M(x) = 5x + 4     n(x) = 6x - 9

Part 1 (m + n)(x) = 5x + 4 + 6x - 9
                           = 11x - 5

Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36

Part 3 m[n(x)] = 5(6x - 9) + 4
                       = 30x - 45 + 4
            = 30x - 41

Graph each circle given below right the center and radius of each circle
expeople1 [14]

Answer:

Center: (-3,-2)

Radius: √6

The graph is attached.

Step-by-step explanation:

The equation of the circle has the form:

(x -h)^{2}+(y-k)^{2}=r^{2}

Where (h,k) is the  point of the center of the circle and r is the radius of the circle.

The equation given in the problem is

(x +3)^{2}+(y+2)^{2}=6

 Therefore:

h=-3

k=-2

The center is at (-3,-2)

And the radius is:

r^2=6\\r=\sqrt{6}

Then, you can graph it has you can see in the image attached.

Use the following graph of the function f(x) = x3 − 3x2 − x + 3 to answer this question: graph of x cubed minus 3 x squared minu
Marina CMI [18]

The average rate of change is also known as the slope. If we are looking to find the average rate of change between x = -1 and x = 2, in order to find the slope between those 2 x values, we need the y's that go along with them. Fill in -1 for x in the function and solve for y: (-1)^3-3(-1)^2-(-1)+3=0. That means that the coordinate is (-1, 0). Fill in 2 for x in the function and solve for y: (2)^3-3(2)^2-(2)+3=-3. The coordinate there is (2, -3). Now we can set up the slope formula to find the average rate of change between those 2 points: \frac{-3-0}{2-(-1)}=\frac{-3}{3}=-1. Therefore, the average rate of change between x = -1 and x = 2 is -1
