Answer:  

 

1.     What is the period and the amplitude of the sine function representing the position of the band members as they begin to play?

Answer:  Amplitude is 80 ft, period is 60 ft.

 

2.     Edna is sitting in the stands and is facing Darla. Edna observes that sine curve begins by increasing at the far left of the field. What is the equation of the sine function representing the position of band members as they begin to play?

Answer:  y = 80cos(x*π/30)+80

 

3.     As the band begins to play, band members move away from the edges, and the curve reverses so that the function begins at the far left by decreasing. Darla does not move. The sine curve is now half as tall as it was originally. What is the equation of the sine curve representing the position of the band members after these changes?

Answer: y = 40cos(x*π/30)+80

 

4.     Next, the entire band moves closer to the edge of the football field so that the sine curve is in the lower half of the football field from Edna’s vantage point. What is the equation of the sine curve representing the position of the band members after these changes?

Answer:  y = 40cos(x*π/30)+40

matrenka [14]
You combine like terms which are -10x and 7x and 1 and 37. Then it becomes -3x=36. x would equal to 36/-3, which is -12.

A circle has the equation x^2−8y−6x+y^2=4.
mylen [45]
Hello here is a solution :
x²-8y-6x+y²=4....(1)
A)
x²-6x = x²-2(3)x+9-9
         = x²-2(3)x+3²-9
x²-6x =(x-3)² -9
B)
y²-8y = y²-2(4)y +4²-16
y²-8y = (y-4)²-16
C)
in (1) :

(x-3)² -9 +(y-4)²-16 = 4
(x-3)² +(y-4)² = 29   ...<span>is the standard form of the equation

</span>   <span>Select answer 1 : 
</span><span>A: 3
B: 4
C: (x−3)2+(y−4)2=29</span>
