Use the Well-Ordering Principle of the natural numbers to
prove that every positive
rational number x can be expressed as a fraction x = a/b where
a and b are postive
integers with no common factor.
Use the well-ordering property to prove the division algorithm.
Recall that the division algorithm states that if a is an integer
and d is a positive integer, then there are unique integers q and r
with 0 ≤ r < d and a = dq + r.
State and prove a generalized version of pigeonhole principle
and use it to prove the following statement: If 22 numbers are
selected at random, at least 4 of them will have the same remainder
when divided by 7.
1. Prove that √ 5 is not a rational number and Is it true that √
n is not a rational number for any positive integer n? Explain and
show proof of in the answer and show work please.

Describe briefly the principle of the Rational method and the
limitation of this method for runoff estimation. A sub-catchment of
area 0.1km2 is built on gently sloping land. The average
slope of the land is 0.001. The length of the longest natural flow
path L is 276.3m. The flow time tf in the drainage
system is 3min. Determine the 50yr design discharge for the
subdivision using the rational method, given that the average
runoff coefficient of the subdivision is C=0.7....
