C-(-4,2,4). Find the distance between the point (x,y,z) and C.

Question

I had tried the points (0,0,0)-(-4,2,4) and then use the distance formula, but that has not worked. Then I tried (1,1,1), but that also did not work. I am lost. Any help is needed.

Answer 1

From the problem, it sounds like they just want you to use (x,y,z) as the other coordinate,

→ d = [(x+4)² + (y-2)² + (z-4)² ]^1/2.

 

Is there more to the stated problem, or...?
