Answer:
Step-by-step explanation:
The area of the shaded region can be calculated as the area of the semicircle less the area of the right triangle.
The area of the right triangle can be calculated as:
Where LM and MN have the same length because the internal angles are L=45°, M=90°, and N=45°. So the area is:
The diameter of the circle can be calculated using the Pythagorean theorem as:
So, the radius is
Finally, the area of the semicircle is:
So, the area of the shaded region is:
The equation represents a population of 370 animals that increases at an annual rate of 11% is .
<h3>What is an exponential function?</h3>It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x
where a is a constant and a>1.
Given that,
A population of 370 animals that increases at an annual rate of 11%
a = 370, r = 11%
=
p =
Hence, The equation represents a population of 370 animals that increases at an annual rate of 11% is .
