Question

In some countries, the electricity running to a home oscillates between –240 volts to 240 volts, with a frequency of 90 cycles per second.
Which function represents this scenario?

Answer 1

Answer:

y = 240sin(180πx)

Step-by-step explanation:

This the answer because a is represented by the amplitude, 240, and the frequency is equal to IbI/2pi. to solve for b, multiply the frequency by 2pi.
