Answer:
period
Step-by-step explanation:
The attached graph shows a period of the function. Its amplitude is 1/4 (vertical distance from centerline to peak). Its period is 4π (horizontal distance from peak to peak). Its frequency is the reciprocal of the period, so would be 1/(4π).
The value 4π is the period of the function.
He can make 15 chess boards.
All you need to do is multiply 3 by 5.
90°-33°=57°
57=2x+1
-1. -1
56=2x divide both sides by 2
28=x
x =28
14.4 miles
5 goes into 18 3.6 times and 3.6 x 4 = 14.4, she can run 3.6 miles per hour
