Express the solution to the recursion nt+1 = ant in terms of the eigenvectors and eigenvalues of a. use de moivre’s theorem to simplify the solution, if appropriate.
a=
[a -1
1 -a]
and n0 =
[1
0], where a is a real number.

Reflect the point (7,0) across the y-axis

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
