Answer:
the answer how you analyzs the problwm
Answer:
1.) dV/dt = -187200πSin(120πt)
2.) No
3.) -187200
Explanation:
The voltage, V, in volts, in an electrical outlet is given as a function of time, t, in seconds, by the function V=156cos(120πt)
dV/dt = -187200πSin(120πt)
Since the rate of change above is negative, that is, its maximum is negative. definitely, it will never be equal to zero.
The maximum value of the rate of change will be its amplitude, which is
-187200
