After an antibiotic tablet is taken, the concentration of the antibiotic in the bloodstream is modeled by the function

C(t) = 7(e−0.4t − e−0.6t)

where the time t is measured in hours and C is measured in µg/mL. What is the maximum concentration of the antibiotic during the first 12 hours? (Round your answer to four decimal places.)

A drug response curve describes the level of medication in the bloodstream after a drug is administered. A surge function S(t) = Atpe−kt (where t > 0) is often used to model the response curve, reflecting an initial surge in the drug level and then a more gradual decline. If, for a particular drug, A = 0.03, p = 4, k = 0.07, and t is measured in minutes, estimate the times t corresponding to the inflection points. (Round your...

A patient who has asthma is given a continuous infusion of theophylline to relax and open the air passages in his lungs. The desired steady-state level of theophylline in the patient’s bloodstream is 15 mg/L. The average half-life of theophylline is about four hours, and the patient has 5.6 L of blood in his body. This situation can be modeled by the differential equation dy/dt=a-by, where y left-parenthesis t right-parenthesis is the amount of theophylline in the blood plasma at...
