Use a software program or a graphing utility with matrix capabilities to write v as a linear combination of u1, u2, u3, u4, and u5. Then verify your solution. (Enter your answer in terms of u1, u2, u3, u4, and u5.)v = (5, 2, −9, 11, 8) u1 = (1, 2, −3, 4, −1) u2 = (1, 2, 0, 2, 1) u3 = (0, 1, 1, 1, −4) u4 = (2, 1, −1, 2, 1) u5 = (0, 2, 2, −1, −1)
