Question
The vector $\mathbf{v}$ has initial point $P$ and terminal point $Q .$ Write v in the form $a \mathbf{i}+b \mathbf{j}$; that is, find its position vector.$$P=(0,0) ; \quad Q=(-3,-5)$$
Step 1
Step 1: The position vector of a point $Q(x, y)$ with respect to an origin $P(0, 0)$ is given by $\mathbf{v} = x\mathbf{i} + y\mathbf{j}$. Show more…
