Answer the following questions related to the Rank Theorem and the Rank and Nullity Theorem: a) Suppose A is a 5×7 matrix If A has rank 3, then rank(AT) = 0 b) Suppose A is a 4×6 matrix If A has rank 3, then dim(col(A)) = 0 c) Suppose A is a 5×7 matrix If dim(null(A)) = 4, then dim(row(A)) = 0 d) Suppose A is a 4×6 matrix If dim(row(A)) = 2, then dim(col(A)) = 0 e) Suppose A is a 4×5 matrix The smallest value dim(null(A)) could possibly have is 0
