Question
question given vector v = <5, -5>, find -2v. answer attempt 2 out of 3 answer: < > submit answer
Step1: Multiplicación escalar de vector
Para un vector $\mathbf{v}=\langle a,b
angle$ y un escalar $k$, $k\mathbf{v}=\langle ka,kb
angle$. Aquí $\mathbf{v}=\langle 5, - 5
angle$ y $k=-2$.
Step2: Calcular las componentes
Multiplicamos cada componente de $\mathbf{v}$ por $-2$.
$(-2)\times5=-10$ y $(-2)\times(-5) = 10$.
