Water is pumped out of a holding tank at a rate of 5-5e^-0.09t liters/minute, where t is in minutes since the pump is started. If the holding tank contains 1000 liters of water when the pump is started, how much water does it hold one hour later? Round your answer to one decimal place. Amount of water in tank after one hour ? liters.

I don't think I can help much. My opinion is to substitute 60 for t, then divide 1000 by that. But that's obviously incorrect.

volume of the water pumped out =integral 5-5e^-0.09t = 5t - 5(-1/0.09) e^(-0.09t) after 1 hour which is 60min , volume pumped out= 5(60)-5(-1/0.09)e^((-0.09)(60)) = 300.3 volume remained = 1000-300.3= 699.7

= 5∫ ( 1 - e ^ (-.09t ) dt [ 0, 60 ] = 5 ( t + e ^ (-.09t ) / .09 ) [ 0, 60 ] = 244.7 L Volume remain after 1 hr: 1,000 - 244.7 = 755.3

Hey, we do the best, but not guarantee it's 100% correct. It's your resposibility to double check.
