$$$\frac{21}{20}\cdot \left\langle -6, -2\right\rangle$$$

Calcular $$$\frac{21}{20}\cdot \left\langle -6, -2\right\rangle$$$.

Multiplica cada coordenada del vector por el escalar:

$$${\color{Chocolate}\left(\frac{21}{20}\right)}\cdot \left\langle -6, -2\right\rangle = \left\langle {\color{Chocolate}\left(\frac{21}{20}\right)}\cdot \left(-6\right), {\color{Chocolate}\left(\frac{21}{20}\right)}\cdot \left(-2\right)\right\rangle = \left\langle - \frac{63}{10}, - \frac{21}{10}\right\rangle$$$

$$$\frac{21}{20}\cdot \left\langle -6, -2\right\rangle = \left\langle - \frac{63}{10}, - \frac{21}{10}\right\rangle = \left\langle -6.3, -2.1\right\rangle$$$A
