Write the equation of the circle that has a center at point K (2, 4) and passes through the point (6, 5).

The triangles are similar. what is the value of x? show your work.

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.

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?
