Over the course of a full year, the daylight in a certain city follows a periodic pattern. The graph below represents the average daylight, in minutes, over the course of twenty-four months, with time t, representing the number of months after January 1 of a certain year. (5.5, 882), (11.5, 563), (17.5, 882), (23.5, 563) What is the amplitude?
To find the amplitude, we need to determine the difference between the maximum and minimum values of the graph.
Looking at the given coordinates, we can see that the maximum average daylight is 882 minutes, and the minimum average daylight is 563 minutes.
Therefore, the amplitude is the difference between these two values:
Amplitude = Maximum - Minimum = 882 - 563 = 319.
So, the amplitude is 319.
