I need help guys this time it is 6 points cuz I'm poor so PLZ help I really need it

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.

Which value would be a solution for x in the inequality 47-4x< 7

How can you find the magnitude of a vector, v = < x,y > , where the horizontal change is x and the vertical change is y?
