Answer:
m= 20 because the rate of change is -3.
Answer:
-32°F
Step-by-step explanation:
8°F - 40°F
=> 32°F
* -21x + 9y = 66
21x + 28y = 28
37y= 94
y= 94/37
* -3x - 4y = -4
-3x - 4(94/37)= -4
-3x = -4 + (4*(94/37))
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
