Question

What is the length (magnitude) of vector (6,-3)?
Sqrt 53
Sqrt 2
3
3 sqrt 5

Answer 1

hope this would help you

Answer 2

(D)

Explanation:

The given vector is
`(6,-3)`, the magnitude of the given vector is gievn as:

`m=√((x)^2+(y)^2)`

Putting
`x=6` and
`y=-3`, we get

`m=√((6)^2+(-3)^2)`

`m=√(36+9)`

`m=√(45)`

`m=3\sqrt5`

Thus, the length of the given vector is
`3\sqrt5` units.

Therefore, option D is correct.
