Step-by-step explanation:
1. Ampltiude is 1
The period is

is the period
The phase shift is 0
2. The Ampltiude is 2
The period is 2 pi
The phase shift is 1
3. The amplitude is 3
The period is 2 pi/3
The phase shift is -2
4.The amplitude is 2/3
The period is -10pi
The phase shift is 0
5. The Ampltiude is 1
The period is -2 pi
The phase shift is pi
6. The amplitude is 1/4
The period is -4pi
The phase shift is negative 2pi/3
7. The Ampltiude is 3
The period is 4
The phase shift is 8
just count how many there and and eliminate one by one
Start by combining like terms:


Now we have:

Divide both sides by 2 to isolate s

Final answer:
s=12
79. Is 52 800 centimeters greater than 1 kilometer?
According to the unit of conversion in every 1 kilometer, there is a total of 100 000 centimeters.
Now, the given value of centimeters is equals to 52 800
=> 1 km = 100 000 cm
=> 52 800 cm is less than the value of 100 000 cm which is equivalent to 1 km.
Thus, the given is not correct. 52 800 cm is less than 1 kilometer.
Answer:
The second answer.
Step-by-step explanation:
An x squared term cannot be combined with a term with just an x.
