Chapter 6, Problem 14(choose chapter or problem)
APPLICATION A capacitor is charged with a nine-volt battery. The equation y = 9.4(1 0.043)x models the charge of a capacitor after it is connected to a load. The variable x is in seconds since the capacitor is connected, and y is in volts. a. Is the voltage of the capacitor increasing or decreasing? Explain b. What is the meaning of the numbers 9.4 and 0.043 in the equation? c. Draw a graph of this model for the first minute after disconnecting the battery. d. When is y less than or equal to 4.7 volts? Explain how you found this answer.
