A cube with sides 13 inches long is covered with a coat of fiberglass 0.2 inch thick. Use differentials to estimate the volume of the fiberglass shell. The volume of the fiberglass shell is approximately in For y = 120√x, find dy, given x = 9 and Ax=dx = 0.29. dy = (Simplify your answer.) 450 X (A) If production is increased from 25 per hour to 32 per hour the average cost per racket will approximately $ per racket. 1 +2+3x for For a company that manufactures tennis rackets, the average cost per racket is found to be C x21, where x is the number of rackets produced per hour. Use the differential to approximate the change in average cost per racket if production is (A) increased from 25 per hour to 32 per hour and (B) increased from 40 per hour to 47 per hour. by A cube with sides 13 inches long is covered with a coat of fiberglass 0.2 inch thick.
