the track of a roller coaster passes over several hills and then goes into a tunnel. Near the tunnel,it follows the path
h= 1/72 (d-12)(d+12),
where h metres is its height above the ground and d metres is a measure of horizontal distance.
a)find the horizontal distance between the entrance and exit of the tunnel.
b) How deep is the tunnel ? Justify your answer. the track of a roller coaster passes over several hills and then goes into a tunnel. Near the tunnel,it follows the path
