n = 66
Step-by-step explanation:
you can make a proportion 3/99 = 2/x

99 * 2= 198
3 * x = 3x
so the equation would be 198 = 3x
than do 198 ÷ 3 on ur calculator
so x (or n in this context) would equal 66
Answer:
f-1(x) = 1/3x would be the answer
Step-by-step explanation:
First factor out the 2:
x^2 - y^2 = 36
x^2 - y^2 can be factored into (x+y)(y-y) so:
(x + y)(x - y) = 36
plug in your value:
18 (x-y) = 36 and you should be able to take it from there
Answer with Step-by-step explanation:
We are given S be any set which is countable and nonempty.
We have to prove that their exist a surjection g:N
Surjection: It is also called onto function .When cardinality of domain set is greater than or equal to cardinality of range set then the function is onto
Cardinality of natural numbers set =
( Aleph naught)
There are two cases
1.S is finite nonempty set
2.S is countably infinite set
1.When S is finite set and nonempty set
Then cardinality of set S is any constant number which is less than the cardinality of set of natura number
Therefore, their exist a surjection from N to S.
2.When S is countably infinite set and cardinality with aleph naught
Then cardinality of set S is equal to cardinality of set of natural .Therefore, their exist a surjection from N to S.
Hence, proved
