To find the number of milligrams of the drug present after 1 hour, you can simply substitute h = 1 into the given function D(h):
D(1) = 7e^(-0.14 * 1)
D(1) = 7e^(-0.14)
Now, calculate this value:
D(1) ≈ 7 * 0.868 = 6.076 milligrams
So, after 1 hour, there will be approximately 6.08 milligrams of the drug present in the patient's bloodstream.
