Answer:
Area of nonagon = 1044.6 square millimetres.
Step-by-step explanation:
Let side of the nonagon is a
Given:
The perimeter of nonagon is 117 millimetres
![perimeter=9a](https://tex.z-dn.net/?f=perimeter%3D9a)
Put the perimeter value in above equation
![a=\frac{117}{9}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B117%7D%7B9%7D)
![a=13](https://tex.z-dn.net/?f=a%3D13)
So the side of the nonagon is 13
The area of the nonagon is .
![A=\frac{9}{4} a^{2} cot(\frac{180}{9})](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B9%7D%7B4%7D%20a%5E%7B2%7D%20cot%28%5Cfrac%7B180%7D%7B9%7D%29)
where a is side of the nonagon.
Put value of side in above equation
![A=\frac{9}{4} 13^{2} cot(20)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B9%7D%7B4%7D%2013%5E%7B2%7D%20cot%2820%29)
![A=\frac{9\times 169}{4}\times 2.747}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B9%5Ctimes%20169%7D%7B4%7D%5Ctimes%202.747%7D)
![A=\frac{1521}{4}\times 2.747}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1521%7D%7B4%7D%5Ctimes%202.747%7D)
![A=380.25\times 2.747}](https://tex.z-dn.net/?f=A%3D380.25%5Ctimes%202.747%7D)
![A=1044.55](https://tex.z-dn.net/?f=A%3D1044.55)
Therefore, the area of the nonagon is 1044.6 square millimetre.
Answer:(-5,1)(2,2)
Step-by-step explanation:
distribute the -1 and 2
(-5,1) (2,2)
Answer: 0.40a + 0.40b
Step-by-step explanation:
Total Profit
= P(a,b) = ($0.40a) + ($0.40b),
where a = no. of apples sold and b = no. of bananas sold.
FOR THE FIRST BLANK:
The third box is the answer
Domain: {-3, -1, 1, 4}
Range: {-4, -1, 1, 4}
The domain is the x values of each point and the range is the y values of each point. You always state the domain and range from smallest to largest.
FOR THE SECOND BLANK:
The second box is the answer
Domain: {-4, -3, 1)
Range: {1, 3, 4}
Again, look at the x values to find the domain and the y values to find the range.
Keep in mind that if a number repeats itself, you only include it once.
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 5 ← is in slope- intercept form
with slope m = 2 and y- intercept c = 5
