Answer:
first option
Step-by-step explanation:
To obtain ( f ○ g)(x) substitute x = g(x) into f(x) , that is
f(
)
=
( multiply numerator/ denominator by 2x to clear the fraction
= ![\frac{2(2x)}{2x(\frac{1}{2x}+3) }](https://tex.z-dn.net/?f=%5Cfrac%7B2%282x%29%7D%7B2x%28%5Cfrac%7B1%7D%7B2x%7D%2B3%29%20%7D)
= ![\frac{4x}{1+6x}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B1%2B6x%7D)
The one on the right is correct. please give brainliest.
Sin = opposite/hypothenuse
Given opposite = 16
Hypothenuse = ?
Use Pythagorean theorem to find hypothenuse
12^2 + 16^2 = h^2
144 + 256 = h^2
h^2 = 400, h = 20
You know hypothenuse is 20
Opposite/hypothenuse
Solution: 16/20
Simplify if you need to (4/5)
