1. Determine whether the statement is true or false. Assume u, 7, and w are non-zero vec- tors.[6pts] i) The cost of movie ticket is a scalar quantity. ii) If a and b are orthogonal vectors, then a . b = 0 iii) If u and v are orthogonal to w , then u is parallel to v. iv) uxv = vxu v) If c is a real number, then | |cull = cl|ull vi) For any vector a, then a x a = 0
