Joe is at most 20 and Bill would be at most 27 because it has to be less than 49 combined
Answer:
Substitute the given n-values into each function, f(n), to determine which generates the same values as the given a(n)'s.
Step-by-step explanation:
Joe is trying to find out how many cubic centimeters of sand he can fit in a hole he dug in his backyard. The size of the hole is shown in the diagram. Which of the equations will yield the correct answer?
The correct answer is :
A) V = 9.1(2.2)(3.8)
Hope this helps!
We have the following function:
![g(x)=4\sqrt{x}-8](https://tex.z-dn.net/?f=g%28x%29%3D4%5Csqrt%7Bx%7D-8)
So if we graph this function we will get the Figure below. Thus, let's study both the equation and the graph to get some conclusions. Therefore, we can assure these statements:
First. The function is defined only for
![x\geq 0](https://tex.z-dn.net/?f=x%5Cgeq%200%20)
as shown in the Figure. This is also true because of
![\sqrt{x}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D)
where
![x](https://tex.z-dn.net/?f=x)
must be greater (or equal) than zero.
Second. The range of the function are the values of
![y\geq -8](https://tex.z-dn.net/?f=y%5Cgeq%20-8)
.
Third. If
![x](https://tex.z-dn.net/?f=x)
creases then
![y](https://tex.z-dn.net/?f=y)
always creases, too.
