Management has calculated that the marginal cost function for producing x chairs is C’(x) = .0015x 2- .04x + 11 dollars/unit and x denotes the number of units. Fixed costs are 700 per day. What is the total cost of producing the 111 st through 220 th units/day. 110 ∫ 220 C’(x) = 5143 to nearest integer Evaluate the definite integral 1 ∫ 2 (6/x )dx 6ln(2) The velocity of the Sea Falcon II t seconds after firing a booster rocket is v(t) = -t 2 + 20 t + 440ft/sec, 0< t< 20. Find the distance covered by the boat over the 10 second period after the booster was activated. ∫ 10 v(t) = 15200/3 Evaluate the definite integral 1 ∫ 3 e x dx e 3- e...
