Question

What is the distance between (8, –3, 4) and (6, –4, 1)?

Answer 1

Do you know the distance formula for 3d coordinates?

Answer 2

noo

Answer 3

It is an extension of the one for 2 dimensions:
\( d = \sqrt{ (x_2 - x_1)^2 + (y_2 - y_1)^2} \)
But we just add the difference of the z-values.
\( d = \sqrt{ (x_2 -x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2 } \)
This is for two points (x1, y1, z1) and (x2, y2, z2)

Answer 4

Or, are you meant to take a vector approach? The magnitude of the vector between P and Q: |P-Q|. Either way should lead to what you are looking for...
