The rate of change is -5/4
I find it best to use the Slope formula
M= y2-y1/x2-x1
So we to use need any 2 points on the graph (I used the first 2)
•(0,200) and (80,100)
Now we set up the problem 100-200/80-0
Then you’ll subtract and should get
-100/80
Now you’ll simplify and once you’re done simplifying your answer should be -5/4.
Here is my work. Hope this Helps!
Since the triangle will be a 30-60-90, because 360°/6 = 60° for each central angle, then that is bisected to find the height of each of the 6 equilateral triangles. This height is the same as the apothem.
In a 30-60-90 triangle, the sides are is the ratio of:

where x is opposite the 30° and 2x is opposite the 90°
Since the base is 10 and the hypotenuse is 10, 1/2 that is 5 (the x), and so:

So rounded up, you apothem then is closest to D) 9 in.
Answer:
P = 4x + 22
Step-by-step explanation:
Formula
Perimeter = 2*L + 2*W
Givens
L = x + 6
W = x + 5
Solution
Perimeter = 2*(x + 6) + 2*(x + 5) Remove the brackets on both terms
Perimeter = 2x + 12 + 2x + 10 Collect like terms
Perimeter = 4x + 22 Answer
Answer: 2(x+1)
