Part II: Application For this problem, you will be applying your knowledge of matrix multiplication and inverses. A cryptogram is a message written according to a secret code. For this particular cryptogram, we assign numbers to letters and characters as follows. 0- 12-L 24-X 1-A 13-M 25-Y 2-B 14-N 26-Z 3-C 15-0 27- 4-D 16-P 28- 5-E 17-Q 29- 6-F 18-R 30-1 7-G 19-S 31: 8-H 20-T 32-- 9-1 21-U 33-- 10-J 22-V 34-7 11-K 23-W 35-1 Suppose that you received the following numerical information via a top secret transmission. (a) [67 118-47] (b) [41 79-57] (c) [81 159 -117] (d) [59 97 -15] (e) [47 85-39] (f) [58 109-65] (8) [131 261-208] [1 1 2 Suppose also that you were sent the coding matrix A = 2 4 -3. The coding matrix can 3 6 be thought of as the "key" to unlock the message. Use the coding matrix along with the given numerical information (a-g), and follow the process in Section 6.1 of your book to decode the message. Be sure to include the decoded message. Include ALL work and show the steps taken to decode the message.
