Given right triangle ABCABC with altitude \overline{BD} BD
drawn to hypotenuse ACAC. If AC=8AC=8 and BC=4,BC=4, what is the length of \overline{DC}?
DC
? (Note: the figure is not drawn to scale.)

Which expression gives the area of the triangle shown below

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.

The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount during each of the three summer months. the store owner converts the frequency table to a conditional relative frequency table by row. which value should he use for x? round to the nearest hundredth. 0.89 0.90 0.92 0.96
