Answer:
Every hour, the medicine concentration decays by a factor of 4%.
Step-by-step explanation:
The relationship between the elapsed time, <em>t</em>, in minutes, since the medicine was ingested, and its concentration in the bloodstream, <em>C</em> (<em>t</em>), is:
The decay function is:
Here,
<em>y</em> = final amount
<em>a </em>= initial amount
<em>r</em> = decay rate
<em>t</em> = time
From the provided expression the decay rate is:
Thus, every hour, the medicine concentration decays by a factor of 4%.

Answer:
The approximate loudness of a rock concert with a sound intensity of 
is 110 Db.
Step-by-step explanation:
The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is :
We are supposed to find What is the approximate loudness of a rock concert with a sound intensity of
So, 
Substitute the values in the formula :
L=110 Db
So, the approximate loudness of a rock concert with a sound intensity of is 110 Db.
The answer would be 1/15.
Find the greatest common multiple of each fraction, then add them. You will get 1/15 out of it.
