The richter scale is used to measure the intensity of an earthquake. if e, measured in joules, is the energy released during an earthquake, then the magnitude is given by where joules. if joules of energy are released during an earthquake, what is the magnitude of the earthquake?

What is the y intercept of f(x)=(1/2)^x?

Hi, can anyone show me how to do this problem? 100 points for this. in advance

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
