Assume 3 mg of a drug is injected into the person's bloodstream. As drug is metabolized, quantity diminishes at continuous rate of 6 % per hour.
a. Determine the formula for Q(t), quantity of drug remaining in body after t hours. Determine approximations to 2 decimal places for continuous rate of decay k.
b. By what percent drug level decreases during any given hour? compute approximations to 2 decimal places for constant percent rate of growth b.
c. Person should receive the additional 3 mg of drug whenever its level has diminished to 0.38 mg. When should person receive second injection? When should person receive third injection? Compute integer approximations for of second injection time t2 and third injection time t3. (in hours)
