Find p-1, where p = [adg beh cfi] is orthogonal.

 The required inverse of the given matrix is

Step-by-step explanation:  We are given to find the inverse of the following orthogonal matrix :

We know that

if M is an orthogonal matrix, then the inverse matrix of M is the transpose of M.

That is,

The transpose of the given matrix P is given by

Therefore, according to the definition of an orthogonal matrix, the inverse of matrix P is given by

Thus, the required inverse of the given matrix is

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
