$\mathbf { r } + \mathbf { v }$
A) $\langle 11,8 , - 1 \rangle$
B) $\langle - 28 , - 12,20 \rangle$
C) $\langle - 11 , - 8,1 \rangle$
D) $\langle 28,12 , - 20 \rangle$

Question

Quizplus · Accepted Answer

To find $\mathbf{r} + \mathbf{v}$, add the corresponding components of $\mathbf{r}$ and $\mathbf{v}$: $7 + 4 = 11$, $6 + 2 = 8$, and $-5 + 4 = -1$, resulting in $\langle 11,8,-1 \rangle$.
