Some foresters wanted to predict volume and weight of whole trees in the SE Coastal Plain of the USA. Here is the form of the equation they used and tested:  Log Y= a + b(Log X) + e  Another equation they tested was:  Log Y = a + b(Log X1) + c(Log X2) + e  Question: Explain which equation form would probably predict volume or weight more accurately.

Explain the method you would use to solve these equations: 3x+1=81,3x+1=75. Does your method require logarithms for both equations? Why or why not?

Explain why the values of an increasing exponentialfunction will eventually overtake the valuesof anincreasing linear function.

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.
