  1. Make a matrix called A whose first row comprises the numbers 1, 2, 3, ..., 10; whose second row comprises 1, 3, 5, ..., 19; and whose third row is all ones.
  2. Let \(A_k\) denote the \(3\times3\) matrix whose first entry is \(A_{1,k}\) and whose lower-right corner element is \(A_{3,k+2}\), for \(k=1,2,\dots,8\). Find \(A_3\).
  3. Let \(x[1,1,1]^T\). What is \(A_5x?\)
  4. What is \(x^TA_6\)?
  5. What is the rank of A?

A solution for the final is available.
