The Athletic Department at your school hosts a celebrity football game for which no tickets are sold but cash donations are welcome and expected. Since tickets are not collected, they are looking for a creative manner to get a good estimate of the number of fans attending the event. Before the day of the game, you stand in the middle of the field and record the sound intensity level of a friend midway up in the stands as 43.2 dB. Before the game starts, the announcer asks for a big round of applause and appreciation for participating celebrities and you record the sound intensity level as 97 dB. What is your estimate of the number of people attending the event

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
