Grade 12 Matrices CCSS: HSN-VM.C.10
Given a matrix A, is there always another matrix, B, such that their sum is the zero matrix? What are the elements of the matrix B?
  1. No, there isn't always such a matrix B. If there is, its elements are the negative of the corresponding elements in matrix A.
  2. No, there isn't always such a matrix B. If there is, its elements are determined on a case-by-case basis, with no general rule.
  3. Yes, there is always such a matrix. The elements of B are found on a case-by-case basis, with no general rule.
  4. Yes, there is always such a matrix. The elements of B are the negative of the corresponding elements in A.

Grade 10 Business Technology
Which statement best defines a composite matrix? A matrix is
  1. a viscous material that hardens to give shape to the composite part and helps fibers to carry the load.
  2. a synthetic fiber that, when bound together with other fibers, gives the composite strength and stiffness.
  3. a plant resin that has been molded and hardened into its final for of epoxy.
  4. an organic plastic used to give shape to composite fibers and protect them from damage.

If A is a given square matrix, and it is known that there exists a matrix B such that AB=1, which of the following would be the most efficient ways to find the matrix B?
  1. Find the inverse of A. This is the matrix B.
  2. Find the transpose of A. This is the matrix B.
  3. Create a matrix B whose elements are variables. Then, perform matrix multiplication with the matrix A, setting each resulting entry equal to one. Solve this system of equations, which will give the elements of matrix B.
  4. Multiply both sides of the equation, on the left, by slight variations of the matrix A. When one of these matrices, multiplied by A, becomes the identity matrix, this is the matrix B.

What is the rule for matrix multiplication?
  1. The number of columns of the first matrix must equal the number of rows of the second matrix.
  2. The matrices must have the same dimensions.
  3. The matrices must have the same number of rows, but not columns.
  4. There is no rule. Matrix multiplication is always possible.
