Find the maximum profit and the number of units that must be produced and sold in order to yield the maximum profit. assume that revenue, r(x), and cost, c(x), of producing x units are in dollars.
r(x)=50x -0.5x2, c(x) = 6x + 20

in 4 days he will run   12/14

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
