The loudness of a sound is measured in decibels. Like measurement of earthquakes, the decibel level is calculated using logarithms and the lowest sound intensity, 10-12 watts per square meter, that a human ear can detect. The loudness of a sound in decibels can be found using the function L(1) = 10 log 10-12 when the sound has the intensity of I watts per square meter. The sound of fireworks has an intensity of 100 watts per square meter. What is the decibel level of a fireworks show? dB

The intensitylevels I of two earthquakes measured ona seismograph can be compared by the formula logI1I2=M1M2 where M is the magnitude given by the Richter Scale. In August 2009, an earthquake of magnitude 6.1 hitHonshu, Japan. In March 2011, that same regionexperienced yet another, more devastating earthquake, this time with a magnitude of 9.0.[23] Haw many timesgreater was the intensity of the 2011 earthquake?Round to the nearest whole number.
