Suppose an oral dose of a drug is taken. Over, time, the drug is assimilated in the body and excreted though the urine. The total amount of the drug that has passed through the body in T hours is given by ∫ 0 T E ( t ) d t , where E ( t ) is the rate of excretion of the drug. A typical rate-of-excretion function is E ( t ) = t e − k t , where k > 0 and t is the time, in hours. Use this information for Exercises 49-50. A physician prescribes a dosage of 100 mg. Find k .
