Question

For the vector (-9,3), find 1/2V, -V, and 4V

Answer 1

9514 1404 393

Answer:

• 1/2V = <-9/2, 3/2>
• -V = <9, -3>
• 4V = <-36, 12>

Explanation:

The scalar multiplier multiplies each of the components.

1/2V = <-9×1/2, 3×1/2> = <-9/2, 3/2>

-V = <(-9)(-1), (3)(-1)> = <9, -3>

4V = <-9×4, 3×4> = <-36, 12>
