Answer:
Step-by-step explanation:
If that number is greater than 1, that means that the exponential equation represents growth. If that number is less than 1 but greater than 0, that means that the exponential equation represents decay. Since ours is greater than 1, our equation is exponential growth. It means that the perent of animals adopted grows at a rate of 145% per year, with a starting number of 28 animals in the first year.
Answer:
Step-by-step explanation:
We are given a circle with a partially shaded region. First, we need to determine the area of the whole circle. To do this, we need the measurement of the radius of the circle:
Use the Pythagorean theorem to solve for the other leg of the right triangle inside the circle:
5^2 = 3^2 + x^2
x = 4
The radius is 4 + 1 cm = 5 cm
So the area of the circle is A = pi*r^2
A = 3.14 * (5)^2
A = 25pi cm^2
To solve for the area of the shaded region:
Ashaded = Acircle - Atriangles
we need to solve for the area of the triangles:
A = 1/2 *b*h
A = 1/2 *6 * 5
A = 15 cm^2
Atriangles = 2 * 15
Atriangles = 30 cm^2
Ashaded = 25pi - 30
