The P-WAVE of an earthquake TOOK 7 MINS TO TRAVEL to a seismic station from the epicenter of the earthquake. What is the seismic station's distance to the epicenter of the earthquake AND How long did it take for the first S-wave to travel that distance?

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.
