Q. After a certain medicine is ingested, its concentration in the bloodstream changes over time.The relationship between the elapsed time, t, in minutes, since the medicine was ingested, and its concentration in the bloodstream, Cminute (t), in mg/L, is modeled by the following function:Cminute (t)=61⋅(0.96)tComplete the following sentence about the hourly rate of change in the medicine concentration. Round your answer to two decimal places.Every hour, the medicine concentration decays by a factor of □
Understand function: Understand the given function.The function Cminute(t)=61×(0.96)t describes how the concentration of the medicine changes over time in minutes. The base of the exponent, 0.96, represents the decay factor per minute.
Convert time to hours: Convert the time from minutes to hours.Since we are interested in the hourly rate of change, we need to find the decay factor for one hour. There are 60 minutes in an hour, so we need to evaluate the decay factor for t=60.
Calculate hourly decay factor: Calculate the hourly decay factor.We substitute t=60 into the function to find the concentration after one hour.Cminute(60)=61×(0.96)60
Perform calculation: Perform the calculation.Using a calculator, we raise 0.96 to the power of 60.(0.96)60≈0.086352314
Find concentration after one hour: Multiply the result by the initial concentration to find the concentration after one hour.Cminute(60)=61×0.086352314Cminute(60)≈5.26749118389mg/L
Determine decay factor: Determine the decay factor for one hour.To find the decay factor, we need to compare the concentration after one hour to the initial concentration.Decay factor = Initial concentrationCminute(60)Decay factor ≈61mg/L5.26749118389mg/LDecay factor ≈0.08635231449
Round decay factor: Round the decay factor to two decimal places. The decay factor rounded to two decimal places is approximately 0.09.
