Remaining time: 46:46 (min se Problem 2. (1 point) Hydrocodone bitartrate is used as a cough suppressant. After the drug is fully absorbed, the quantity of drug in the body decreases at a rate proportional to the amount left in the body, with constant of proportionality k. Suppose that the half-life of hydrocodone bitartrate in the body is 3.7 hours, and that the oral dose taken is 11 mg (a) Write a differential equation for the quantity, Q. of hydrocodone bitartrate in the body at time t, in hours, since the drug was fully absorbed Note: do not explicitly include a negative sign in your DE KO Q² (Write your answer using k.

Problem 2. (1 point) Warfarin is a drug used as an anticoagulant. After administration of the drug is stopped, the quantity remaining in a patient's body decreases at a rate proportional to the quantity remaining. Suppose that the half-life of warfarin in the body is 35 hours. Sketch the quantity, Q, of warfarin in a patient's body as a function of the time, (in hours), since stopping administration of the drug. Mark 35 hours on your graph. Write a differential equation satisfied by Q ¿Q dt (Your equation should not involve any undetermined constants.) How long does it take for the drug level in the body to be reduced to 35 percent of its original level? Report your answer with units ("hr" or "day"). time = Help for units Note You can earn partial credit on this problem.
