What is the scale factor if a1 is 15 and a2 is 60?

If area 1 is 15, and area 2 is 60, we need to divide the larger area by the smaller area. This gives us our scale factor.

60 / 15 = 4.

Your scale factor is 4, meaning for every 1 of area1 is 4 for every area2.

I hope this helps!

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.
