Answer:
![volume = 1536 m^3](https://tex.z-dn.net/?f=volume%20%3D%201536%20m%5E3)
Step-by-step explanation:
given data;
B = 16m
b =8 m
height H = 4 m
length L = 32 m
volume of any right cylinder = (Area of bottom) \times (length)
Volume = A* L
The area of a trapezoid is
![A=\frac{1}{2} H*(b+B)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%20H%2A%28b%2BB%29)
![A =\frac{1}{2} 4*(8+16)](https://tex.z-dn.net/?f=A%20%3D%5Cfrac%7B1%7D%7B2%7D%204%2A%288%2B16%29)
![A = 48 m^2](https://tex.z-dn.net/?f=A%20%3D%2048%20m%5E2)
therefore volume is given as
volume = 48*32
![volume = 1536 m^3](https://tex.z-dn.net/?f=volume%20%3D%201536%20m%5E3)

Answer:
Option B: |x - 27.6| = 5.3
Step-by-step explanation:
We are told that the average time for athletes on the Central High School track team to run 200 meters is 27.6 seconds.
We are also told that the slowest and fastest recorded times varied from the average by 5.3 seconds.
This means that the slowest time varied by 5.3 seconds more than the average while the fastest time varied by 5.3 seconds less than the average.
If x is to represent the slowest or fastest time, the absolute value equation can be written as;
|x - 27.6| = 5.3
No but if u do i’m here to help
Simply solve for x:
-x^2 + 9 = 0 => x = 3 and x = -3;
plug x = 3 and x = -3 into the original equation you get 3 = 3 and -9 = -9, respectively;
So, the two intersecting points are (-3, -9), (3, 3).
And of course, the parabola opens down since its square term is minus.
