Question 1070965: u: <3, -1>
v: <4, 3>
w: <⅔ , -8/9 >
Which vectors involve right angles?
A.) u and v
B.) u and w
C.) v and w
D.) None are orthogonal
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
Without much calculation (just mental math),
v and w .
9w=<6,-8>
2v=<8,6>
However, if you are expected to
"show your work"
They expect you to show that
the dot product of v and w is zero.
