Question 1005672: Some figure illustrates the path of a toy racecar that begins at (8,0) and travels d meters counter-clockwise on a circular path with an 8-meter radius. The racecar stops at the point (x,y).
Define a formula that relates the horizontal component, x, (measured in radius lengths as well as meters) in terms of the number of meters, d, the racecar has traveled along the track.
Thanks.

You can put this solution on YOUR website! Some figure illustrates the path of a toy racecar that begins at (8,0) and travels d meters counter-clockwise on a circular path with an 8-meter radius. The racecar stops at the point (x,y).
Define a formula that relates the horizontal component, x, (measured in radius lengths as well as meters) in terms of the number of meters, d, the racecar has traveled along the track.
----------------
The angle A = arc/radius = d/8 (A in radians)
----
x = r*cos(d/8) meters --- (measured in radius lengths)
x = 8cos(d/8) meters --- (measured in meters)
