Question
The number of people P(t) (in thousands) infected t months after an epidemic begins
is approximated by P(t) = 6 – 0.60t -
5
- where 1<t<12. When will the number
412
of people infected start to decline? According to the model, what is the maximum
number of people infected?
Suppose a certain drug is administered to a patient, with the percent of concentration
in the bloodstream t hr later (t>0) given by C(t) =
1 lt
. On what time interval
1? + 2
is the concentration of the drug increasing?
