1. the richter scale is used to measure the magnitude of an earthquake. the magnitude, r, is given by the equation: r=0.65log(0.39)e +1.45, where e is the energy (measured in kilowatt-hours) released by the earthquake. determine the amount of energy released by an earthquake of magnitude 7.5.
2. use synthetic division to find the quotient and the remainder.
(12x^4+5x^3+3x^2-5) ÷ (x+1)
