3. The rate of growth of a fish population was modeled by the equation 60, 000e -0.61 G(1) = (1 + 5p-0.61) 2 , Where t is measured in years since 2000 and G in kilograms per year. If the biomass was 25,000 kg in the year 2000, what is the predicted biomass for the year 2020? 4. Find the area enclosed by the line x = y and the parabola 4x + y =12
