- 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_forwardCompute the products in Exercises 1–4 using (a) the definition, as in Example 1, and (b) the row–vector rules for computer Ax, or, the rule for computing a product Ax in which the i th entry of Ax is the sum of the products of corresponding entries from row i of A and from the vector x. If a product is undefined, explain why.arrow_forward
- Can any of the given sets of 3-vectors below span the 3-space? Why or why not? (a) [121] [231] [342]arrow_forwardPlease solve only question a in complete English sentence.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
- (Section 5.3) 3. a. i. Show that the vectors v₁ = (1, 2, 3, 4), №₂ = (0, 1, 0, −1), and √3 = (1,3,3,3) form a linearly dependent set in IR". b. ii. Express each vector in part i. as a linear combination of the other two. Prove that if {v₁, 02, 03} is a linearly independent set of vectors, then so are {vi, v3), and {₂}.arrow_forwardPlease solve this linear algebra problem with a good explanation.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
