Answer:
405
Step-by-step explanation:
So he built 5/9 of the wall, than added the extra 180 bricks to finish the wall.
so 5/9 + 180 = 9/9
so 180 = 4/9 Because 5/9 + 4/9 = 9/9
So to figure out how many bricks are in the wall we want to know what 1/9 of bricks equals and to work this out we need to divide 180 by 4
which equals 45.
Now we know that 1/9 = 45
so now to figure out what 9/9 is just multiply 45 by 9 which equals 405

Answer:
The value of f(-2) is 1/2 or it can be written as 0.5.
Step-by-step explanation:
The given function is
![f(x)=2\cdot 2^x](https://tex.z-dn.net/?f=f%28x%29%3D2%5Ccdot%202%5Ex)
We have to find the value of f(-2).
Substitute x=-2 in the given function to find the value of f(-2).
![f(-2)=2\cdot 2^(-2)](https://tex.z-dn.net/?f=f%28-2%29%3D2%5Ccdot%202%5E%28-2%29)
![f(-2)=2\cdot \frac{1}{2^(2)}](https://tex.z-dn.net/?f=f%28-2%29%3D2%5Ccdot%20%5Cfrac%7B1%7D%7B2%5E%282%29%7D)
![f(-2)=\frac{1}{2}](https://tex.z-dn.net/?f=f%28-2%29%3D%5Cfrac%7B1%7D%7B2%7D)
![f(-2)=0.5](https://tex.z-dn.net/?f=f%28-2%29%3D0.5)
Therefore the value of f(-2) is 1/2 or it can be written as 0.5.
