Answer:
hey so um what is this question
Answer:
⇒When the funtion is both one one and onto , then inverse of the function exists.
⇒≡Consider the function
y=x+2
It is one-one, because for every x there is unique y.So, it is one one.In one-one, there may be some elements in x, which do not have preimage.
It is onto also, because for each x, there is unique y.
So, the inverse of function will be
x=y-2
Replacing x by y and y by x , gives inverse of the function.
y=x-2, is the inverse of the function.

Step-by-step explanation:
1 1 1
21 x 18 x 13 = 4914
16 x (18x13) = 3744

Step-by-step explanation:
sorry if it's wrong
All I know is that your need to add 15+15 and find the radius of the circle
you all have to fine the circumeference =2 pi r, the area= pi R square
the Radius is 5ft=25ft cuz of the pi r square is 2, pi = 3.14 (value) 3.14*25ft =75 square ft shouled be your answer
