Multiple Choice

Decompose v into two vectors v1 and v2, where v1 is parallel to w and v2 is orthogonal to w.
- $$\mathbf { v } = - 2 \mathbf { i } + 5 \mathbf { j } , \mathbf { w } = - 2 \mathbf { i } + \mathbf { j }$$

• A) \(\mathbf { v } _ { 1 } = \frac { 9 } { 5 } ( - 2 \mathbf { i } + \mathbf { j } ) , \mathbf { v } _ { 2 } = \frac { 8 } { 5 } \mathbf { i } + \frac { 16 } { 5 } \mathbf { j }\)
• B) \(\mathbf { v } _ { 1 } = \frac { 9 } { 5 } ( - 2 \mathbf { i } + \mathbf { j } ) , \mathbf { v } _ { 2 } = - \frac { 9 } { 5 } \mathbf { i } + \frac { 26 } { 5 } \mathbf { j }\)
• C) \(\mathbf { v } _ { 1 } = \frac { 9 } { 4 } ( - 2 \mathbf { i } + \mathbf { j } ) , \mathbf { v } _ { 2 } = - \frac { 5 } { 2 } \mathbf { i } + \frac { 21 } { 4 } \mathbf { j }\)
• D) \(\mathbf { v } _ { 1 } = \frac { 9 } { 5 } ( - 2 \mathbf { i } + \mathbf { j } ) , \mathbf { v } _ { 2 } = - \frac { 12 } { 5 } \mathbf { i } + \frac { 26 } { 5 } \mathbf { j }\)
