Question

What is the distance from (3 1/2, 5) to (3 1/2, –12)?

Answer 1

Answer:

0, 17

3 1/2, 5

-3 1/2, -12

0, 17

Answer 2

Answer:

17

Step-by-step explanation:

First label the 2 points.

A = (3, 1/2, 5), B = (3, 1/2, -12)

Then calculate the vector from A to B:

$\vect{AB} = (0, 0, -17)$

And then calculate it's length by the formula:

$||\vect{a}|| = \sqrt{x^2 + y^2 + z^2}$, where x, y, z are the coordinates related to the vector.

$||\vect{AB}|| = \sqrt{0^2 + 0^2 + (-17)^2} = \sqrt{(-17)^2} = |17| = 17$
