1. N=x+3
S=2(x+3), or Sam=2x+6
You find the circumference of a full circle so 2πr =43.98
then divide by 4=10.995
so the answer is 10.995cm
Answer:

Step-by-step explanation:

Answer:
( 1/3, 5 2/3) Or (0.33, 5.66)
Step-by-step explanation:
If you graph the 2 equations and see where they intersect, they will land on the answer.
The domain and inverse of the function
is
Domain =
,

What is a function?
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
The given function is

r(x) is not defined if x - 4 = 0
r(x) is not defined for x = 4
Domain =
,
Where
is the set of all real number
Let r(x) = y
