Pollution begins to enter a lake at time t -0 at a rate (in galons per hour) given by the formula f(t) begins to remove the pollution at a rate gft) as long as the pollution remains in the lake fo-12(1-0). )-06t a. How much pollution is in the lake after 13 hours? The amount of pollution that remains in the lake after 13 hours isã] gallons. (Do not round until the final answer. Then round to the nearest hundredth as needed) b. Use a graphing calculator to find the time after t+0 when the rate that pollution enters the lake equals the rate the poilution is removed The rate of pollution entering equals the rate of the pollution being removed aftrhours. (Round to the nearest whole number as needed.) c. Find the amount of pollution in the lake at the time found in part b The amount of pollution in the lake after 20 hours is approximatelyâ¡ gallons (Do not round until the final answer. Then round to the nearest hundredth as needed.) d. Use a graphing calculator to find the time when all the pollution has been removed from the lake The time when all the pollution has been removed from the lake is â¡ hours. (Round to the nearest hundredth as needed.)
