Question
**Transcription for Educational Website:** **Topic:** Medicine Concentration in Blood Over Time The number of milligrams of medicine in a medical patient’s blood after *t* hours of receiving an IV transfusion of the medicine is given by the function \( A(t) = 28e^{-0.25t} \). **Question a:** How much medicine was originally transfused into the patient’s blood (include units)? **Question b:** How long will it take for the patient to have 1.5 milligrams of medicine remaining in their blood? Show all of your work. Round to 1 decimal place. --- **Explanation of Formula:** The formula \( A(t) = 28e^{-0.25t} \) describes an exponential decay of the medicine in the bloodstream over time: - \( A(t) \) represents the amount of medicine in milligrams remaining in the bloodstream after \( t \) hours. - \( e \) is the base of the natural logarithm, approximately equal to 2.71828. - The initial amount of medicine is 28 milligrams, which is the coefficient before the exponential. - The rate of decay is represented by \(-0.25\), indicating how quickly the medicine is eliminated from the body. To find the original amount of medicine, calculate \( A(0) \). For the time calculation, solve \( A(t) = 1.5 \) for \( t \).
