The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x. The price p in dollars that the company can charge for the product is given by p(x) = x + 5. Use the formula Revenue = price × demand to find the revenue function for the product.

The revenue function

R(x) =  - 2x² +490x +2500

Step-by-step explanation:

Explanation:-

The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x

The price p in dollars that the company can charge for the product is given by p(x) = x + 5

Revenue = price × demand

Revenue = p(x) × d(x)

Revenue = (x+5) ×(500-2x)

Revenue = x(500-2x)+5(500-2x)

Revenue = 500x - 2x² + 2500- 10x

Revenue =  - 2x² +490x +2500

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
