## kl0723 one year ago can someone help me do this one? Find a vector with same direction as (-2,4,2) but has length 6

1. IrishBoy123

find the length of that vector and then scale down linearly

2. kl0723

I got length $2\sqrt{6}$

3. IrishBoy123

well, dividing the vector you posted by that $$2 \sqrt6$$ you calculated creates the unit vector, ie the vector of length = 1, in the direction of your opening vector so next, scale it back up to length 6 yep?

yes, I did that thank you
