- Find a basis for R2 that includes the vector (2,2).arrow_forwardTake this test to review the material in Chapters 4 and 5. After you are finished, check your work against the answers in the back of the book. Prove that the set of all singular 33 matrices is not a vector space.arrow_forward3. Determine whether the vectors are linearly independent or are linearly dependent in P. 1+3x+3x2, x+4x2, 5+ 6xr + 3x2, 7+ 2x-x² IAarrow_forward
- M2arrow_forward5. Determine if the vectors x² + x, 2x²,2x − 3, 9 in P3 are linearly independent or linearly dependent. Do these vectors span P3 ? Explain.arrow_forwardConsider the set S: Is this set a basis for R2? Why or why not? What can be said about how can be represented as a linear combiation of the vectors of S? Explain your answer.arrow_forward
- Determine which pairs of vectors in Exercises 15–18 are orthogonal.arrow_forwardThe following question is from linear algebra : Factors the vector (6, -5, -1)t into three components a,b,c that satisfy the following conditions: a depends on (2,0,1)t, b depends on (1,2, 0)t and c is orthogonal to a and b. Please show it step by step.arrow_forwardThe following question is from linear algebra first year: Factors the vector (6, -5, -1)t into three components a,b,c that satisfy the following conditions: a depends on (2,0,1)t, b depends on (1,2, 0)t and c is orthogonal to a and b. Please show it step by step. Can we get integers as answers?arrow_forward
- 2. Let a, b, č, and d be algebraic vectors in R. For parts (a) and (b) below, state which theorems and definitions from the textbook you use when you use them. (a) Prove that if a 0, then a- 0. (b) Prove that if (a +b+c+d) ) (a-6+e-d)=0, then a + e= ||b + d||. .arrow_forwardExercise 8.1.2 In each case, write x as the sum of a vector in U and a vector in U+. d. x=(2, 0, 1, 6), U = span {(1, 1, 1, 1), (1, 1, −1, −1), (1, −1, 1, −1)}arrow_forwardShow your work with good explanation.arrow_forward
