Use 3.14 for square round to the nearst tenth

The answer is 3.1 BC if u c the four??? The rule I learned is...if it's 5 or up up round up...if it's lower than 5...u don't round @ all & since 4 is less than 5...the 3.1 stays the same...but the 4 is gone bc u used its power & there's ur answer...i hoped this helped ya

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

Not sure what the question is?
