The population sizes of many animal species rise and fall over time. Suppose that the population size of a certain species can be modeled by the following.

In this equation, p(t) represents the total population size and t is the time (in years). Suppose we start at t = 0 years.

During the first 11 years, when will the population size be 4700?

Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a year. (If there is more than one answer, enter additional answers with the "or" button.)
