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.

Can the factory operate for 2 years without killing all the fish in the lake?
Thee factory can operate for 2 years without killing all the fish in the lake because the value
of the integral is , which is less than 600.
(Round to the nearest integer as needed.)
