Unformatted text preview: MAC 1114 Module Test 4 Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Give the amplitude or period, as requested. 1) Amplitude of y = - 4 sin 5x A) 4 5 B) 4 C) 5 D) 4 Solve the problem. 2) The voltage E in an electrical circuit is modeled by E = 1.5 cos 140 t, where t is time measured in seconds. Find the frequency. (The number of cycles (periods) completed in 1 sec is the frequency of the function.) A) 70 cycles per sec B) 1 140 cycles per sec C) 1 70 cycles per sec D) 140 cycles per sec 3) The graph below represents the amount of fuel consumed by a machine used in manufacturing. The machine is turned on at the beginning of the day, takes a certain amount of time to reach its full power (the point at which it uses the most fuel per hour), runs for a certain number of hours, and is shut off at the end of the work day. The fuel usage per hour of the machine is represented by a periodic function. What is the period in hours of this function?...
