400,000 milligrams because 1 gram is 1000 milligram.
Answer:
A
Step-by-step explanation:
So we have the two functions:
![f(x)=x^2-1\\g(x)=\sqrt x](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2-1%5C%5Cg%28x%29%3D%5Csqrt%20x)
And we want to find:
![(f\circ g)(1)](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%281%29)
This is the same as:
![f(g(1))](https://tex.z-dn.net/?f=f%28g%281%29%29)
So, to find the answer, find g(1) first:
![g(x)=\sqrt x\\g(1)=\sqrt1\\g(1)=1](https://tex.z-dn.net/?f=g%28x%29%3D%5Csqrt%20x%5C%5Cg%281%29%3D%5Csqrt1%5C%5Cg%281%29%3D1)
Now, substitute this value for g(1):
![f(g(1))\\=f(1)](https://tex.z-dn.net/?f=f%28g%281%29%29%5C%5C%3Df%281%29)
And plug this into f(x):
![f(x)=x^2-1\\f(1)=(1)^2-1\\f(1)=1-1=0](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2-1%5C%5Cf%281%29%3D%281%29%5E2-1%5C%5Cf%281%29%3D1-1%3D0)
Therefore:
![f(1)=f(g(1))=(f\circ g)(1)=0](https://tex.z-dn.net/?f=f%281%29%3Df%28g%281%29%29%3D%28f%5Ccirc%20g%29%281%29%3D0)
Our answer is A

If you put 5 which means its 2 1/2 ( I think) Because two 1/2 makes one.
Are you cheating in a exam if you are
