Minimal norm least square solution. applying previous problem to the equation ax = pranab show that a) there exists a unique least square solution x0 of ax = b minimizing the norm kxk. b) x0 = p (kera)? x for any least square solution x of ax = b.

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.
