Answer:

Circumference = 2 x pi x r

Radius, r = 7/2

Circumference = 2 x 22/7 x 7/2

= 22 cm

Which ordered pair is included in the solution set to the following system? y > x2 + 3 y < x2 – 3x + 2 (–2, 8) (0, 2) (0,

I am Lyosha [343]

The ordered pair that is a solution of the system is (-2, 8).

<h3>Which ordered pair is included in the solution set to the following system?</h3>

Here we have the system of inequalities:

y > x² + 3

y < x² - 3x + 2

To check which points are solutions of the system, we can just evaluate both inequalities in the given points and see if they are true.

For example, for the first point (-2, 8) if we evaluate it in the two inequalities we get:

8 > (-2)² + 3 = 7

8 < (-2)² - 3*(-2) + 2 = 12

As we can see, both inequalities are true. So we conclude that (-2, 8) is the solution.

(if you use any other of the 3 points you will see that at least one of the inequalities becomes false).

Which one of these graphs does not illustrate a function? And why

Svetach [21]

Answer:

It would be <em>Graph D</em>

<em />

Step-by-step explanation:

It's graph D because according to the graph, it looks like the domain has 2 ranges since it made a vertical line. And as we know, vertical lines are not considered to be functional since a domain can't have more than one range.

The image below is a triangle drawn inside a circle with center O:

Alex17521 [72]

The area of a circle is,

$\pi \: \times r ^{2}$

So pi times the radius squared.

~~

To find the radius we half to divide the diameter by 2 since the radius is half of the diameter.

The diameter is the line that passes through the the center of the circle going from one side of the circle to the other which is 4 in this case.

Half of 4 is 2 meaning 2 is our radius.

~~

Plug in the numbers and get,

$3.14 \times 2^{2}$

~~
