- Use a software program or a graphing utility to write v as a linear combination of u1, u2, u3, u4, u5 and u6. Then verify your solution. v=(10,30,13,14,7,27) u1=(1,2,3,4,1,2) u2=(1,2,1,1,2,1) u3=(0,2,1,2,1,1) u4=(1,0,3,4,1,2) u5=(1,2,1,1,2,3) u6=(3,2,1,2,3,0)arrow_forwardVector Operations In Exercises 2932, find a uv, b 2(u+3v), c 2vu. u=(6,5,4,3),v=(2,53,43,1)arrow_forwardWriting a Linear Combination In Exercises 4750, write v as a linear combination of u1, u2,and u3, if possible. v=(1,7,2),u1=(1,3,5),u2=(2,1,3),u3=(3,2,4)arrow_forward
- Review Exercises Writing a Linear Combination In Exercises 9-12, write v as a linear combination of u1,u2 and u3, if possible. v=(3,0,6),u1=(1,1,2),u2=(2,4,2) and u3=(1,2,4)arrow_forwardProof Prove that u+v=u+v if and only if u and v have the same direction.arrow_forwardTake this test to review the material in Chapters 4and Chapters 5. After you are finished, check your work against the answers in the back of the book. Write w=(7,2,4) as a linear combination of the vectors v1, v2 and v3 if possible. v1=(2,1,0), v2=(1,1,0), v3=(0,0,6)arrow_forward
- Vector Operations In Exercises 33and 34, use a graphing utility to perform each operation where u=(1,2,-3,1), v=(0,2,-1,-2), and w=(2,-2,1,3). (a) v+3w (b) 2w12u (c) 12(4v3u+w)arrow_forwardProof Let S={u,v} be a linearly independent set. Prove that the set {u+v,uv} is linearly independent.arrow_forwardProof When the set of vectors {u1,u2,...,un} is linearly independent and the set {u1,u2,...,un,v} is linearly dependent, prove that v is the linear combination of the uis.arrow_forward
