For v=-3i-7j, find the unit vector in the same direction of v, and write your answer as a linear combination of the standard unit vectors i and j.

Step-by-step explanation:

The given vector is:

v = -3i-7j

The unit vector is found by dividing the vector by its magnitude

We have to find the magnitude first

So,

The unit vector is:

Therefor the last option is the correct answer ..

what level of math? also i don't need to be paid if i can you.
