Based on the direction field, determine thebehavior of y as t → ∞. If this behavior depends on the initial value ofy at t = 0, describe this dependency. Noté that the right-hand sides ofthese equations depend on t as well as y; therefore, their solutions canexhibit more complicated behavior than those in the text.squarevelocib. Dc.

Water containing 0.01 g of thischemical per liter flows into the pond at a rate of 300 L/h. Themixture flows out at the same rate, so the amount of water in the pondremains constant. Assume that the chemical is uniformly distributedthroughout the pond.a. Write a differential equation for the amount of chemical inthe pond at any time.
