Question

The endpoints of a line segment are at the coordinates (3, 4, 6) and (5, 7, 2). What is the midpoint of the segment?
(Points : 5)
(4, 1.5, 2)

(7, 18, 10)

(1, 15, 14)

(1.5, 2, 3)
My answer, A.

Answer 1

use the distance formula?

Answer 2

5.5?

Answer 3

Sorry, I should have posted the answer w/the question.
3.7

5.5

7.9

Answer 4

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

Answer 5

distance = \(\large \sqrt{(6-8)^2 + (4-3)^2 + (1-4)^2 } \)

simplify

Answer 6

3.7? :D
