- Review Exercises Writing a Linear Combination In Exercises 9-12, write v as a linear combination of u1,u2 and u3, if possible. v=(4,4,5),u1=(1,2,3),u2=(2,0,1) and u3=(1,0,0)arrow_forwardWriting a Linear Combination In Exercises 53and 54, use a software program or a graphing utility to write vas a linear combination of u1, u2, u3, u4, and u5. Then verify your solution. v=(5,8,7,2,4)u1=(1,1,1,2,1)u2=(2,1,2,1,1)u3=(1,2,0,1,2)u4=(0,2,0,1,4)u5=(1,1,2,1,2)arrow_forwardWriting a Linear Combination In Exercises 47-50, write v as a linear combination of u1, u2,andu3, if possible. v=(10,1,4),u1=(2,3,5),u2=(1,2,4),u3=(2,2,3)arrow_forward
- Spanning Sets, Linear Independence and Bases. In Exercises 27-32 determine whether the set a spans R3, b is linearly independent, and c is a basis of R3. S={(1,5,4),(11,6,1),(2,3,5)}arrow_forwardTrue or false? In Exercises 63and 64, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text. (a) A set S={v1,v2,...,vk}, k2 is linearly independent if and only if at least one of the vectors vi can be written as linear combination of the other vectors in S. (b) If a subset S spans a vector space V, then every vector in V can be written as a linear combination of the vectors in S.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
- Determining Whether a Set Is a Basis In Exercises 5356, determine whether S is a basis for R3. If it is, write u=(8,3,8) as a linear combination of the vectors in S. S={(23,52,1),(1,32,0),(2,12,6)}arrow_forwardExplaining Why a Set Is Not a BasisIn Exercises 23-30, explain why S is not a basis for P2. S={1,2x,4+x2,5x}arrow_forwardCalculus In Exercises 57-60, let Dx be the linear transformation from C[a,b] into C[a,b] from Example 10. Determine whether each statement is true or false. Explain. Dx(ex2+2x)=Dx(ex2)+2Dx(x)arrow_forward
- Finding the Nullity and Describing the Kernel and Range In Exercises 33-40, let T:R3R3 be a linear transformation. Find the nullity of T and give a geometric description of the kernel and range of T. rank(T)=2arrow_forwardProofProve that if A is not square, then either the row vectors of A or the column vectors of A form a linearly dependent set.arrow_forward
