Please help me these questions, many thanks!â
Find a vector v in the opposite direction to w = (-1, 4, 1) and with a magnitude of 6 units. Find scalars a and b such that a(1, -1) + b(2, 5) = (-8, -27). Determine the angle between the lines x - y = 3 and 3x + 2y = 11. Determine c if 2i + cj + (c - 2)k and ci + 3j + ck are orthogonal. Determine all vectors orthogonal to both (2, 3, -1) and (1, -2, 2).
