Answer:

The terminal point of the given vector is (9,3).

Explanation:

The given vector is


\mathbf{a}=\left<5,2\right>

If initial point is
P(x_1,y_1) and terminal point is
Q(x_2,y_2), then vector PQ is defined as


\overrightarrow{PQ}=<x_2-x_1,y_2-y_1>

Initial point is P=(4,1). Let (a,b) are the coordinates of terminal point.


<5,2>=<a-4, b-1>

On comparing both sides we get


a-4=5\Rightarrow a=5+4\Rightarrow a=9


b-1=2\Rightarrow b=2+1\Rightarrow b=3

Therefore, the terminal point of the given vector is (9,3).
