When a certain medical drug is administered to a patient, the number of milligrams remaining in the patient's bloodstream after t hours is modeled by D(t) = 50e−0.2t. How many milligrams of the drug remain in the patient's bloodstream after 4 hours? (Round your answer to one decimal place.) ______mg

using Matlab: A drug administered to a patient produces a concentration in the bloodstream given by c(t)=Ate^(-t/3) milligrams per milliliter, t hours after A units have been injected. The maximum safe concentration is 1.00 mg/mL. What amount should be injected to reach this maximum safe concentration, and when does this maximum occur? (Use calculus to find the time when a maximum occurs. Then set c(tmax) = 1 to solve for A.) An additional amount of this drug is to be...

HW-1 Medical Physics 1-16-2019 A dose D of a drug is given which causes the plasma concentration in a tissue to rise from 0 to Co. The concentration then begins to fall according to where b is a constant loss rate. At some later time T, what dose must be administered to raise the plasma concentration back to Co again? What would happen if the original dose, C was administered over and over again at intervals of T?
