Question

Vector u has a initial point of (3,3) and a terminal point (7,2). whats the magnitude

Answer 1

The check thing then 17

Answer 2

√17

Explanation:

As we go from (3, 3) to (7, 2), x increases by 4 and y decreases by 1. We want the distance from one point to the other and will apply the Pythagorean Theorem to calculate that.

In this situation, a^2 + b^2 = c^2 becomes

4^2 + 1^2 = 17, and so the length of the hypotenuse, and

thus the magnitude of this vector, is √17.
