Question

Use the dot product to determine which of the following vector pairs are orthogonal.
a. v1 = (-5,5) and v2 = (1,1)
Score


b. v1 = (154,169.4) and v2 = (88,64)

Answer 1

the dot product of the first vector pair is -5*1+5*1=0 so these two vectors are orthogonal

Answer 2

oh okay that makes sense thank you
