Let $\mathbf{r}=\langle 3,-2\rangle, \mathbf{s}=\langle- 1,5\rangle,$ and $\mathbf{t}=\langle 4,-6\rangle .$ Perform the operations indicated. Write the vector answers in the form $\langle a, b\rangle$ $$\frac{r+s}{2}$$
Added by Melissa T.
Step 1
First, we need to add $\mathbf{r}$ and $\mathbf{s}$: $$\mathbf{r}+\mathbf{s}=\langle 3,-2angle\rangle+\langle -1,5angle\rangle=\langle 2,3angle\rangle$$ Show more…
