For this problem, use x^2 for a? and sqrt(n) for vn as needed. Remember to use to start and end your vectors; some answers may not be vectors. Using the vectors u = (3, -4) and v = (-2, 1), find: A. -4v B. u+ 4v Cu-V D. V- U E. 3u - 2v F. Ju G. A unit vector in the same direction as v. H. proju (v) Lu . V J. the angle between u and v (in degrees, round to 2 decimal places) K. if w = (8, y). find the value of "y" so that w and u are orthogonal
