I) Truefli'alse questions (circle one) you do not need to show your reasoning [2 pts each, total 10 pts]: tr || 00 a) The vector v = {123) is perpendicular to the plane with equation 3x+ 3 y True False b) If Hvxw|':0, then either v:0 or w:0 or v=vvt c) If the vectors u+ v and u v are perpendicular, then the vectors 11 and v have the same length. 2 d) For any two vectors v and w, it is the case that l|v+ w |2 = \"v |2 HI\" e) If u and v are perpendicular nonzero vectors, then (u x vjxu is parallel to v
