As an application of part (d), suppse a brine solution containing q(t)kg of salt per liter at time t runs into a tank of water at a fixed rate and that the mixture, kept uniform by stirring, flows out at the same rate. Given that q(t)-B as t-infinity, use the result of part (d) to determine the limiting concentration of the salt in the tank as t-infinity.
Part d: B/a-lim x-infinity C/e^(ax)

Question

As an application of part (d), suppse a brine solution containing q(t)kg of salt per liter at time t runs into a tank of water at a fixed rate and that the mixture, kept uniform by stirring, flows out at the same rate. Given that q(t)->B as t->infinity, use the result of part (d) to determine the limiting concentration of the salt in the tank as t->infinity.
Part d: B/a-lim x->infinity C/e^(ax)

You'd be better off if you post the entire original problem. I don't think there's enough info here to help you.

all you use is part d which i included

holsteremission · Answer

What I mean is, the result from part D alone doesn't give enough context. What was part D about? What does this answer mean?
