Step-by-step explanation:
Answer:
The rational numbers are 
and the irrational functions are 
.
Step-by-step explanation:
A rational number can be expressed in the form of 
, where p and q are integers and q is not equal to 0. For example 
.
An irrational function can not be expressed in the form of , where p and q are integers and q is not equal to 0. For example 
.
If any number is multiplied by a irrational number then the resultant number is an irrational number.
By the above definition we can conclude that:
The number 
is a rational number.
Therefore 
is an irrational number.
Therefore 6.25 is a rational number.
Therefore 0.01045 is a rational number.
The number 
is a rational number.
The number 
is an irrational number.
Therefore 
is an irrational number. The numbers with recursive bar are always rational numbers.

Answer:
<h3>495 different ways</h3>
Step-by-step explanation:
This question bothers on combination. Combination has to do with selection. When selecting r objects from a pool of n objects, this is expressed as;
nCr = n!/(n-r)!r!
For us to choose rank the first 4 choices from 12 students nominated, this can be done in 12C4 number of ways;
12C4 = 12!/(12-4)!4!
12C4 = 12!/8!4!
12C4 = 12*11*10*9*8!/8!*4*3*2
12C4 = 12*11*10*9/24
12C4 = 11880/24
12C4 = 495 ways
Hence this can be done in 495 different ways
