Antoine pulls a weight attached to a spring below its resting, or equilibrium, position. When Antoine releases the weight, it oscillates above and below its equilibrium position as shown in the table. The displacement of the weight from its equilibrium position, d(t), in centimeters, is modeled by a cosine function, where t represents time, in seconds. t 0 0.015625 0.03125 0.046875 0.0625 0.078125 0.09375
d(t) -20 -14.14 0 14.14 20 14.14 0

At which interval is the weight above its resting position? HINT: It's not C.

A. (0, 0.03125)
B. (0.03125, 0.09375)
C. (0.046875, 0.078125)
D. (0.03125, 0.0625)
