Hw11p2 (20 points) - the rank a. (2 pts) without calculations, is s = {v1, v2, v3, v4, vs} linearly dependent or independent. b. (8 pts) show that vs can be written as a linear combination of v1, v2, v3 and v4. hint: find the constants c1, c2, and c4 in the equation vs = cv + c2v2 + + cava. c. determine whether t = {v1, v2, v3, v4} is linearly dependent or independent. show this by 2 methods: i. (4 pts) the rank ii. (4 pts) the determinant after reduction to ref. d. (2 pts) what is the span of t.
