Correct composition of ( f o g)(1) is option A i.e. (ƒ ∘ g)(1) = 49
<h3>What are functions ?</h3>
- In mathematics, a function from a set X to a set Y assigns exactly one element of Y to each element of X.
- The sets X and Y are referred to together as the function's domain and codomain, respectively.
- A function connects an input with an output.
- It works like a machine, having an input and an output.
- Furthermore, the input and output are linked in some way.
<h3>Calculation </h3>
f(x) = 5
– x + 1
g(x) = -3x
a) ( f o g )(1) = 49
f(g(1)) = 49
5 * -
- (-3) + 1 = 45 +3+1 = 49
it is true
all the other options are not equal to the given answer .

The answer is A :)
Step-by-step explanation:
Answer:
First you Set up a ratio where your large side is on top of the fraction and the smaller side is on the bottom of the fraction. Then you Divide the ratio, then set the bottom number to one.
Answer:
x=40
Step-by-step explanation:
so the angle opposite the 20º angle must also be 20º
this means that because 20º and 2 2x's are all on one straight line they must add up to 180
so 180=20+2*2x
160=4x
x=40
