Question: Given u = 4i + 7j and v = 28i 49j, are u and v parallel or orthogonal? Explain. (5 points) The vectors are orthogonal

Given u = 4i + 7j and v = 28i 49j, are u and v parallel or orthogonal? Explain. (5 points) The vectors are orthogonal because uv = 0. The vectors are orthogonal because cos = 1. The vectors are parallel because uv = 0. The vectors are parallel because cos = 1
