Question

Use the graph to write an equation
y = acos[b(x – h)] + k to model the situation.

Answer 1

Answer:The amplitude:30

so a:-30

the period is:12

so b: pi/6

Step-by-step explanation:

Answer 2

Answer:

Use the graph to write an equation

y = acos[b(x – h)] + k to model the situation.

The amplitude is  

30

,

so a =  

-30

.

The period is  

12

,

so b =  

✔ pi/6

.

The vertical shift is k =  

50

The phase shift is h =  

-1
