Question

Determine whether the vectors u and v are parallel, orthogonal, or neither. u = (5,4) v = (-10,9)

Answer 1

A

Explanation:

edge answer

Answer 2

Neither

Explanation:

5 x -10 = -50

4 x 9 = 36

-50 + 36 = -14 and therefore can not be orthogonal

sqrt(25+16)=sqrt(41)

sqrt(100+81)=sqrt(181)

sqrt(41) x sqrt(181) is not equal to -14 so therefore it is not parallel

So the answer is then neither
