You write your own matrices by changing the numbers written in these matrices and calculate the following operation for these matrices: 1 AT --B + B. C 2 14 91 [1 A = 5 -2 B = 4 9 ,C = |-8 1 Lo -4. 12 -6 1. 1 AT Find the result of the operation. --B + B. Carrow_forwardUse A−1 to decode the cryptogram.arrow_forward
- Encode the message "CRYPTOGRAPHY" using matrix A. Remember to partition the numerical message into groups of two. A = 12 1 3 The coded message is: ...arrow_forwardSolve for A: You can resize a matrix (when appropriate) by clicking and dragging the bottom-right corner of the matrix. 10 2 8 -8 1 7 7 1 8 -9 -6 -8 50 5 8 A = 000 000 000 +AT = -2 -2 0 6 -8 -7 9 -8 -7 5 -7 5 -9 2 -3 -2 -5arrow_forwardUse application of matrix operationarrow_forward
