Answer:
Option B is correct.
Step-by-step explanation:
The distance formula used is:

We need to find distance between origin and other point (3,-4,5)
Origin is: (0,0,0)
x₁ = 0, y₁ = 0, z₁ =0 and x₂= 3, y₂= -4 and z₂ = 5
Putting values in the distance formula we get:

The Distance from the origin to the point (3, −4, 5) is 7 units.
Option B is correct.
Answer: 6.3
Step-by-step explanation:
The formula for geometric mean is given as :
G.m = 
Therefore , the geometric mean between 4 and 10 will be :
G.m = 
= 
= 2
= 6.3
