The answer to your queation is C
Answer:
Hence, the sphere has a radius of
and is centered at the point (1,-1,1)
Step-by-step explanation:
We have the equation

We have to take into account the relation between coordinates

by substituting we have:
![\rho=2[\frac{x}{\rho}-\frac{y}{\rho}+\frac{z}{\rho}]\\\\\rho^2=2x-2y+2z\\\\x^2+y^2+z^2=2x-2y+2z](https://tex.z-dn.net/?f=%5Crho%3D2%5B%5Cfrac%7Bx%7D%7B%5Crho%7D-%5Cfrac%7By%7D%7B%5Crho%7D%2B%5Cfrac%7Bz%7D%7B%5Crho%7D%5D%5C%5C%5C%5C%5Crho%5E2%3D2x-2y%2B2z%5C%5C%5C%5Cx%5E2%2By%5E2%2Bz%5E2%3D2x-2y%2B2z)
We have to complete squares:

Hence, the sphere has a radius of
and is centered at the point (1,-1,1)
hope this helps!!

A pattern for this rule can be created by starting with a number one and applying the rule to each consecutive number.
1 x 3 +2 = 5
5 x 3 + 2 = 17
17 x 3 + 2 = 53
5, 17, 53, etc....
Answer:
2(2x + 1)
Step-by-step explanation:
4x = 2 * 2x
2 = 2 * 1
