Question

Can I please get answer quickly I just need to confirm I got it right

Answer 1

We want to find the magnitude of the vector (-3, 4)

Magnitude of a vector is given as

`\begin{gathered} |v|=√(x^2+y^2) \\ (x,y)=(-3,4) \\ we\text{ have } \\ =√((-3)^2+4^2) \\ =√(9+16) \\ =√(25) \\ =5 \end{gathered}`

Hence the answer is 5 units, the last option
