Find an explicit description of Nul A by listing vectors that span the null space. 1 40 3 0 A=0 01 -3 0 0 0 0 0 -2 A spanning set for Nul A is} (Use a comma to separate answers as needed.)- 10 -4 - 14 Let A = 6 4 10 and w = 1 . Determine if w is in Col(A). Is w in Nul(A)? 2 0 2 Determine if w is in Col(A). Choose the correct answer below. O A. The vector w is not in Col(A) because Ax = w is an inconsistent system. O B. The vector w is in Col(A) because the columns of A span R 3. C. The vector w is in Col(A) because Ax = w is a consistent system. O D. The vector w is not in Col(A) because w is a linear combination of the columns of A. Is w in Nul(A)? Select the correct choice below and fill in the answer box to complete your choice. O A. No, because Aw = O B. Yes, because Aw =4.2.4 Find an explicit description of Nul A by listing vectors that span the null space.
