To solve this you would use trigonometry. You would draw a triangle and mark the lower angle between the diagonal and horizontal line as 60. Then you would label the adjacent side as 50ft.

This means you are looking for the opposite and have the adjacent

To find the height you would do:

tan60 = Height÷50

Height = 50 tan60 = 86.6 feet (to 3 sf)

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,

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

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