Question

Very important! help needed! timed!

Use the dot product to find [v] when v = -6i.

a.0

b.-6

c.36

d.6

Answer 1

d

Explanation:

You cannot use the dot product on a single vector

To find the magnitude of v = - 6i, then

| v | =
`√((-6)^2)` =
`√(36)` = 6 → d

Answer 2

6

Explanation:

I think you mean |v|... you wouldn't need dot product for that...

It is just sqrt(6^2)=6
