X = larger number, y = smaller number
x = 5y
x - y = 36
5y - y = 36
4y = 36
y = 36/4
y = 9
x = 5y
x = 5(9)
x = 45
ur numbers are 45 and 9 <==
Here we go ~
In the above question, it is given that :
A.) Find f(2) :
or
B.) Find 
:
so, we can write it as :
Now, put x = , and y = x and we will get our required inverse function ~
C.) Find 
:
The ^3 and ^2 are exponents sorry I don’t think you can type exponents on a keyboard, 6x^3+22x^2+3x-6

Answer:
0.667 ;
0.667 customers ;
0.0166708 hour ;
1.334 customers
Step-by-step explanation:
Given that:
Service time (μ) = 30 seconds ; 2 customers per minute ; 2 * 60 = 120 customers per hour
Arrival time, λ = 80 customers per hour
a.) percentage of time machine is busy (p) ; Utilization factor :
P = λ/ μ = 80 / 120 = 0.667
b.) average number of customers waiting in line Li = p² / 2(1-p)
= 0.667² / 2(1-0.667) = 0.667 customers
c) Average time customer spend in the system = Li/λ + 1/μ
= (0.667 / 80) + (1 / 120)
0.0083375 + 0.0083333
= 0.0166708 hour
= 0.0166708 * 60 = 1.00025 minutes
D) average number in the system ;
Li + p
= 0.667 + 0.667 = 1.334 customers
