Suppose demand d for a company’s product at cost x is predicted by the function d(x) = 0.36x2 + 810, and that the price p that the company can charge for the product is given by p(x) = x + 14. Find the company’s revenue function.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

idk what the heck he answer is, i’m just putting this here so i finish my account

my dear correct answer is option number 3
