A formula for calculating the magnitude of an earthquake is M = zlog that uses to common (base 10) logarithm. This is called the Moment Magnitude Scale (MMS), an alternative
the more well known Richter Scale. One earthquake has magnitude 3.9 on the MMS. If a second earthquake has 800 times as much energy as the first, find the magnitude of the second quake.

You give a $4 tip for a meal that cost $22. approximately what percent of the bill was your tip?

M.xyz =radians. covert this radian measure to its equivalent measure in degrees.

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
