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...

A graphing calculator is recommended. A drug is administered to a patient, and the concentration of the drug in the bloodstream is monitored. At time t ≥ 0 (in hours since giving the drug) the concentration (in mg/L) is given by c(t) = 5t/ t2 + 1 . Graph the function c with a graphing device. (Round your answers to two decimal places.) (a) What is the highest concentration of drug that is reached in the patient's bloodstream? (b) How...
