Question

What is the approximate distance between the points (-2, 3, -5) and (2, -7, 4)?

Answer 1

To approximate the distance of points with three dimension, make use of the equation,

                           d = sqrt ((x2 - x1)^2 + (y2 - y1)^2 +(z2 - z1)^2)

Substituting all the data from the points given, 
                       
                    d = sqrt ((2 - -2)^2 + (-7 - 3)^2 +(4 - -5)^2) = sqrt 197

Thus, the distance from the points is approximately 14.04 and that is letter D.
