Answer:
the answer is 1/12
Step-by-step explanation:
you have to rewrite the problem
it would be 1/4 divided by 3
then it would be 1/4 multiplied by 1/3
then you multiply and get your answer of 1/12
Answer:
![(rs)(4) = 8](https://tex.z-dn.net/?f=%28rs%29%284%29%20%3D%208)
Step-by-step explanation:
Given
![r(x) = 2\sqrt{x](https://tex.z-dn.net/?f=r%28x%29%20%3D%202%5Csqrt%7Bx)
![s(x) = \sqrt x](https://tex.z-dn.net/?f=s%28x%29%20%3D%20%5Csqrt%20x)
Required
Determine ![(rs)(4)](https://tex.z-dn.net/?f=%28rs%29%284%29)
In functions:
![(fg)(x) = f(x) * g(x)](https://tex.z-dn.net/?f=%28fg%29%28x%29%20%3D%20f%28x%29%20%2A%20g%28x%29)
This implies that:
![(rs)(x) = r(x) * s(x)](https://tex.z-dn.net/?f=%28rs%29%28x%29%20%3D%20r%28x%29%20%2A%20s%28x%29)
Substitute values for r(x) and s(x)
![(rs)(x) = 2\sqrt{x} * \sqrt{x}](https://tex.z-dn.net/?f=%28rs%29%28x%29%20%3D%202%5Csqrt%7Bx%7D%20%2A%20%5Csqrt%7Bx%7D)
![(rs)(x) = 2(\sqrt{x})^2](https://tex.z-dn.net/?f=%28rs%29%28x%29%20%3D%202%28%5Csqrt%7Bx%7D%29%5E2)
![(rs)(x) = 2x](https://tex.z-dn.net/?f=%28rs%29%28x%29%20%3D%202x)
Substitute 4 for x
![(rs)(4) = 2 * 4](https://tex.z-dn.net/?f=%28rs%29%284%29%20%3D%202%20%2A%204)
![(rs)(4) = 8](https://tex.z-dn.net/?f=%28rs%29%284%29%20%3D%208)
