1 point Suppose the clean water of a stream flows into Lake Alpha then into Lake Beta and then further downstream The in and out flow for each lake is 400 liters per hour Lake Alpha contains 500 thousand liters of water and Lake Beta contains 200 thousand liters of water A truck with 400 kilograms of Kool Aid drink mix crashes into Lake Alpha Assume that the water is being continually mixed perfectly by the stream a Let x be the amount of Kool Aid in kilograms in Lake Alpha hours after the crash Find a formula for the incremental change in the amount of Kool Aid Ax in terms of the amount of Kool Aid in the lake x and the incremental change in time Ar Enter At as Deltat Ax kg b Find a formula for the amount of Kool Aid in kilograms in Lake Alpha t hours after the crash kg x 1 c Let y be the amount of Kool Aid in kilograms in Lake Beta 1 hours after the crash Find a formula for the incremental change in the amount of Kool Aid Ay in terms of the amounts x y and the incremental change in time Ar Enter At as Deltat kg Ay d Find a formula for the amount of Kool Aid in Lake Beta 1 hours after the crash kg y t
