- A builder wants to build the bridge whose cross section is shown in the diagram. Complete problems 1–2. 1. An equation to find the distance b, in feet, between each beam is 99. (Simplify your answer.)arrow_forwardThe speed of a supersonic aircraft is usually represented by a Mach number, named after Austrian physicist Ernst Mach (1838–1916). A Mach number is the speed of the aircraft, in miles per hour, divided by the speed of sound, approximately 740 miles per hour. Thus, a plane flying at twice the speed of sound has a speed, M, of Mach 2. If an aircraft has a speed greater than Mach 1, a sonic boom is heard, created by sound waves that form a cone with a vertex angle θ,, shown in the given figure. The relationship between the cone’s vertex angle, θ,, and the Mach speed, M, of an aircraft that is flying faster than the speed of sound is given by sin θ/2 = 1/M. Solve, If θ = π/6, determine the Mach speed, M, of the aircraft. Express the speed as an exact value and as a decimal to the nearest tenth..arrow_forwardFor Exercises 33–38, find the exact value of each expression without the use of a calculator.

A company's profit varies directly as the number of products it sells. The company makes a profit of $1175 on the sale of 25 products. What is the company's profit when it sells 105 products? 69. The distance that a body falls from rest varies directly as the square of the time of the fall. If skydivers fall 144 feet in 3 seconds, how far will they fall in 10 seconds? 70. The pitch of a musical tone varies inversely as its wavelength. A tone has a pitch of 660 vibrations per second and a wavelength of 1.6 feet. What is the pitch of a tone that has a wavelength of 2.4 feet? 71. The loudness of a stereo speaker, measured in decibels, varies inversely as the square of your distance from the speaker. When you are 8 feet from the speaker, the loudness is 28 decibels. What is the loudness when you are 4 feet from the speaker? 72.
