The alarm in a noisy factory is siren whose volume, V decibels, fluctuates so that E secone after starting, the volume is given by the following function V() = 18sin + 60 %3D a. Sketch the function, including appropriate window settings. b. What are the maximum and minimum volumes of the siren? C. Determine the period of the function. d. After how many seconds, to the nearest tenth, does the volume first reach 70 decibels? e. How many seconds does it take for the alarm to reach 55 decibels for the first time? f. The background noise level in the factory is 45 decibels. Between which times, to the nearest tenth of a second, in the first cycle is the alarm siren at a lower level than the background noise?
