Question 24 • 25-26 CRX Math Models with Applications 7052A
The height, d, in feet of a ball suspended from a spring as a function of time, t, in seconds can be modeled by the equation . The ball is released from its lowest point at seconds. Using your knowledge of the general form of sine and cosine functions, which of the following equations can also model this situation?
Answer
A
d = negative 2 cosine (pi t) + 5
B
d = negative 2 cosine (pi (t + one-half)) + 5
C
d = 2 cosine (pi t) + 5
D
d = 2 cosine (pi (t + one-half)) + 5
