Question 9 of 12 • Common Core Algebra II - MA3111 B-CR
The height, h, in feet of the tip of the hour hand of a wall clock varies from 9 feet to 10 feet. Which of the following equations can be used to model the height as a function of time, t, in hours? Assume that the time at t = 0 is 12:00 a.m.
Answer
A
h = 0.5 cosine (StartFraction pi Over 12 EndFraction t) + 9.5
B
h = 0.5 cosine (StartFraction pi Over 6 EndFraction t) + 9.5
C
h = cosine (StartFraction pi Over 12 EndFraction t) + 9
D
h = cosine (StartFraction pi Over 6 EndFraction t) + 9
