The amount of drugs that will be left after 12 hours is 17.42 mg provided Sarah takes 550 mg of an antibiotic every hour.
<h3>What is exponential decay?</h3>Exponential decay can be described as a reduced amount of an original substance by a definite percentage over a period of time. It can be determined by using the formula:
where;
- y = total amount,
- a = initial amount = 550 mg
- r = the growth rate = 0.25
- t = number of growth periods = 12 hours
y = 17.42 mg
Therefore, we can conclude that the amount of drugs that will be left after 12 hours is 17.42 mg.

Answer:
<u>20,602 feet</u> is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.
Step-by-step explanation:
Given:
Mt. McKinley, which is the highest elevation in North America, is 20,320 feet above sea level.
Death Valley, which is the lowest elevation in North America, is 282 feet below sea level.
Now, to find the difference in height between the top of Mt. McKinley and the bottom of the death valley.
<em>Height of Mt. McKinley above sea level = 20,320 feet.</em>
<em>Height of Death Valley below sea level = 282 feet.</em>
Now, to get the difference in height between the top of Mt. McKinley and the bottom of the Death Valley by adding both the heights:
Therefore, 20,602 feet is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.
