The profit in dollars from the sale of x expensive watches is P(x)=0.06x^2 – 3x + 3x^0.5– 5000. Find the marginal profit when (a) x=100 (b) x=2000 (c) x=6000, and (d) x=10,000.

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)
