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

RUDIKE [14]

Answer:

$||AB|| = 11.8743$

Step-by-step 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:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}$

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

$||AB|| = \sqrt{(-4-(-8))^2+(8-(-3))^2+(0-(-2))^2}$

$||AB|| = \sqrt{4^2 + 11^2 + 2^2}$

$||AB|| = 11.8743$
