Answer: In Exercises 197199, use A1 to decode the cryptogram. 197. A = [ 1 1 1 0 2 2 1 0
Chapter 8, Problem 199(choose chapter or problem)
In Exercises 197–199, use \(A^{-1}\) to decode the cryptogram.
\(A=\left[\begin{array}{rrr} 1 & -1 & 0 \\ 0 & 1 & 2 \\ 1 & 1 & -2 \end{array}\right]\)
21 −11 14 29 −11 −18 32 −6 −26 31 −19
−12 10 6 26 13 −11 −2 37 28 −8 5 13 36
Text Transcription:
A^-1
A = [1 -1 0 0 1 2 1 1 -2]
