Question

what do you know about multiplication of a vactor by a number
​

Answer 1

Answer:

Explanation:

in general that's what multiplication of a real number r by a vector is going to do. It'll give us something going in the same direction with r times its original magnitude. In terms of components has x component and y component . If r equals -1, then the resultant vector points in the opposite direction.
