(a)
To graph : The given situation using
Given information :
The Modified Mercalli Intensity Scale rates an earthquake's "shaking strength". In general, the rating decreases as distance from the earthquake's epicenter increases. Suppose an earthquake has a Mercalli rating of
Graph :
The graph representing the given situation will be as below:
Interpretation :
The distance from the epicenter will be the radius of the circles.
(b)
To explain : An inequality for each circle describing the coordinates of locations with Mercalli rating at least as great as the Mercalli rating represented by the circle.
The three required equations are
Given information :
The Modified Mercalli Intensity Scale rates an earthquake's "shaking strength". In general, the rating decreases as distance from the earthquake's epicenter increases. Suppose an earthquake has a Mercalli rating of
Explanation :
For the first earthquake having Mercalli rating
For the second earthquake having Mercalli rating
For the third earthquake having Mercalli rating
Therefore, the three required equations are
(c)
To calculate : The Mercalli rating
The prediction can be made using
Given information :
The Modified Mercalli Intensity Scale rates an earthquake's "shaking strength". In general, the rating decreases as distance from the earthquake's epicenter increases. Suppose an earthquake has a Mercalli rating of
Explanation :
The value of Mercalli rating
Therefore, the prediction can be made using
