Question

6) Assume C(x) = -0.0001x +0.05x² + 60x+800 is the cost of producing x fly rods. a. Determine the average and marginal costs for x = 400 fly rods. b. Interpret the meaning for each of your results in part (a). 7) Water flows into a conical tank at a rate of 2 ft Amin. If the radius of the top of the tank is 4 feet and the height is 6 feet, determine how quickly the water level is rising when the water is 2 feet deep in the tank. 8) Determine the location and value of the absolute extreme values of f(x) = z on (-2,2).
