Use the given matrices to find the expression. 9 7 7 C = |1 8 9 ; C- (A + I) 2 8 7 3 8 2 A = |8 9 3 6 2 8 C - (A + I) =

Explain what is meant by the minor of an entry in a square matrix.

Determine if the statement is true or false. If the statement is false, then correct it and make it true. For the product of two matrices to be defined, the number of rows of the first matrix must equal the number of columns of the second matrix.

We can add (or subtract) two matrices only if they have the same ______.

Use an example chosen from 22 matrices to show that for nn matrices A and B,ABBA but AB=BA.

Can a matrix with zeros on the diagonal have an inverse? If so, find an example. If not, prove why not. For simplicity, assume a 22 matrix.

Find an orthogonal matrix whose first row is (1/3,2/3,2/3)

Compute each matrix sum or product if it is defined. If an expression is undefined, explain why. Let A = 6 -5 2 35 --[; : -]-[-²]-[-²]-~--[¯†1] B= D= 1 -3 -2 3 A + 3B, 4C-2E, DB, EB -4 23 OA. A+3B= 2 and E= -4 3 1 0-3 [:] 4-6 2 Compute the matrix sum A + 3B. Select the correct choice below and, if necessary, fill in the answer box within your choice. (Simplify your answer.) O B. The expression A+ 3B is undefined because A is not a square matrix. O C. The expression A+ 3B is undefined because A and 3B have different sizes. O D. The expression A+ 3B is undefined because B is not a square matrix.

The sequence of numbers we’re generating are traditionally constructedlike this: Start with the first 2 numbers. To get the next number, take the 2most recent numbers and add them together to get the next one.Explain why our matrix vector multiplication is generating the same numbersas the traditional procedure.
