Find the characteristic polynomial and the eigenvalues of the following matrix. If the matrix is diagonalizable, find the diagonalization, i. e., find an invertible matrix P and a diagonal matrix D such that A = PDP-1. (Note: you don't need to compute P-1). A = [1 7 -5 -3 11 -5 -3 7 -1]

When only separate discreet points are graphed it is called?

The measure of an angle is 117°. what is the measure of a supplementary angle?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
