howard is standing 91 yards from the bottom of a water reservoir. he estimates that the angle of elevation to the top of the water reservoir is about 50°. about how far is howard from the top of the water reservoir?
a.
58 yards
b.
119 yards
c.
142 yards
d.
76 yards

142 yards.

Step-by-step explanation:

See the attached diagram.

Let the reservoir is AC and Howard is standing at B and AB = 91 yards.

Now, the angle of elevation from B to the top of the reservoir C is 50°.

Then using trigonometry,

⇒ ≈ 142 yards.

Therefore, the distance of Howard from the top of the reservoir is 142 yards. (Answer)

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.
