Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions, can be m

odeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 -160x + 300. The variable x is the number of televisions sold. If 150 televisions are sold, what is the profit?

Answer:

50,700

Step-by-step explanation:

3x^2 + 180x - (3x^2 - 160x + 300) = profit

3x^2 + 180x - 3x^2 + 160x - 300 = profit

340x - 300 = profit

so if 150 televisions are sold...x = 150

340(150) - 300 =

50,700 <==

Which function has an average rate of change of -4 over the interval [-2,2]?
kolbaska11 [484]

Only p(x) has an average rate of change of -4 over [-2, 2].

Find the average rate of change of each given function over the interval [-2, 2]]:

The average rate of change of m(x) over [-2, 2]:

<h3>What is the average rate?</h3>

The average rate of change = \frac{m(b)-m(a)}{b-a}

Where, a = -2, m(a) = -12

b = 2, m(b) = 4

Plug the values into the equation

The average rate of change

=\frac{4-(-12)}{2-(-2)} =\frac{16}{4}

The average rate of change = 4

The average rate of change of n(x) over [-2, 2]:

The average rate of change = \frac{n(b)-n(a)}{b-a}

Where, a = -2, n(a) = -6

b = 2, n(b) = 6

Plug the values into the equation

The average rate of change

=\frac{6-(-6)}{2-(-2)} \\=\frac{12}{4}

The average rate of change = 3

The average rate of change of q(x) over [-2, 2]:

The average rate of change = \frac{q(b)-q(a)}{b-a}

Where, a = -2, q(a) = -4

b = 2, q(b) = -12

Plug the values into the

The average rate of change = \frac{-4-12}{2-(-2)}

= \frac{-16}{4}

The average rate of change = -2

The average rate of change of p(x) over [-2, 2]:

The average rate of change = \frac{p(b)-p(a)}{b-a}

Where, a = -2, p(a) = 12

b = 2, p(b) = -4

Plug the values into the equation

The average rate of change = \frac{-4-12}{2-(-2)}

=\frac{-16}{4}

The average rate of change = -4

The answer is D.

Only p(x) has an average rate of change of -4 over [-2, 2].

Complete the equation of the line through<br> (-10, 3) and (-8, -8).
ad-work [718]

The answer is y = -5.5x - 52.

First, let's find the slope of the line.

m = Δy/Δx

  • m = -8 - 3 / -8 - (-10)
  • m = -11 / -8 + 10
  • m = -11/2
  • m = -5.5

Now, substitute the slope and one of the given points in the point slope equation.

<u>y - y₁ = m (x - x₁)</u>

  • y - 3 = -5.5 (x - (-10))
  • y - 3 = -5.5 (x + 10)
  • y - 3 = -5.5x - 55
  • y = -5.5x - 52
