Tutorial Exercise A small lake is stocked with a certain species of fish. The fish population is modeled by the function $\frac{12}{1 + 4e^{-0.7t}}$ where P is the number of fish (in thousands) and t is measured in years since the lake was stocked. (a) Find the fish population after 5 years. (b) After how many years will the fish population reach 6,000 fish? Step 1 The fish population after 5 years can be determined by finding P(t) where t = 5 Find the fish population after 5 years. (Round your answer to the nearest whole fish.) $\times$ fish and then multiplying the result by $\times$, since P is the number of fish in thousands. Determine the value of P when the fish population in the lake is 6,000 fish, recalling that P is the number of fish in thousands. P = $\times$ Use the given function with the value of P determined above, and solve the resulting exponential equation for t. (Round your answer to two decimal places.) t = After how many years will the fish population reach 6,000 fish? (Round your answer to two decimal places.) yr Submit Skip (you cannot come back)
