Area of circle = pi r^2 = 78.54
r^2 = 78.54 / pi = 25
r = 5 inches
Each line from centre of the circle to a point on the hexagon = 5 ins
so consider one of the 6 congruent triangles formed from these lines:-
Vertex angle = 60 degrees
sin 30 = 0.5s / 5 (where s = one side of the hexagon).
0.5s = 5*0.5 = 2.5
s = 2.5 / 0.5 = 5
So the perimeter of the hexagon is 6*5 = 30 inches
Let
x-------> the number of hours
y------> the temperature in degrees Fahrenheit
we know that
For 
For 
The domain of the function is the interval----------> ![[0,30]](https://tex.z-dn.net/?f=%5B0%2C30%5D)
The range of the function is the interval----------> ![[-10,30]](https://tex.z-dn.net/?f=%5B-10%2C30%5D)
therefore
<u>the answer is</u>
The domain is all real numbers 0 through 30
Step-by-step explanation:
Can you put an photo up like what is it from on edge?
Step-by-step explanation:
-t = 9(t-10)
-t = 9t - 90
90 = 9t + t
90 = 10t
90 ÷ 10 = t
9 = t
