3^2 + 3^2) / 18
z = 6/18
z = 1/3 feet
So the searchlight should be 1/3 feet deep at the edge of the opening. However, since the paraboloid is a continuous surface, the depth will increase gradually from the edge of ×the opening to the vertex at (0,0,1).

To find the derivative of the function f(x) = (3x + 1)^5(3x - 1)^6 using the Generalized Power Rule, we will need to apply both the Product Rule and the Chain Rule.

The Product Rule states that if you have a function f(x) = g(x)h(x), then f'(x) = g'(x)h(x) + g(x)h'(x).

First, let's identify g(x) and h(x) in your function:
g(x) = (3x + 1)^5
h(x) = (3x - 1)^6

Next, we'll find the derivatives g'(x) and h'(x) using the Chain Rule, which states that if you have a function y = [u(x)]^n, then y' = n[u(x)]^(n-1) * u'(x).

For g'(x):
u(x) = 3x + 1
n = 5
u'(x) = 3
g'(x) = 5(3x + 1)^(5-1) * 3 = 15(3x + 1)^4

For h'(x):
u(x) = 3x - 1
n = 6
u'(x) = 3
h'(x) = 6(3x - 1)^(6-1) * 3 = 18(3x - 1)^5

Now, we apply the Product Rule:
f'(x) = g'(x)h(x) + g(x)h'(x) = 15(3x + 1)^4(3x - 1)^6 + (3x + 1)^5 * 18(3x - 1)^5

The company should increase the quantity of capital used from 6 units to 3 units, an increase of 3 units.

The cost of capital and labor can be expressed as:

C = 44K + 11L

The company wants to limit the cost of capital and labor to $330:

44K + 11L ≤ 330

Substituting Q = aK^{0.6}L^{0.4} into the inequality, we get:

44K + 11L ≤ 330

44K + 11(Q/aK^{0.6})^{0.4} ≤ 330

44K^{1.6} + 11(Q/a)^{0.4}K ≤ 330

Solving for K, we get:

K ≤ (330 - 11(Q/a)^{0.4}) / 44K^{1.6}

Substituting K = 6, Q = aK^{0.6}L^{0.4}, and solving for L, we get:

Q = aK^{0.6}L^{0.4}

Q/K^{0.6} = aL^{0.4}

L = (Q/K^{0.6})^{2.5}/a

Substituting Q = a(6)^{0.6}(6)^{0.4} = 6a into the equation, we get:

L = (6/a)^{0.4}(6)^{2.5} = 9.585a^{0.6}

Therefore, the company is currently using 6 units each of capital and labor, and the total cost of capital and labor is:

C = 44(6) + 11(6) = 330

This means that the company is already using the maximum allowable cost. To reduce the cost, the company should use less labor or less capital.

To determine whether to use more or less labor, we can take the derivative of Q with respect to L:

∂Q/∂L = 0.4aK^{0.6}L^{-0.6}

This is a decreasing function of L, so as L increases, the quantity of product Q produced will decrease. Therefore, the company should use less labor.

To determine how much less labor to use, we can find the value of L that would reduce the cost to the maximum allowable level of $330:

44K + 11L = 330

44(6) + 11L = 330

L = 18

Therefore, the company should reduce the quantity of labor used from 6 units to 18 units, a decrease of 12 units.

To determine whether to use more or less capital, we can take the derivative of Q with respect to K:

∂Q/∂K = 0.6aK^{-0.4}L^{0.4}

This is an increasing function of K, so as K increases, the quantity of product Q produced will increase. Therefore, the company should use more capital.

To determine how much more capital to use, we can find the value of K that would reduce the cost to the maximum allowable level of $330:

44K + 11L = 330

44K + 11(18) = 330

K = 3

Therefore, the company should increase the quantity of capital used from 6 units to 3 units, an increase of 3 units.

Lee's total cost for the leaf blower was $215.50.

First, let's find the selling price of the leaf blower before sales tax was added:

The leaf blower was marked up by 150%, so the selling price is:

= [tex]80 + (\frac{150}{100}) 80[/tex]

= 80 + 120

= 200

So the selling price of the leaf blower before sales tax was $200.

Next, we need to find the amount of sales tax that Lee paid. To do this, we need to multiply the selling price by the sales tax rate:

Sales tax = 7.75% ($200)

= 0.0775 ($200)

= $15.50

Finally, we can find Lee's total cost by adding the selling price and the sales tax:

Total cost = Selling price + Sales tax

= $200 + $15.50

= $215.50

Therefore, Lee's total cost for the leaf blower was $215.50.
