(1 point) Let U1, U2, U3 be the vectors in R defined by -8-9-8 (a) Is (U1, U2, U3) linearly independent? Write all zeros if it is or if it is linearly dependent write zero as a non-trivial (not all zero coefficients) linear combination of U1, U2, and U3 0 = U+ U+ V3 (b) Is (U2, 3} linearly independent? Write all zeros if it is or if it is linearly dependent write zero as a non-trivial (not all zero coefficients) linear combination of U2 and 03. (c) Type the dimension of span{U1, U2, 3}: 0 = U+ U3
