He cost, in millions of dollars, of building a three-story high school in new york state was estimated to be c(x) = 2.1 + 0.12x
ratelena [41]

Given cost function is

c(x) = 2.1 + 0.12x - 0.0001x^2 (20 ≤ x ≤ 400)

where x is the number of thousands of square feet

total revenue will be $0.2 million dollars per thousand square feet

Revenue is 0.2 millions per thousand square feet. we know x is the number of thousand of square feet

So R(x) = 0.2x

We know Profit = Revenue - Cost

P(x) = R(x) - C(x)

P(x) = 0.2x - (2.1 + 0.12x - 0.0001x^2)

P(x) = 0.2x - 2.1 - 0.12x + 0.0001x^2)

combine like terms

P(x) =-2.1 + 0.08x + 0.0001x^2

Profit function is

P(x) =0.0001x^2 + 0.08x - 2.1

Vlad [161]

Answer: P=5y+11x


Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- By definition, the perimeter of the figure is the sum of the lenght of each side. Then, you must make the addition as following:

P=2.8y+2x+2.2y+5x+4x

Where P is the perimeter of the figure.

- Add the like terms, then, you obtain the following expression in simplest form:

P=5y+11x
