1.
Solve for the indicated value, and graph the situation showing the solution point. The formula for measuring sound intensity in decibels D is defined by the equation D = 10log ( to ) using the common (base 10) logarithm where I is the intensity of the sound in watts per square meter and In = 10-2 is the lowest level of sound that the average person can hear. How many decibels are emitted from a jet plane with a sound intensity of 8.8 . 10- watts per square meter? Round your answer to three decimal places. The jet plane emits Number decibels at 8.8 - 102 watts per square meter.Atmospheric pressure P in pounds per square inch is represented by the formula P = HIE0'21\"": . Twhere a: is the number of miles above sea level. To the nearest foot, how high is the peak of a mountain with an atmospheric pressure of 8.743 pounds per square inch? (Hint: there are 5,280 feet in a mile! The mountain is [ALI-\"oer feet high.

CI" A CD has diameter of 130 millimeters. When playing audio, the angular speed varies to keep the linear speed constant where the disc is being read. When reading along the outer edge of the disc. the angular speed is about 241} RPM (revolutions per minute}. Find the linear speed. Round your answer to two decimal places. The linear speed of reading along the outer edge of the disc is '._--::: meters per second. Consider a right triangle with a side of length a opposite angle A, a side of length y opposite angle B, and a hypotenuse of length z opposite the right angle. If sin B = - 1 V3 and @ = 6, find the length of the other side (y) and the length of the hypotenuse (2). Enter the exact answers. y = Z =Use Figure 1 to evaluate each trigonometric function of angle A. The side adjacent to angle A has length 8 and the side opposite angle A has length 10.
