1) Mary is standing on the road away from the base of a 400 ft tall building. Mary is 5.5 feet tall. Her angle of elevation to the top of the building is 50°. She spots an eagle flying directly above the top of the building. Her angle of elevation to the eagle is 60°. How high above the ground is the eagle?​

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.

Here for a good time of free question aha
