Question

The amount of medication in a patient's bloodstream decreases exponentially from the time the medication is administered. For a particular medication, a function that gives the amount of medication in Use this a patient's bloodstream t hours after taking a 100 mg function to find the amount of medication remaining after 2 hours. 39 mg 59 mg 49 mg 29 mg 1 2 3 4 5 28

Answer 1

`A(t)=100((7)/(10))^t^{}`

Let's solve the function for when t = 2

`\begin{gathered} A(2)=100((7)/(10))^2 \\ A(2)=100\cdot(7^2)/(10^2) \\ A(2)=100\cdot(49)/(100) \\ A(2)=49 \end{gathered}`

The answer would be 49mg
