Answer:
<-3,4>
<0,-5>
Step-by-step explanation:
|-3w| = 15
3|-w| = 3|w| = 15
|w| =
|w| = 5
- If vector w is represented by <1,-9>
Then |w| = .
Therefore this is not possible.
- If vector w is represented by <-3,4>
Then |w| = .
Therefore this is possible.
- If vector w is represented by <4,5>
Then |w| = .
Therefore this is not possible.
- If vector w is represented by <-5,-3>
Then |w| = .
Therefore this is not possible.
- If vector w is represented by <0,-5>
Then |w| = .
Therefore this is possible.
(NOTE : if z vector is represented by <x,y> then |z| = )
