Use the following model for the next two questions: The C(t) of a drug administered to a patient intravenously jumps to its highest level almost immediately. The concen- tration subsequently decays exponentially according to the law C(t) = Coet where C(0) = Co. The physician administering the drug would like to have m < C(t) < M, where m is the concentration below which the drug is ineffective and M is the concentration above which the drug is dangerous. (a) Suppose that immediately after a certain drug is administered, the concentration is 5 milligrams per milliliter. Ten hours later the concentration drops to 1.5 milligrams per milliliter. Determine the value of k for this drug.
