$d=sqrt(89)=9.434" "$ units

The distance formula $(9, 0, 1)$ and $(1, -4, -2)$

$d=sqrt((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2)$

$d=sqrt((9-1)^2+(0--4)^2+(1--2)^2)$

$d=sqrt((8^2+4^2+3^2)$
$d=sqrt(64+16+9)$
$d=sqrt(89)$

God bless....I hope the explanation is useful.

What is the distance between (9,0,1)(9,0,1) and (1,-4,-2)(1,-4,-2)?
