Question

Vectors once again right answers only PLEASE HELP ME THANK YOU

Answer 1

You have vector
`\vec{a}=(-3,2).`

The magnitude of the vector
`\vec{a}=(x_a,y_a)` can be obtained using formula:

`|\vec{a}|=√(x_a^2+y_a^2).`

Then

`|\vec{a}|=√((-3)^2+2^2)=√(9+4)=√(13).`

Answer: correct choice is A.
