Given $\mathbf{u}=\langle- 2,5\rangle$ and $\mathbf{v}=\langle 4,3\rangle,$ find each vector. Do not use a calculator. $$-5 \mathbf{v}$$
Added by Jose Miguel K.
Step 1
To do this, we simply multiply each component of $\mathbf{v}$ by $-5$: $$-5\mathbf{v} = -5\langle 4,3angle\rangle = \langle -20,-15angle\rangle$$ Show more…
