For any fixed tЄR, find det(A(t)).
Show that the matrix A(t) is invertible for any tЄ R, and find the
inverse (A(t))¹.
Use the infinite geometric sum to convert .258 (the 58 is recurring, so there is a bar over it) to a ratio of two integers. Please go over the full problem, specifying how you found r. Thank you.
