The graph below models the height of a remote-control helicopter over 20 seconds during fl ight. y x 10 5 15 20 (0,46) Time (seconds) H e i g h t ( f t ) (5,19) (15,14) (20,17) (10,20) 50 40 30 20 10 Over which interval does the helicopter have the slowest average rate of change?

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
