Given: The function below


C(t)=(3t)/(0.08t^2+5.2)

To Determine: The concentration since 25 minutes

Solution


\begin{gathered} t=25 \\ C(t)=(3(25))/(0.08(25)^2+5.2) \end{gathered}
\begin{gathered} C(t)=(75)/(0.08(625)+5.2) \\ C(t)=(75)/(50+5.2) \\ C(t)=(75)/(55.2) \\ C(t)=1.3587* microgram-per-milliliter \end{gathered}

Please note that


1microgram=0.001milligrams

Therefore, we would convert our answer to milligrams


C(t)=(1.3587)/(1000)milligram-per-millilitter
C(t)=0.0013587milligram-per-milliliter

Hence, the concentration is 0.0014 milligram per milliliter
