Answer:
A
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given two parametric equations
and
, the first derivative can be found using the following equation:

In this problem,
and
. Finding the derivative of each of these functions with respect to
gives us the following:


Because
, that means the function is a vertical line and has an infinite first derivative.
Area of 3400 decreases by 7.25%.
Rewrite 7.25% as a decimal.
This leads to 0.0725.
So, (3400)(0.0725) = 246.5.
Now (246.5)(13 years) = 3,276.
The area after 13 years will be
3,276 km^2.
The answer is the second option
