Answer:
8 meters.
Step-by-step explanation:
Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π
π x^2 + π 4x^2= 80π
x^2 + 4x^2= 80
5x^2 = 80
x^2 = 16
x = 4.
So the radius of the larger circle = 2*4 = 8 m.
Answer:
The one at the bottom is "Neither"
The one that begins with (-4,14) is exponential.
The one that begins with (-3, 8) is a linear

Answer:
![(2,8]](https://tex.z-dn.net/?f=%282%2C8%5D)
Step-by-step explanation:
Given
The attached piece wise function
Required
The domain
To do this, we simply consider the inequalities that bound the values of x.
The inequalities are:
and ![x \ge 8](https://tex.z-dn.net/?f=x%20%5Cge%208)
Combine the first two inequalities:
and ![x \ge 8](https://tex.z-dn.net/?f=x%20%5Cge%208)
For the inequality to be true, we must have:
![2 < x \le 8](https://tex.z-dn.net/?f=2%20%3C%20x%20%5Cle%208)
In interval notation, the inequality is:
![(2,8]](https://tex.z-dn.net/?f=%282%2C8%5D)
To find the area you would had to do a an triangle formula so the final answer would be 63 inches
