Find the distance between the points.

(9.7, -2.1), (-3.2, 8.1)

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

This is so hard and it’s for a test

Can someone me out here and the tell me the greatest common factor
