Vector u has its initial point at (17, 5) and its terminal point at (9, -12). Vector v has its initial point at (12, 4) and its
terminal point at (3, -2). Find ||3u − 2v||. Round your answer to the nearest hundredth.
2 answers:
First, we find the coordinates of the vectors u and v

Then we find the coordinates of the vector 3u-2v

Now we can find the length of the vector 3u-2v

Answer: 39.46 (<span>to the nearest hundredth</span>)
First we need to find the lengths of vector u and v. We can find this by distance formula:

and

We need to find | 3u - 2v |, which is the absolute value of 3u - 2v.
3u = 3 x 18.79 = 56.37
2v = 2 x 10.82 = 21.64
So,
| 3u - 2v | = | 56.37 - 21.64 | = | 34.73 | = 34.73
