The magnitude of an earthquake, R, can be measured by the equation r=log(a/t)+d, where A is the amplitude in micrometers, T is measured in seconds, and D accounts for the weakening of the earthquake due to the distance from the epicenter. If an earthquake occurred for 4 seconds and D = 2, which graph would model the correct amount on the Richter scale?

Functions can be represented using equations and graphs

The function that represents the magnitude of an earthquake, R, is [tex]r = \log(0.25a) + 2[/tex]

How to determine the graph of the function

The equation of the function is given as:

[tex]r = \log(a/t) + d[/tex]

From the question, we have the following parameters

t = 4 seconds

D =2

So, the function becomes

[tex]r = \log(a/4) + 2[/tex]

Divide a by 4

[tex]r = \log(0.25a) + 2[/tex]

Next, we plot the graph of the function (see attachment)
