For v= -5i - 2j, find unit vector u in the direction of v, and write your answer as a linear combination of the standard unit vectors i and j.

Third option

Step-by-step explanation:

A unit vector is a vector that has magnitude 1.

To find a unit vector in the direction of the vector v we must first calculate the magnitude of v and then divide the vector v by its magnitude

The vector v is:

v = -5i - 2j

The magnitude of the vector is:

Now we divide the vector v by its magnitude

Simplifying we have to
