- Pollution from a factory is entering a lake. The rate of concentration of the pollutant at time t is 5 given by P'(t) = 126t², where t is the number of years since the factory started introducing pollutants into the lake. Ecologists estimate that the lake can accept a total level of pollution of 600 units before all the fish life in the lake ends. Can the factory operate for 2 years without killing all the fish in the lake? Set up the integral that would determine the pollution level after 2 years. 2 5 126t 2 dt Can the factory operate for 2 years without killing all the fish in the lake?
