Question

The function ?(ℎ) = LaTeX: 4e^{-0.8h}4 e − 0.8 h can be used to find the number of milligrams D of a certain drug that is in the patient’s bloodstream h hours after the drug has been administered. How long until there is only 0.02 milligrams left in the patient's bloodstream?

Answer #1

Solution:

is the function which can be used to find the number of milligrams D of a certain drug that is in the patient's bloodstream h hours after the drug has been administered.

Put D(h) = 0.02 to find the time when drug is only 0.02 milligrams left in patient's bloodstream

-4.605 - 0.693 = -0.8h

-5.298 = -0.8h

h = 6.6225 hours

Therefore, **after 6 hours and 37 minutes, there will be
0.02 mg of drug left in patient's bloodstream.**

A certain drug has a half-life in the bloodstream of 2 hours.
Doses of D mg will be administered every 6 hours, with D to be
determined. a) What percentage of a single dosage remains after 6
hours?; after 12 hours?
b) Express the number of milligrams of drug in the bloodstream
after the nth dose has been administered as a geometric series.
c) What is the long-run level of the drug in the bloodstream,
assuming that D mg continue...

An exponential decay function can be used to model the number of
grams of a radioactive material that remain after a period of
time. Carbon-14 decays over time, with the amount remaining after
t years given by y=y 0 e Superscript negative 0.00012378
ty=y0e−0.00012378t, where y0 is the original amount. If the
original amount of carbon-14 is 450450 grams, find the number of
years until 346346 grams of carbon-14 remain.

As a third year medical, you find yourself the only “doctor” on
duty in the Emergency Room (ER) when the residents, having been
working for 36 hours, are trying to catch some sleep. A 62 year old
male patient has been brought into the ER that is severely
dehydrated. Not wanting to disturb the residents, you tried to
administer water orally, but the patient vomited. Realizing the
emergency and need to hydration, you grab the first sterile fluid
available to...

Question #4: # Years ago the Romans used a different system to
represent numbers. # Instead of using the digits (0, 1, 2, 3, 4, 5,
6, etc.), the Romans # formed numbers by joining combinations of
the characters # (I, V, X, L, C, D, and M). # Roman Numeral
characters and their integer values are: # I = 1, V = 5, X = 10, L
= 50, C = 100, D = 500, and M...
