How many hours after injection does a maximum concentration of the drug occur in the bloodstream? round answer to nearest hundredth.

The concentration of the drug in bloodstream is maximum immediately after injection.

Step-by-step explanation:

The concentration of drug in a patient's bloodstream is modeled as an exponential function,

where

C(t) is the concentration of drug at ant time t,

C₀ is the concentration immediately after injection,

r is a rate constant, which indicates the removal of drug from body through metabolism.

We see that, the C(t) is maximum when t=0, i.e, immediately after the drug is injected.

answer: 4
