using Matlab:
A drug administered to a patient produces a concentration in the
bloodstream given by
c(t)=Ate^(-t/3)
milligrams per milliliter, t hours after A units have been
injected. The maximum safe concentration is 1.00 mg/mL.
What amount should be injected to reach this maximum safe
concentration, and when does this maximum occur? (Use calculus to
find the time when a maximum occurs. Then set c(tmax) = 1 to solve
for A.)
An additional amount of this drug is to be administered after the
patient falls to 0.25 mg/mL. Determine to the nearest minute, when
this second injection should be given.
Set up an equation 0.25 = Ate-t/3 in appropriate function
form
Find the answer using bisection with approximate first guesses. How
many steps did it take to reach appropriate accuracy?
Find the answer using Newton-Raphson with one of your starting
guesses. How many steps did this method take?
Find the answer using the secant method with the starting guesses
from (b). How many steps did this method take?
Assume that the concentration from consecutive injections is
additive and that 75% of the amount originally injected is
administered in the second injection. When is it time for the third
injection?

A graphing calculator is recommended. A drug is administered to a patient, and the concentration of the drug in the bloodstream is monitored. At time t ≥ 0 (in hours since giving the drug) the concentration (in mg/L) is given by c(t) = 5t/ t2 + 1 . Graph the function c with a graphing device. (Round your answers to two decimal places.) (a) What is the highest concentration of drug that is reached in the patient's bloodstream? (b) How...

The antifungal drug anidulafungin is administered by IV infusion. The maximum infusion rate is achieved when 260 ml of anidulafungin solution, which has a concentration of 0.77 mg/ml, are delivered in 3 hours. What is the maximum infusion rate in milligrams per minute? A loading dose of voriconazole consists of 5 mg for every kilogram of body mass. This dose is administered as two IV infusions separated by 12 hours. The concentration of the solution is 10 mg/ml. If a...
