Pollution begins to enter a lake at time toO at a rate ( in gallons per hour ) given by the formula f ( 1 ) whoeret is the time ( in hours ) . At thesame time , a pollution filter beginsremove the polpollution at a rate git ) as long as the pollutias the pollution remainains in the1 4) = 9219) . 9 1 0 ) = 0. 5a . How much pollution is in the lake after 10 hours ?The amount of pollution that remains in the lake after 10 hours is 71 . 16 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 aftert = O when the rate that pollution enters the lake equals the rate the pollution is removedThe rate of pollution entering equals the rate of the pollution being removed after 24 hours( Round to the nearest whole number as needed . )C . Find the amount of pollution in the lake at the time found in partThe amount of pollution in the lakelake after 24 hours is approximately 120 gallons(Do not round until the final answerThen round to the nearest hundredth as needed . )d . Use a graphing calculator to find the time whenall the pollution has been removed from the lakeThe time when all the pollpollution has been removed from the lake is 48 hours( Round to the nearest hundredth as nredth as needed . )
