Answer:
The answer is 72 minutes.
Step-by-step explanation:
The first step will be the registration desk, which last 2 minutes.
The second step is going to one of the three cashiers, this step takes 10 minutes.
The third step is to visit one of the four ID processing stations, to take their picture and to print the ID card. this step take 20 minutes.
Demand rate= 0.5 students per minute
This means 1 student every 2 minutes.
The total amount of time of the three-step process is 32 minutes.
During 40 minutes 20 students will start their process. These means that the student number 20 will start his/hers process at the minute number 40 of the whole process. As he/she is the last one, no one will finish their process before him/her.
The process takes 32 minutes.
We just need to add 40 minutes to the total amount of time of the three-step process takes, which is 32 minutes.
Therefore to process 20 students it will take 72 minutes.
we have the function
Remember that
The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2
In the general form of the equation of the sine
The amplitude is the factor A
so
In this problem
The amplitude is 1/2
using a graphing tool
Note that the amplitude is the height from the center line to the peak (the center line is the x-axis, so the distance is 0.5.
