Question

A drug is administered intravenously at a constant rate of ) ), for (to ) = ), for (to ? ) On the time to reach (for ) = (for increased? ), by what multiplicative factor is instead of is doubled (that is, we use ) If ), for (to ) = ), for (to , changed? ), by what multiplicative factor is the time it takes to reach half the limiting value, is doubled (to ) Similarly, if (for ) = (for increased? ), by what multiplicative factor is is doubled (to If ? , the limiting long-run value of . What is against Graph . and hours. Assume there is no drug in the body initially. Your answer will contain , in milligrams, of the drug in the body at time . (Set up and) Solve a differential equation for the quantity, mg/hour and is excreted at a rate proportional to the quantity present, with constant of proportionality

Explanation / Answer

change = incoming - outgoing...dQ /dt = r - kQ , Q(0) = 0 did you want it solved ?? ..ln| r - kQ| = -kt + c1
