The magnitude of an earthquake is calculated using the Richter Scale, M=log I/io , where I0 is the threshold intensity and the i
ntensity I is given in terms of multiples of that threshold intensity. Which is the correct expression to find the magnitude of an earthquake that had the intensity 980 times the threshold intensity?

Answer:
The length of the diagonal HJ is 10.82 units
Step-by-step explanation:
* Lets revise the rule of the distance between two points
- , where
and
are the two points
* Lets use this rule to find the length of the diagonal HJ
∵ The coordinates of point H are (-4 , 3)
∵ The coordinates of point J are (5 , -3)
∴ and
∴ and
- Lets find the length of the diagonal HJ by using the rule above
∴ HJ =
∴ HJ =
∴ HJ = 10.82
* The length of the diagonal HJ is 10.82 units
