Answer:
1) 
2) 
3) 
Step-by-step explanation:
General form of sin function is

Where A is Amplitude
B is 
C is Mid line
1) Given : A sine function has the following key features
Frequency = 
Period is 
Amplitude= 2
Mid line y= 2
Y intercept (0,2)
This function is NOT a reflection of its parent function of the x-axis
Solution : We put the value in the general form of sin function
A= 2 ,
, C=2


2) Given : A sine function has the following key features
Period = 4
Amplitude = 3
Mid line y = -1
Y intercept (0,-1)
Solution : We put the value in the general form of sin function
A= 3 ,
, C=-1


3) Given : A sine function has the following key features
Period = 
Amplitude = 2
Mid line y = -12
Y intercept (0,-2)
Solution : We put the value in the general form of sin function
A= 2 ,
, C=-2


A. y=0.5x+2

Answer:
D. $393.00
Step-by-step explanation:
We have to sum the three distances to get the perimeter.
P= 34 ft + 67 ft+ 30 ft
P = 131 ft
And each foot of material cost $3.00
we get the cost with the distance and de cost of the material:
Cost = 131 ft * 3.00 $ per ft = $393.00
