Question: If u = (-7, -4) and v = (-16, 28) with an angle 0 between the vectors, are u and v parallel or orthogonal? Explain.

If u = (-7, -4) and v = (-16, 28) with an angle 0 between the vectors, are u and v parallel or orthogonal? Explain. O The vectors are parallel because cos 0 = -1. O The vectors are parallel because u . v = 0. O The vectors are orthogonal because cos 0 = -1. The vectors are orthogonal because u . v = 0
