The population of a small country is 5,740,000. express this number using scientific notation

So scientific notation is making the number manageable.

scientific notation is
(a number >1 and <10) times 10^x

we count how many places the decimal has to move to make the number >1 and >10.

the answer is 6.
5.74 times 10^6

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.
