For v= 4i - 5j, 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.

a.

Step-by-step explanation:

The given vector is v= 4i - 5j

The magnitude of this vector is;

The unit vector u in the direction of v is;

We rationalize to get

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
