TELL ME HOW DID WE GET THOSES ANSWERS IN A ** PAPER PLZ** SHOW WORK
The total cost and the total revenue (in dollars) for the production and sale of x ski jackets are given by C(x) = 28x + 8,880 and R(x) = 200x - 0.4x2 for 0 ge x ge 500. Find the value of x where the graph of R(x) has a horizontal tangent line. Find the profit function P(x). Find the value of x where the graph of P(x) has a horizontal tangent line. Graph C(x), R(x), and P(x) on the same coordinate system for 0 ge x ge 500. Find the break-even points. Fii the x-intercepts of the graph of P(x). R(x) has a horizontal tangent line at x = 250 . The profit function P(x) = - 0.4x2 + 172x - 8880 . P(x) has a horizontal tangent line at x = 215 . Choose the correct graph of C(x), R(x), and P(x) graphed together. What are the break-even points? The x-intercepts of the graph of P(x) occur at x = 60,370 . (Use a comma to separate answers as needed.)Explanation / Answer
A) R(x) is horizontal when dR/dx=0
200-0.8x=0
x=250
B) P(x)=R(x)-C(x) =200x-0.4x^2-28x-8880
P(x)=-0.4x^2+172x-8880
C) P(x) has tangent when dP/dx=0
-0.8x+172=0
x=215
