Answer:

(D)

Step-by-step explanation:

The given vector is  [tex](6,-3)[/tex], the magnitude of the given vector is gievn as:

[tex]m=\sqrt{(x)^2+(y)^2}[/tex]

Putting [tex]x=6[/tex] and [tex]y=-3[/tex], we get

[tex]m=\sqrt{(6)^2+(-3)^2}[/tex]

[tex]m=\sqrt{36+9}[/tex]

[tex]m=\sqrt{45}[/tex]

[tex]m=3\sqrt5[/tex]

Thus, the length of the given vector is [tex]3\sqrt5[/tex] units.

Therefore, option D is correct.
