Question

Let P(–2, 5) and Q(–5, 9). The component form of Vector P Q is . The magnitude of Vector P Q is . To the nearest degree, the direction angle of Vector P Q is . If Vector P Q is multiplied by the scalar –10, the new vector will be the original vector.

Answer 1

Explanation:

Answer 2

Let P(–2, 5) and Q(–5, 9).

The component form of Vector P Q is – 3, 4

The magnitude of Vector P Q is 5

To the nearest degree, the direction angle of Vector P Q is 127º

If Vector P Q is multiplied by the scalar –10, the new vector will be in the opposite direction but longer than the original vector.
