. A lake is stocked with fish of a new variety. The size of the lake, the availablity of food, and the number of other fish restrict the growth of that type of fish in the lake to a limiting value of 4000. The populatio of fish in the lake after time t, in months, is given by the equation: P(t) = 1+ 9e-0.008t (d) Find the population after 12 months (e) Find the population after 18 months (f) Find the population after 24 months
