The population sizes of many animal species rise and fall over time. Suppose that the populatio can be modeled by the following. \[ p(t)=4050-1269 \cos \left(\frac{2 \pi}{9} t\right) \] In this equation, \( p(t) \) represents the total population size and \( t \) is the time (in years). Suppose During the first 9 years, when will the population size be 4800 ?
