Answer:
A ≈ 22.2 ft²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 7.13² × 
= 50.8369π ×
≈ 22.2 ft² ( to the nearest tenth )
Answer:
Step-by-step explanation:
I used the following points.
x y
-10 -1
-5 -1
-1 0
0 1
1 3
2 7
3 15
From which I think the graph turns out to be y = 2^(x + 1) - 1
-6 2
0 5
1 8
2 14
From which I get y = 3*2^x + 2
You may say to me that's all well and good, but how did you do it? You have to take a few wild guesses. It also helps to know where the question came from. What were you studying when the graphs were assigned?
I don't think there is a magic bullet for figuring these out. You just have to keep on trying until you get it.
One thing is certain. You should work on the y intercept (5) and the distance above or below the x axis. The distance above the x axis is 2 which means that c = 2.
y = a*b^x + c
c is the constant above or below the x axis. You need only read the graph to get the result. a is the hardest to find, but it will be just slightly easier when you let x = 0.
a + c = 5 Since c = 2 a must be 3
Answer:
Step-by-step explanation:
9x+
=x-13
9x*3+1/3=x-13
27x+1/3=x-13
27x+1=3(x-13)
27x+1=3x-39
27x-3x=-39-1
24x=-40
x=-5/3
x=-5/3
I'm pretty sure the answer is SAS because it gives you one angle and the rest are sides
