Problem 2. A river is 15m wide. Soundings of the depth are made at equal intervals of 3 m across the river and are as shown below. Depth (m) 0 2.2 3.3 4.5 4.2 2.4 0 Calculate the cross-sectional area of the flow of water at this point using Simpson's rule.​

rounding to the nearest thousandth would be 452,000

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
