Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.
___
For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.

6:7 or 6/7
Ratio of all books (13) to used books (7) is
13:7 or 13/7
Answer:
A. add the areas of both bases to the rectangular area around the cylinder.
Step-by-step explanation:
If we flatten out the cylinder we would have two circles and a rectangle. When you roll up the rectangle, it would make the body of the cylinder. Surface area by definition the total area the surface of an object occupies.
So to get it, we add up the different shapes that make up the cylinder, which is the two circles and the rolled up rectangle.
