2. Two separate rabbit populations are observed for 80 weeks, starting at the same time and with the same initial populations. The growth rates of two rabbit populations are modeled as follows, where : = 0 corresponds to the beginning of the observation period: "(1) = 4sin( [() +0. 1/ + 1, where r, is rabbits per week, and / is time in weeks, 1(1) = 12, where r is rabbits per week, and : is time in weeks. Below is a graph of the curves representing the rates of growth of the two populations over the observation period: 2 Copyright @ 2021 Apex Learning. See Terms of Use for further information.

Using your calculator, find (approximately) the first positive time / for which the rates of growth for the two populations are the same.B. What's the physical significance of the area between the two curves from time / = 0 until the first time where the two rates are the same? What does the area represent? C. Suppose you want to find the first time (call it ?) after the beginning of the observation period at which the two rabbit populations have identical populations. Write an equation to solve for the unknown variable T. D. Simplify your equation from part C until you can use your calculator on it. Then use your calculator to solve this equation for T
