Rational number:
Rational numbers are the numbers that can be expressed in the form of a ratio (PQandQ0)
and also if decimal number represents the number after the decimal is repeating, then it is a rational number.
Irrational numbers:
It is impossible to express irrational numbers as fractions or in a ratio of two integers, irrational numbers have endless non-repeating digits after the decimal point.
34 It is a rational number.
9=3 It is a rational number.
33=3 It can not be simplified more, so, it is a irrational number.
255=5 It can not be simplified more, so, it is a irrational number.
20=201 it is a rational number.
1.11222 it is a rational number because 2 is repeating here.
5.5015132 it is non-recurring and non-terminating. So, it is a irrational number.
626262 it is a rational number.

Exponential Growth and Decay
Exponential growth and decay problems follow the model given by the equation A(t)=Pert
-The model is a function of time t
-A(t) is the amount we have ater time t
-PIs the initial amount, because for t=0, notice how A(0)=Pe0×t=Pe0=P
-Tis the growth or decay rate. It is positive for growth and negative for decay
Growth and decay problems can deal with money (interest compounded continuously), bacteria growth, radioactive decay. population growth etc.
So A(t) can represent any of these depending on the problem.
Practice
The growth of a certain bactenia population can be modeled by the function
A(t)=900e0.0534
where A(t) is the number of bacteria and t represents the time in minutes.
What is the initial number of bacteria? (round to the nearest whole number of bacteria.)

How does the DISCRIMINANT really work?
I have the following equation (depended on param a)
(a22a)x2+2ax1=0
I want to find out what the behavior of this equation after changing the value (by behavior I mean finding out how will the root count change when I put x or y instead of a). So for that purpose I thought it might be useful to find the D. If i'm not wrong when we have b=2k, then we can simply use this formula:
D=k2ac=a2+(a22a)=2a22a=2a(a1)
so after having this done, I thought maybe I can find out where my equation has only 1 root:
2a(a1)=0,a=0,1
but after putting for example a=0, I quickly noticed that there my equation has no roots(real roots I think).
a=0,1=0x
Can someone explain me what I've missed here? Shouldn't a=0, work just fine (I mean give me only 1 root)?
