The concentration in micrograms per milliliter is modeled by the function:
[tex]C(t)=\frac{3t}{0.08t^2+5.2}[/tex]
QUESTION 1
25 minutes after the injection, the following substitution can be made into the function to get the concentration:
[tex]t=25[/tex]
Therefore, the concentration will be:
[tex]\begin{gathered} C(t)=\frac{3(25)}{0.08(25)^2+5.2} \\ C(t)=1.36 \end{gathered}[/tex]
Therefore, the concentration is 1.36 milligrams per milliliter after 25 minutes.
