Suppose that A = PDP-1 . Prove that det(A) = det(D)

daser333 [38]

Answer:

Check.

Step-by-step explanation:

To prove it we need to know that for two matrices A and B we have that:

det(AB) = det(A)*det(B) and $det(A^{-1}) = \frac{1}{det(A)}$ . Now:

$A = PDP^{-1}$

$det(A) = det(PDP^{-1})$

$det(A) = det(P)*det(D)*det(P^{-1})$

$det(A) = det(P)*det(D)*\frac{1}{det(P)}$

$det(A) = det(P)*\frac{1}{det(P)}*det(D)$

$det(A) = det(D)$ .

The lines below are perpendicular. If the slope of the green lines in 3/2, what is the slope of the red line

MakcuM [25]

Answer:

-2/3

Step-by-step explanation:

Where 2 lines are perpendicular, the slope of one = - 1 / slope of the other.

Thus the slope of the red line is - 1 / 3/2

= -2/3
