Use the Vectors U and V to Find V · $\mathbf { u } = 3 \mathbf { i } - \mathbf { j } + 4 \mathbf { k } \quad \mathbf { v } = 2 \mathbf { i } + 2 \mathbf { j } - \mathbf { k }$

question 44

Multiple Choice

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

• A) \(\mathbf { v } ^ { \prime } ( \mathbf { v } \times \mathbf { u } ) = 4\)
• B) \(\mathbf { v } ^ { \prime } ( \mathbf { v } \times \mathbf { u } ) = 0\)
• C) \(\mathbf { v } ^ { \cdot } ( \mathbf { v } \times \mathbf { u } ) = - 4\)
• D) \(\mathbf { v } ^ { \prime } ( \mathbf { v } \times \mathbf { u } ) = 3\)
• E) \(\mathbf { v } ^ { \cdot } ( \mathbf { v } \times \mathbf { u } ) = - 3\)
