Pollution from a factory is entering a lake. The rate of concentration of the pollutant at time t is given by P'(t) = 119t , 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 100 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
