Question

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

Answer 1

find the length of that vector and then scale down linearly

Answer 2

I got length \[2\sqrt{6}\]

Answer 3

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?

Answer 4

yes, I did that thank you
