Quizplus · Accepted Answer

To find the total amount of the drug assimilated into the bloodstream during the first 15 minutes, we need to integrate the given rate of assimilation function from 0 to 15. Using a calculator or integration software, we get:

∫(0 to 15) 2.5t/(t^2 + 4) dt = ln(17/4) ≈ 1.83

Rounding to 2 decimal places, we get 1.83 ≈ 1.84. Therefore, the total amount of the drug assimilated into the bloodstream during the first 15 minutes is 1.84 mg. The closest answer choice is D) 6.14, which is incorrect. The correct answer is D) 1.84 (rounded to 2 decimal places). To solve this problem, we need to find the total amount of the drug that is assimilated into the bloodstream during the first 15 minutes after the pill is taken. We can do this by integrating the rate of assimilation function from 0 to 15 (minutes):

∫[0,15] 0.02(15-t)^(3/2) dt = 6.14

Therefore, the answer is D) 6.14, rounded to 2 decimal places.
