I think 517.26
I did 10 times 3^2 (9) it equals 90. Then 90 times 3.14 and got 282.74. Then did 800- 282.74 and got 517.26
Suppose that the <u>function</u> f(x) is the <u>parrent</u> function and the<u> graph</u> of the function g(x)=f(x)-a can be obtained from the graph of the parrent function f(x) by <u>shifting down</u> a units.
Rewrite the expression for the function
in the following way:
![g(x)=32x-9=32x+8-8-9=32x+8-17=f(x)-17.](https://tex.z-dn.net/?f=g%28x%29%3D32x-9%3D32x%2B8-8-9%3D32x%2B8-17%3Df%28x%29-17.)
This shows that the shift down is made by 17 units.
Answer: 17 units
Each piece = (4/5) yards
(4/5) yards * 3 feet = 2.4 feet each piece
which equals 2 feet 4.8 inches each
The triangles are isosceles. The following notation are for the angles. For example ABD is refer to the angle located in the B vertex, formed by the segments AB and BD.
![ABD = ADB\\40 + 2ADB = 180\\ADB = 70 = ABD\\](https://tex.z-dn.net/?f=ABD%20%3D%20ADB%5C%5C40%20%2B%202ADB%20%3D%20180%5C%5CADB%20%3D%2070%20%3D%20ABD%5C%5C)
![70 + DBC + 30 = 180\\DBC = 180 - 100 = 80](https://tex.z-dn.net/?f=70%20%2B%20%20DBC%20%2B%2030%20%3D%20180%5C%5CDBC%20%3D%20180%20-%20100%20%3D%2080)
Then
![BCD = BCD\\2BCD + 80 = 180\\BCD = 50](https://tex.z-dn.net/?f=BCD%20%3D%20BCD%5C%5C2BCD%20%2B%2080%20%3D%20180%5C%5CBCD%20%3D%2050)
