Question

Find ||v||. If=-2i+3j

Short answer

3.605 is the value of ||v||

Step-by-step solution

step 1

Given information: v=-2i+3j

step 2

$Weknowthat\parallel v\parallel =\sqrt{{\left(a\right)}^2+{\left(b\right)}^2}$

step 3

$$\begin{gathered} \parallel v\parallel =\sqrt{{\left(-2\right)}^2+{\left(3\right)}^2} \\ \parallel v\parallel =\sqrt{4+9} \\ \parallel v\parallel =\sqrt{13} \\ \parallel v\parallel =3.605 \end{gathered}$$
