Use the triangles below to find the missing length of the segment tu.

If you don't include all the information, i can't you. however, if the question is what i think it is (and the rectangle is being split into two triangles) you can use the pythagorean theorem to solve the question.

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.
