In Exercises 35 and 36, find the value of the constant k such that B = A1. 36. A = [ 1 2
Chapter 8, Problem 36(choose chapter or problem)
Finding a Matrix Entry In Exercises 35 and 36, find the value of the constant k such that \(B=A^{-1}\).
\(A=\left[\begin{array}{rr}-1&1\\ 2&1\end{array}\right],\quad\ \ \ B=\left[\begin{array}{rr}-\frac{1}{3}&\frac{1}{3}\\ k&\frac{1}{3}\end{array}\right]\)
Text Transcription:
B = A^-1
A = [ _2 1 ^-1 1], B = [ _k 1/3 ^-1/3 1/3)
