Answer:
![L_c=25.12ft](https://tex.z-dn.net/?f=L_c%3D25.12ft)
Step-by-step explanation:
From the question we are told that
Width of circular path ![w_c=4ft](https://tex.z-dn.net/?f=w_c%3D4ft)
Inner Diameter ![d_i_n=550ft](https://tex.z-dn.net/?f=d_i_n%3D550ft)
Outer diameter
(inner diameter + 2 circular path width)
![d_{out}= 550 +8\\d_{out}= 558ft](https://tex.z-dn.net/?f=d_%7Bout%7D%3D%20550%20%2B8%5C%5Cd_%7Bout%7D%3D%20558ft)
Generally the equation for inner circumference of the circle
is mathematically given by
![C_1=\pi d_{in}](https://tex.z-dn.net/?f=C_1%3D%5Cpi%20d_%7Bin%7D)
![C_1=3.14*550](https://tex.z-dn.net/?f=C_1%3D3.14%2A550)
![C_1=1727ft](https://tex.z-dn.net/?f=C_1%3D1727ft)
Generally the equation for outer circumference of the circle
is mathematically given by
![C_2=\pi d_{out}](https://tex.z-dn.net/?f=C_2%3D%5Cpi%20d_%7Bout%7D)
![C_2=3.14*558](https://tex.z-dn.net/?f=C_2%3D3.14%2A558)
![C_2=1752.12ft](https://tex.z-dn.net/?f=C_2%3D1752.12ft)
Generally the difference in length of the two circumference
is mathematically given by
![L_c=C_2-C_1](https://tex.z-dn.net/?f=L_c%3DC_2-C_1)
![L_c=1752.12-1727](https://tex.z-dn.net/?f=L_c%3D1752.12-1727)
![L_c=25.12ft](https://tex.z-dn.net/?f=L_c%3D25.12ft)
Because the nonagon is regular, the angles are equal. Nona means nine. The total of the measures of the interior angles of any polygon is (n-2)180. Use this formula to find the measure of one interior angle.
(9-2)180
7*180=1260. Divide by 9 to get the measure of one angle.
1260/9=140
The answer is 140 :)
Answer:
Step-by-step explanation:
Given that:
R(x) =
+ 34x − 17
As we know that derivative of revenue function is marginal revenue function .
We will use following rules of derivative
=> dR/ dx =
=> R' (x) =
=> R '(2000) =
= 34
The revenue when 2000 units are sold is:
R(2000) =
+ 34*2000 − 17 = $69,783
