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.

Step-by-step explanation:
Divide the hexagon into triangles, for example, as in the diagram below.
The triangles are all inside the hexagon, so the sum of their interior angles is the sum of those of the hexagon.
The sum of the interior angles of a triangle is 180°.
There are four triangles, so
Sum of interior angles = 4 × 180° = 720°
We know the width of the rectangle in the middle of the trapezoid is 24 (from the top of the image), so we can subtract that from the bottom width of the trapezoid to get the combined length of the bottom of both triangles.
Since this is an isosceles trapezoid, both triangle bases are the same length, so we can cut this value in half to get the length of and
Finally, we can use the Pythagorean Theorem to find the length of :
