Multiple Choice

Use the vectors u and v to find v × u. $\mathbf { u } = 3 \mathbf { i } - \mathbf { j } + 4 \mathbf { k } \quad \mathbf { v } = 2 \mathbf { i } + 2 \mathbf { j } - \mathbf { k }$

• A) \(\mathbf { v } \times \mathbf { u } = 11 \mathbf { i } + 7 \mathbf { j } - 8 \mathbf { k }\)
• B) \(\mathbf { v } \times \mathbf { u } = 7 \mathbf { i } - 11 \mathbf { j } - 8 \mathbf { k }\)
• C) \(\mathbf { v } \times \mathbf { u } = - 7 \mathbf { i } + 11 \mathbf { j } + 7 \mathbf { k }\)
• D) \(\mathbf { v } \times \mathbf { u } = 11 \mathbf { i } + 11 \mathbf { j } + 8 \mathbf { k }\)
• E) \(\mathbf { v } \times \mathbf { u } = 7 \mathbf { i } - 8 \mathbf { j } + 8 \mathbf { k }\)
