Answer:
The geometric mean of 14 and 20 is 16.73.
Step-by-step explanation:
It is required to find the geometric mean of 14 and 20. Let the numbers are :
a = 14 and b = 20
The geometric mean for two numbers is given by :
![M=\sqrt{ab}](https://tex.z-dn.net/?f=M%3D%5Csqrt%7Bab%7D)
Plugging the values in above formula as follows :
![M=\sqrt{14\times 20}\\\\M=\sqrt{7\times 2\times 5\times 4} \\\\M=16.73](https://tex.z-dn.net/?f=M%3D%5Csqrt%7B14%5Ctimes%2020%7D%5C%5C%5C%5CM%3D%5Csqrt%7B7%5Ctimes%202%5Ctimes%205%5Ctimes%204%7D%20%5C%5C%5C%5CM%3D16.73)
So, the geometric mean of 14 and 20 is 16.73.

Answer:
2
Step-by-step explanation:
Solving the given equation for y, you have ...
2x +4y = -64
4y = -2x -64
y = -1/2x -16
The coefficient of x is the slope of the given line: -1/2. The slope of the perpendicular line is the opposite reciprocal of this:
-1/(-1/2) = 2
The slope of the perpendicular line is 2.
If x represents the number of hours Shelton worked, then the expression 10.25x shows how much Shelton is paid for these x hours ($10.25 for an hour).
After taxes, social security, and his health care plan were deducted he earned
10.25x - 0.21(10.25x).
This means that taxes, social security, and his health care plan form 21% (0.21 as decimal) from 10.25x.
Answer: 21%
In order to get the answer to this question you have to remember that if the exponent is positive you need to move to the right, and if the exponent is negative you got to move to the left.
![4.9\times10^8](https://tex.z-dn.net/?f=4.9%5Ctimes10%5E8)
- Positive so move to the right 8 times....
![4.9\times10^8 = 490000000.](https://tex.z-dn.net/?f=4.9%5Ctimes10%5E8%20%3D%20490000000.)
![= 490000000.](https://tex.z-dn.net/?f=%3D%20490000000.)
Therefore the answer is "490000000."
Hope this helps!
