During the time interval 0 Less than or equal to t less than or equal to 4.5, water flows into tank A at rate of a(t) = (2t-5) +
5e^(2sint) During same time interval water flows into tank B at a rate of B(t) litters per ours both tanks are empty at t = 0 graphs intersect at .892 and 2.416 During time interval 0 less than or equal to t less than or equal to k water flows into tank B at a constant rate of 20.5 litters per hour what is the difference between the amount of water in tank A and the amount of water in tank b at time t = k
