Consider this equation.

|y + 6| = 2

In the 30-60-90 triangle below side s has a length of and side r has a length

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.

State one method by which you can recognize a perfect square trinomial.
