What is the similarity ratio of the smaller to the larger similar pyramids? enter your answer as a: b.

The 'similarity ratio' is their fancy name for the ratio of
corresponding sides of two drawings that are 'similar'.

In these similar pyramids . . .

-- the 9 of the small one corresponds to the 12 of the big one.
Their ratio is  9/12 = 3:4 .

-- the 18 of the small one corresponds to the 24 of the big one.
Their ratio is  18/24 = 3:4 .

Notice that they're the same ratio.  If they WEREN't the same ratio,
then these two pyramids wouldn't be similar, even if somebody said
that they are. 

The similarity ratio for these two figures is  3:4 .

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.
