1 rectangle perimeter = 8 +8 +5 +5 = 26
2 rectangle perimeter = 8 +8 +10+10 = 36
3 rectangle perimeter = 8 +8 +15+15 = 46
3rd table is correct
Answer: The amplitude is 4.
Step-by-step explanation:
Given the form of the sine function:

Where
is the amplitude,
is the period and "k" is the vertical shift of the wave.
You know that, in the sine function given (
), you can identify the amplitude and the period. These are:


Therefore, the amplitude of
is:
