A lake initially contains 2000 fish. Suppose that in the absence of predators or other causes of removal, the fish population increases by 5% each month. However, factoring in all causes, 400 fish are lost each month. How many fish will be in the pond after 5 months? (Don't round until the very end.)

Gravel is being dumped from a conveyor belt at a rate of 25 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. how fast is the height of the pile increasing when the pile is 14 ft high? (round your answer to two decimal places.) ft/min
