A travel company uses a quadratic function to model the profit, in dollars, that it expects to earn from selling
tickets to a river cruise at d dollars per person. The
expression - d^2 + 100d – 900 defines this function.
Without graphing, find the price that would generate the
maximum profit. Then, determine that maximum profit.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
