Question

In Problems 14–18, $P_1=\left(3\sqrt{2},7\sqrt{2}\right)$ and $P_2=\left(8\sqrt{2},2\sqrt{2}\right)$.

Find the unit vector in the direction of$\mathbf{v}$.

Short answer

The unit vector in the direction of$\mathbf{v}$is

Step-by-step solution

Step 1. Given information

The points are

$$\begin{gathered} P_1=\left(3\sqrt{2},7\sqrt{2}\right) \\ {P}_2=\left(8\sqrt{2},2\sqrt{2}\right) \end{gathered}$$

Step 2. Find the unit vector in the direction of v.

Let the unit vector is $\mathbf{u}$
