$$$\frac{4}{25}\cdot \left\langle 0, 3, 4\right\rangle$$$
Il tuo input
Calcola $$$\frac{4}{25}\cdot \left\langle 0, 3, 4\right\rangle$$$.
Soluzione
Moltiplica ciascuna componente del vettore per lo scalare:
$$${\color{DeepPink}\left(\frac{4}{25}\right)}\cdot \left\langle 0, 3, 4\right\rangle = \left\langle {\color{DeepPink}\left(\frac{4}{25}\right)}\cdot \left(0\right), {\color{DeepPink}\left(\frac{4}{25}\right)}\cdot \left(3\right), {\color{DeepPink}\left(\frac{4}{25}\right)}\cdot \left(4\right)\right\rangle = \left\langle 0, \frac{12}{25}, \frac{16}{25}\right\rangle$$$
Risposta
$$$\frac{4}{25}\cdot \left\langle 0, 3, 4\right\rangle = \left\langle 0, \frac{12}{25}, \frac{16}{25}\right\rangle = \left\langle 0, 0.48, 0.64\right\rangle$$$A
