The sum of the angles of an n-sided polygon is (n-2)×180°
For a 30-gon, it would be 28x180 = 5040, answer B
Second question is more of a trick question. Exterior angles always add up to 360. So answer H.
Y = mx + b
<span>mx is the slope, with m being the actual slope and x being there to signify that that is the slope. b is the y-intercept. </span>
<span>-- </span>
<span>y = 4/3x + 8 </span>
<span>In this case, 8 is the y-intercept. Plot a point at (0,8). </span>
<span>4/3 is the slope. After you plotted the y-intercept, go up 4 spaces, then go to the right 3 spaces. </span>
<span>Then draw a line connecting the dots. </span>
Answer:
Composition: 
Domain = {
}
Step-by-step explanation:
Given

The requested composition becomes:

Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:
(so the square root is defined in the Real number system)
This means 
The Domain is then all the Real x-values such that
