Can you please help me with this question

10. The population F of fish in a pond is modeled by F(t)=720e0.03t, where f is measured in years. Researchers estimate that the pond can support at most 1400 fish. After how many years will the fish population reach its maximum? Round to the nearest year. Enter a number only (no units). You may use SymPy. Hint: If you use a solving function, add the argument domain = s. Reals to restrict the answer to real solutions only
