S √ [3-2e*] dx+ -4 2 S [2ex-3] dx 3 In 2 B. dx Find the area between the curves. Area = (Type an exact answer in terms of e.)

Use the definite integral to find the area between the x-axis and f(x) over the indicated interval. Check first to see if the graph crosses the x-axis in the given interval. f(x)=8-2x²: [0,4] Set up the integral (or integrals) needed to compute this area. Use the smallest possible number of integrals. Select the correct choice below and fill in the answer boxes to ○ A. dx B. 2 S 8-2x² dx+ 4 S 2 8-2x2 dx C. dx + S dx For the interval [0,4], the area between the x-axis and f(x) is (Type an integer or a simplified fraction.)

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? 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.)

Use the definite integral to find the area between the x-axis and f(x) over the indicated interval. Check first to see if the graph crosses the x-axis in the given interval. f(x)=4x-12; [2,6] The area between the x-axis and f(x) is (Type an integer or a simplified fraction.)
