3. Use the diagram below. Let there be a dilation from center 0. Then, Dilation(P) = p. In the diagram below,
TOP] = 18 cm and OP'] = 9 cm. What is the scale factor r? Show your work.
9 cm
o
18 cm

#12 find the value of x. #13 find the value of the variable.

1foot = 12 inches; 1 yard = 3 feet

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.
