Answer:
<h2>MN = 9.1 cm</h2>
Step-by-step explanation:
If MN is tangent of a circle then the angle M is a right angle.
We have a dimeter of acircle d = 8 cm.
Therefore the radius CM = 8 cm : 2 = 4cm.
In a right triangle CMN use the Pythagorean theorem:

Substitute CM = 4cm and CN = 9.9 cm:

<em>subtract 16 from both sides</em>

What does that mean I don't get it I will randomly guess 500000000
Answer:
All values along the x-axis in the shaded regions.
Step-by-step explanation:
The solution set of the compound inequality is any number less than 2 and greater than 7. This means its all the numbers on the number line from 1.99999 to 0 to -9 to -1000 and so forth. And it's also any number greater than 7 including 7.01 to 1000 to 1,000,000. See the graph below to visually see the solution. The solution are all the numbers along the x-axis in the shaded regions.
Answer:
