Profit = Revenue less Costs. Thus, Revenue = Profit(x) + Costs(x).
Here,
Profit(x) = P(x) = -2x^2 + 20x - 17, and Costs(x) = 17 + 10x. Thus,
Revenue(x) = R(x) = -2x^2 + 20x - 17 + 17 + 10x
R(x) = -2x^2 + 30x (answer)
Position vector R = < 4,0,1>
(given point)
normal vector n = < 3,-1,9>
equation:
n(r-R) = 0
3(x-4) - y + 9(z-1) = 0
