Homework Help: math

Posted by jojo on Monday, April 30, 2007 at 9:14am.

The head of an industrial machine moves in a straight line horizontally backwards and forwards from a central position. The movement can be modelled using the sine wave d = 80 sin ( pie t), where d is the horizontal distance (in cm) from the central starting position, and t is the time after the machine starts running (in second).

Choose the one option which gives the distance of the head of the machine (rounded to the nearest cm) from the starting position after 2.4 seconds.
a) 1cm
b) 5 cm
c) 10 cm
d) 75 cm
e) 76 cm
f) 80cm

I have spent a lot of time on this and think it is either B or F. Can anyone help
