Multiple Choice

Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, $\operatorname{proj}_{\mathbf{v}} \mathbf{u}$ .
- $\mathbf { u } = \langle 9,8 \rangle , \mathbf { v } = \langle 1,2 \rangle$

A) $\langle 0.5,1 \rangle + \langle 8.5,7 \rangle$
B) $\langle 1,2 \rangle + \langle - 2,1 \rangle$
C) $\langle 5,10 \rangle + \langle 4 , - 2 \rangle$
D) $\langle 1,2 \rangle + \langle 8,6 \rangle$
