Question

The magnitude of a given vector with end points (4, 4, 0) and (– 2, – 2, 0) must be

1 point

(a) 6

(b) 6 (root 2)

(c) 4

(d) 2 (root 2)


​

Answer 1

Answer:

b) 6√2

Explanation:

magnitude = length of vector = distance between the points

= √(x1-x2)^2 + (y1-y2)^2 + (x1-x2)^2

=√ (4+2)^2 + (4+2)^2 + 0-0)^2

= √ 36+36+0

= √36*2

= 6√2

Answer 2

☆Your Answer☆

$6 \sqrt{2}$

magnitude = length of vector = distance between the points.

$= \sqrt{(x1 - {x2)}^{2} } + (y1 - {y2)}^{2} + (x + {x2)}^{2}$

$= \sqrt{36 + 36 + 0}$

$= \sqrt{36} \: \: 2$

$= 6 \sqrt{2}$
