Answer:
Step-by-step explanation:
Amplitude is twice the coefficent of the sine function. In this case,
Period is divided by the coefficent of x, in this case,
Phase shift, is how much you sum or subctract from x inside the sine, in this case .
Midline you get by hiding the sine and reading what's left, in this case, -4.

Answer:
C
Step-by-step explanation:
The central angle is equal to the arc that subtends it, that is 54°
area of sector = area of circle × fraction of circle
A = πr² ×
= π × 10² ×
= 100π × ( cancel 20 and 100 )
= 5π × 3
= 15π cm² → C
