Math Problem Statement
¿Cuál de las siguientes expresiones es verdadera? Pregunta 4Seleccione una: \vec{u} \parallel \vec{v} \, \Rightarrow \, \exists k \in \mathbb{R} \, , \, k \, \neq 0 \, \, \, / \, \vec{u} \cdot \vec{v} \, = \, k \vec{u} \parallel \vec{v} \, \Rightarrow \, \exists k \in \mathbb{R} \, , \, k \, \neq 0 \, \, / \, \vec{u} \, = \, k \cdot \vec{v} \vec{u} \parallel \vec{v} \, \Rightarrow \, \vec{u} \cdot \vec{v} \, = \, 0
