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. p (0) = 4005 â 1158 cos (274) in this equation, pt) represents the total population size and t is the time in years). suppose we start at t=0 years. during the first 9 years, when will the population size be 4800? 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.) t = years x 6 ?
