Answer:
200
Step-by-step explanation:
Mr. Jacob's class reads every day for 20 minutes, which ends up being 20 * 28 because there are 28 days in four weeks. That equals 560
Mrs. Clark's class reads 3 days a week for 4 weeks, so 3*4 = 12. The number of minutes her class reads is 30 minutes so 30*12 = 360.
560-360=200
(3/5 )*2000 would give you 1200, which is your answer
Answer:
Option B. Amplitude =3 midline is y =2.
Step-by-step explanation:
In the graph attached we have to find the amplitude and midline of the periodic function.
Amplitude of the periodic function = (Distance between two extreme points on y asxis)/2
= (5-(-1))/2 = (5+1)/2 =6/2 =3.
Since amplitude of this function is 3 and by definition amplitude of any periodic function is the distance between the midline and the extreme point of wave on one side.
Therefore midline of the wave function is y=2 from which measurement of the amplitude is 3.
