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

Neither

Step-by-step 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
