Please Help with Questions

1) You noticed a large water tower near the Towers of Trig. You get the idea that if its tall enough the park could put some advertisement on it. Thankfully, you brough the following items with you:
▪ Paper ▪ Pencil ▪ Eraser ▪ Calculator ▪ Measuring tape
a) Explain how you can use the above tools and similar triangles to calculate the height of the tower.
b) You remember that your phone has an app that measures angles of elevation and depression. Explain how with the addition of this you could use right angled trigonometry to determine the height of the tower?
2) The park had initially planned to charge $8 admission and was expecting 2400 visitors each day.
a) How much revenue will the park have for one day based on the pricing described above? Show your work.
b) The marketing department did some research and determined that for every $0.50 increase in price the park will lose 60 visitors. Determine the parks revenue if the price were increased by $1. Show your work.
c) After a few calculations, the class determines that the park will make more money if they raise the admission price. But they also know that if the price is too high, they will lose too many people and will end up with less revenue. As a result, the class determined the relation, ? = (2400 − 60?)(8 + 0.50?), represents the revenue, ?, depending on the number of price increases, ?. i. Write the revenue expression in standard from. ii. Use this to determine at what ticket price(s) the company will make $16770 in revenue. iii. Write the revenue expression in vertex form. What is the maximum revenue? At what ticket price will the park make this maximum revenue?

Hi. This is a math help site where we help students solve their problems. We do not solve problems for students. So please show us the work you have done and we can help you to arrive at the correct answers. Thanks

The problems you posted are clearly part of a larger project, which reminds me of a project assigned in one course in my school, which tutors are explicitly told not to help with, and students are explicitly told to do on their own, because they have had plenty of homework in which to learn the techniques they need. (We can help them with that homework.)

So I need to ask: Will your teacher have anything to say if they find this question posted here?

No, this is not a marked assignment. Just practice questions for my exam. I do not know how to upload photos of stuff I have done, so was hoping to have some help with the general steps solving these questions

Please discuss:

a) Explain how you can use the above tools and similar triangles to calculate the height of the tower .

Please pick a problem and tell us what ideas you have. Some of this calls for creativity, or perhaps for remembering specific examples you've been given. In particular, I really don't know what specific method they might have in mind for (1a); anything I think of would require a little more. Perhaps you could use the length of the pencil as one side of a triangle? But (1b) is a little more obvious.

Problem 2 is quite different, and really should have been submitted separately.

In any case, we really need your input to know what help you need.
