The number of gallons, H (t), of a pollutant in a pond changes at a rate of H' (t) = 3 – 5e-0.8√/t gallons per day, where t is measured in days. There are 100 gallons of pollutant in the pond at t = 0. Is the amount of pollutant increasing or decreasing at t = 5? O Decreasing because P' (5) < 0 O Increasing because P (5) > 0 Decreasing because P (5) <0 O Increasing because P' (5) > 0.
