the revenue for the school play is given by: r=-50t^2 + 300t, where “t” is ticket price in dollars. The cost to produce the play

artcher [175]

ANSWER

EXPLANATION

The revenue function is

$r = - 50 {t}^{2} + 300t$

The cost function is,

C=600-50t

In order to break even, revenue must be equal to cost.

$600 - 50t= -50 {t}^{2} + 300t$

Group every term on the LHS.

$50 {t}^{2} - 300t - 50t + 600 = 0$

$50{t}^{2} - 350t + 600 = 0$

Divide through by 50.

${t}^{2} - 7t + 12= 0$

Factor to obtain,

$(t - 3)(t - 4) = 0$

$t = 3 \: or \: t = 4$

Write a simplified polynomial expression to represent the area of the rectangle

Shtirlitz [24]

The answer is A = 2x² + 6x - 20

The area of the rectangle is:
A = l * w

l = x + 5
w = 2x - 4

A = (x + 5)(2x - 4)

Use the distributive property to calculate this:
A = (x + 5)(2x - 4)
A = x * 2x + x * (-4) + 5 * 2x + 5 * (-4)
A = 2x² - 4x + 10x - 20
A = 2x² + 6x - 20
