To answer this question let us first define what a rational and irrational number is. A rational number is basically a number whose decimals are terminating (ie have an end) or repeating (continuously repeats the same pattern.
An example of this from your question would be
5.3 - terminating rational number
5.333333333333..... - repeating rational number
Irrational numbers are basically numbers whose decimals are non terminating and non repeating.
An example would be the square root of 29. When plugged in a calculator this would result in <span>5.3851648071.....
</span>This number goes on and on with no set pattern.

Answer:
36.9 m.
Step-by-step explanation:
h(t) = -4.9t^2+25t+6
At time = 3 seconds the height is h3).
h(3) = -4.9*9 + 25*3 + 6
= 36.9 m.
Answer:
10.95'
Step-by-step explanation:
Pythagorean Theorem ()
a = 7' base
b = x unknown side height
c = 13' ladder (hypotenuse)
Using are formula:
49 X = 169
after subtracting 49 from both sides:
= 120
x = 10.95' (round as needed)
