A(p + 1) metres long ladder reaches a height
of (2p - 5) metres when it is leaned against a
wall. given that the distance between the foot
of the ladder and the wall is p metres, find the
value of p..

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.
