(a)
To fill the blank space in the box with the accurate value.
(a)
Answer to Problem 37PPS
The required size is 2.375 yards.
Explanation of Solution
Given information:
Rate of change is the change in
The given table is
Richer Number x | Increase in magnitude y | Rate of change slop |
1 | 1 | |
2 | 10 | 9 |
3 | 100 | |
4 | 1000 | |
5 | 10000 |
Let Richter number is
Now, find the rate of change. Consider the first two row.
Similarly, consider second and third row.
Similarly find all the rate of change for different values of
Hence, the required table is
Richter Number | Increase in magnitude | Rate of change |
1 | 1 | |
2 | 10 | 9 |
3 | 100 | 90 |
4 | 1000 | 900 |
5 | 10000 | 9000 |
(b)
To graph: The points in the Richter vs magnitude plane.
(b)
Explanation of Solution
Given information:
The table for the rate of change is
Richter Number | Increase in magnitude | Rate of change |
1 | 1 | |
2 | 10 | 9 |
3 | 100 | 90 |
4 | 1000 | 900 |
5 | 10000 | 9000 |
Graph:
Consider Richter number as
Interpretation:
Hence, from the graph the
(d)
The exponential equation that represent the Richter scale.

Answer to Problem 37PPS
The required equation is
Explanation of Solution
Given information:
The table for the rate of change is
Richter Number | Increase in magnitude | Rate of change |
1 | 1 | |
2 | 10 | 9 |
3 | 100 | 90 |
4 | 1000 | 900 |
5 | 10000 | 9000 |
Formula Used:
Common ratio for a geometric sequence is
And the nth term is
Here
The given magnitude number are 1, 10, 100, 1000, 10000.
It is observed that the Richter number are in geometric sequence.
Thus, find the common ratio. Use the formula
Let for
Thus, find
