7.) the equation of the circle is
(x - 3)^2 + (y - 4)^2 = 25

If you substitute the point in you get
(6-3)^2 + (8-4)^2 = 25
3^2 + 4^2 = 25
9 + 16 = 25
25 = 25

Both sides of the equation are the same so it proves it lies on the circle

8.) you add the x coordinates together and divide by 2
7 + 4 = 11
11/2 = 5.5
You use +7 because you need to find the midpoint.
You then add 5.5 to - 7 or - 5.5 from 4
-7 + 5.5 = - 1.5

You do the same for y coordinates
6+5 = 11
11/2 = 5.5
6-5.5 = 0.5

So the coordinates of Rachel's house are
(-1.5, 0.5)

Type the correct answer in each box. find the cofactors of each entry in the first row of the matrix . ac11 = ac12 = ac13 =
natima [27]

The cofactors of each entry in the first row of the matrix are

Ac_11 = -13

Ac_12 = 44

Ac_13 = 27

We have to determine the cofactors of each entry in the first row of the matrix.

Therefore the cofactors of each entry in the first row of the matrix are

Ac_11 = -13

Ac_12 = 44

Ac_13 = 27.

A set of numbers is arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.

Machines had to find a way to cut themselves off from the truth in order to understand humans. Neo's sole purpose in the Matrix is ​​to prevent machines from evolving into dinosaurs.

andrew-mc [135]

Step-by-step explanation:

By Law of Indices, (a^m)^n = a^(mn).

Hence (h²)^(-3) = h^(-6) or 1/h⁶.
