32. A loop on a roller coaster has its highest point at 42 m and it's lowest point at 18 m. If the height of a cart on the loop of the roller coaster were modelled by a sine or cosine function, what would the amplitude be?
a. 14 m
b. 24 m
c. 21 m
d. 7 m
I thought the answer would be 12cm but it is 7cm, can someone please explain this to me. Thank you!
It also may be possible that the answer on the website is wrong??
