Question 13 (1 point) Using the exponential decay formula as per lab 6, a drug is administered every 2 hours in doses of 16mg. The drug is neutralized at an exponential rate with a decay rate constant of k = In2 hr-1. Denote by A(t) the amount of drug in the patient's system at time t hours. A(t) on [4,6) is: a) 16(1 -+ + + 18)el-2 (t-2) b) 8(1 + + 4)e-In2 (t-4) c) 21e- In 2 (t-4) d) (16 + 16e-In2 + 16e-2In2)e-In2 (t-4) e) (16 + 16(e-In2)1 + 16(e-In2)2) () None of (a) through (e) are correct U OQuestion 14 (1 point) Using the exponential decay formula as per lab 6, a drug is administered every 2 hours in doses of 16mg.
