Web(c) The nullity of a nonzero matrix is at most m. Answer: False (d) Adding one additional column to a matrix increases its rank by one. Answer: False (e) The nullity of a square matrix with linearly dependent rows is at least one. Answer: True (f) If A is square and is inconsistent for some vector , then the nullity of A is zero. Answer: False WebIt turns out that the Rank-Nullity Theorem holds this answer. If D is an m n matrix, then DTD is an n n matrix.
