Question

Find the distance from A(-8,-3,-2) and B(-4,8,0) , find ||AB||

Answer 1

`||AB|| = 11.8743`

Explanation:

Distance between two points:

Suppose that we have two points,
`(x_1,y_1,z_1)` and
`(x_2,y_2,z_2)`. The distance between them is given by:

`D = √((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2)`

Distance from A(-8,-3,-2) and B(-4,8,0)

`||AB|| = √((-4-(-8))^2+(8-(-3))^2+(0-(-2))^2)`

`||AB|| = √(4^2 + 11^2 + 2^2)`

`||AB|| = 11.8743`
