the function d(h)=7e^(-0.38h) can be used to find the number of milligrams d of a certain drug that is in a patients bloodstream h hours after the drug has been administered. how many milligrams will be present after 1 hour? after 5 hours? after 1 hour, there will be milligrams. (round to two decimal places as needed.)

the function d(h)=7e^(-0.38h) can be used to find the number of milligrams d of a certain drug that is in a patients bloodstream h hours after the drug has been administered. how many milligrams will be present after 1 hour? after 5 hours? after 1 hour, there will be milligrams. (round to two decimal places as needed.)

Answer

Explanation:

Step1: Substitute h = 1 into the function

Substitute (h = 1) into (D(h)=7e^{- 0.38h}), we get (D(1)=7e^{-0.38\times1}=7e^{-0.38}).

Step2: Calculate the value

We know that (e^{-0.38}\approx0.6839), then (D(1)=7\times0.6839 = 4.7873).

Step3: Round the result

Rounding (4.7873) to two - decimal places, we get (4.79).

Answer:

4.79
