Mrs. Bird set-up her kindergarten classroom so that there was a right triangular area formed by the bookshelves, as shown in the picture below.

If bookshelf A is 6 feet long and bookshelf B is 8 feet long, what is the length of bookshelf C?

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.

1.) 18+5 is one way i’m pretty sure there are others but i can’t think of them right now
