Answer:

since the polygon has eight sides, it's an octagon and no, it's not regular since length of all sides of a regular polygon must be equal but in that octagon, not all sides are equal.

Alja [10]

Answer:

150 students

Step-by-step explanation:

60% = 0.6

x + 0.6x = 240

1.6x = 240

x = 240/1.6

x = 150

What is the measure of Arc ED in circle H? 98 POINTS!!

svlad2 [7]

Answer:

90°

Step-by-step explanation:

EG is a straight line

EG = EHD + DHG

DHG is a 90 degree angle

180 = EHD +90

Subtract 90 from each side

180-90= EHD +90-90

90 = EHD

The arc has the same measure as the angle since it is from the center

arc ED = 90

ALGEBRA 1, SEMESTER 2

SIZIF [17.4K]

So firstly, we have to find f(x) when x = 8 and x = 0. Plug the two numbers into the x variable of the function to solve for their f(x):

$f(0)=\frac{2*0+3}{3*0-3}\\ f(0)=\frac{0+3}{0-3}\\ f(0)=\frac{3}{-3}\\ f(0)=-1\\ \\ f(8)=\frac{2*8+3}{3*8-3}\\ f(8)=\frac{16+3}{24-3}\\ f(8)=\frac{19}{21}$

Now that we have their y's, we can use the slope, aka average rate of change, formula, which is $\frac{y_2-y_1}{x_2-x_1}$ . Using what we have, we can solve it as such:

$\frac{\frac{19}{21}-(-1)}{8-0}=\frac{\frac{40}{21}}{8}=\frac{40}{21*8}=\frac{40}{168}=\frac{5}{21}$

In short, the average rate of change from x = 0 to x = 8 is 5/21.
