An irrational number is one that can’t be expressed as a simple fraction.
For instance, the first few digits of the square root of two is written as 1.414213562373095... The digits keep going and cannot be expressed as a fraction. But think of 0.33333... That can easily be written as one-third. The distinguishing feature is that there’s no pattern in the digits for the square root of two.
The first two options are integer fractions. We rule those out immediately. The square root of four is tempting, but realize that it is just equal to two. We come to π (pi).
Arguably the most famous irrational number is π, which starts off as 3.14159265358979... Here, there is again no pattern and the digits extend forever. This meets our definition of our irrational.
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept: (9/4,0)
y-intercept: (0,−9)
The bill will be 18,480 if they are successful.
Step-by-step explanation:
Given,
Current bill of company = 22000
Energy usage to decrease = 16%
Amount of decreased usage = 16% of current bill
Amount of decreased usage = 
Amount of decreased usage = 
Amount of decreased usage = 3520
Bill after decreased usage = Current bill - Amount of decreased usage
Bill after decreased usage = 22000 - 3520 = 18480
The bill will be 18,480 if they are successful.
