A small lake is stocked with a certain species of fish. The fish population is modeled by the function egin{equation*} P = frac{10}{1 + 4e^{-0.7t}} end{equation*} 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 3 years. (Round your answer to the nearest whole fish.) fish (b) After how many years will the fish population reach 5000 fish? (Round your answer to two decimal places.) yr

A small lake is stocked with a certain species of fish. The fish population is modeled by the function P = 14/1 + 4e−0.5t 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 3 years. (Round your answer to the nearest whole fish.) fish (b) After how many years will the fish population reach 7000 fish? (Round your answer to two decimal places.) yr
