Use the dot product to determine whether v and w are orthogonal. v=3i+12j,w=4i-j Select the correct choice below and ll in the answer box to complete your choice. 0 A. The vectors v and w are orthogonal because their dot product is D. O B. The vectors v and w are not orthogonal because their dot product is D. Use the dot product to determine whether v and w are orthogonal. v = 6i, w = - 2] Select the correct choice below and ll in the answer box to complete your choice. 0 A. The vectors v and w are orthogonal because their dot product is D. O B. The vectors v and w are not orthogonal because their dot product is D. Find the angle, in degrees, between v and w. 41:: 41: 31! 311 = '+ I l = I+ I l v Bees 3I 63m 3 w 7cos 2I 75m 2] The angle between v and w is |:|. Find the cross products u x v and v x u for the vectors u = (3,4, - 8) and V: ( 1, - 1,1). u x v = (D) i + (D) j + (D) k (Simplify your answers.)
