we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form  or
 or 
where
k is the constant of variation
in this problem we have
the point 
so

substitute


therefore
<u>the answer is</u>

Answer:
   7.92 years
Step-by-step explanation:
We want to find t such that ...
   3 = 2^(t/5)
where 2^(t/5) is the annual multiplier when doubling time is 5 years.
Taking logs, we have ...
   log(3) = (t/5)log(2)
   t = 5·log(3)/log(2) ≈ 7.92 . . . years
It will take about 7.92 years for the population to triple.

The length of a circumference: l=πD
l₁=π×5=5π
l₂=π×15=15π
Then l₂÷l₁=15π÷5π=3 and the answer is B)
