A vertical post is to be supported by a wooden pole that reaches 3.5 m up the post and makes an angle of 65° with the ground. If wood is sold by the foot, how many feet are needed to make this pole?

You're doing something i dont know how to do but search up on google slope calculator maybe that will get you there

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.
