For example (1,2,3,4),(5,6,7,8) (b) What is the dimension of the row space of A? (c) What is the dimension of the solution space of A? -9 1 (d) Let v a where a € R. Find the value of -3 a such that v is in the solution space of A. a = = =
(2 points) A square matrix A is idempotent if A² = A. Let H be the set of all 2 × 2 idempotent matrices with real entries. Complete the following statements to determine if H is a subspace of M2,2. (a) His If it is non-empty, enter a matrix M E H below. If it is empty, then leave it blank. M = (b) His under vector addition If it is not closed, enter two matrices A, B ¤ H below whose sum is not in H. If it is closed, then leave it blank. A and B = (c) His under scalar multiplication If it is not closed, enter a scalar k and matrix C E H below whose product is not in H. If it is closed, then leave it blank. k = and C= (d) H || of M2,2-
