Question

Please help me solve this as I have no idea how to do it :(

Answer 1

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
