Question

6. A small lake is stocked with a certain species of fish. Use the simplified logistic model 4 P(t) = 1 to describe the population at time t > 0. The parameters A and k are positive constants. (b) After 4 years the population is 1500. What will the population be after 8 years? (Note that using the properties of the exponential function, you are expected to obtain an exact numerical answer, with no unevaluated exponentials or logarithms.)
