In Ra, you are given the vectors . u = (3, -4, 1) a = (4, 11, -4) x = (5, -8, -6) Then ux (a x x) (a xx) xuSuppose a, b, C are vectors in R3 for which det[a b c] = 2 Then (11:1) - {(911} x (1%)) = |:| Which orientation of Ra does the set{_12l::1 i:l1 :1} represent? For the orientation, enter +1 for Right Hand Orientation [positive orientation) and 1 for Left hand Orientation (negative orientation). Answer: In 1Rs, find a general equation for the plane Pi which meets the plane P2 : -1lr + 16y - 82 = 4 at a right angle and contains the line e: x = (3, 3, 1) + t(14, 4, -6), tER Answer: one such general equation for Pi is I + y + 2 =
