Question

What is the distance between begin ordered pair 8 comma negative 3 comma 4 end ordered pair and begin ordered pair 6 comma negative 4 comma 1 end ordered pair? Round to the nearest tenth of a unit.

Answer 1

`d = √(14) = 3.74...`

Explanation:

To find the distance between (8, -3, 4) and (6, -4, 1), use the distance formula for (x,y,z) points. It is very similar to (x,y) points.

`d = √((x_2-x_1)^2 + (y_2-y_1)^2 + (z_2 - z_1)^2) \\d = √((8 - 6)^2 + (-3--4)^2 + (4-1)^2) \\d = √((2)^2 + (1)^2 + (3)^2) \\d = √(4 + 1 + 9)\\ d = √(14) = 3.74...`
