Answer:
(a) Amplitude = 4
(b) 
--- Period
(c)
--- phase shift
--- vertical shift
Step-by-step explanation:
Given
Rewrite the function as:
Solving (a): The amplitude
A cosine function is represented as:
![f(x) = A\cos[B(x - C)] + D](https://tex.z-dn.net/?f=f%28x%29%20%3D%20A%5Ccos%5BB%28x%20-%20C%29%5D%20%2B%20D)
Where:
So, in this equation (by comparison):
<em>The amplitude is 4</em>
Solving (b): The period (T)
This is calculated as:
By comparison:
So:
Solving (c): The shift
The phase shift is C
The vertical shift is D
By comparison:
--- phase shift
--- vertical shift

Answer:
The second one.
Step-by-step explanation:
The hollow dots represent > or < depending the direction of the arrow. The filled dots represent less than or equal to. So the second.
A. We know the amounts needed for 18 serving, so we can use proportions to scale this up to 108 cups. It is easy once you realize that 4 cups + 8 cups + 12 cups = 18 servings, and 18 * 6= 108, therefore you will need 6 times the amount of ingredients equally proportionated to each of the juices/seltezer. Therefore, we would need 24, 48, 72 cups of pineapple juice, orange juice, and seltzer.
b. Adding 4, 8, and 12 together, we get 24. 108 cups/24 cups of ingredients = 4.5 servings.
c. Using ratios, we see that we use 8 cups of orange juice for every 12 cups of seltzer. Dividing each side by 12, we get that we use 2/3 cups of orange juice for each cup of seltzer.
