Hi I have a calculus problem An airplane is flying on a heading of 110o at a constant speed of 525 km/h. If the wind speed vector is 40 km/h at 210 degree, what is the speed vector of the airplane? (Shows diagram of velocity vectors relative to North.)

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
