Please answer these questions with explanation! Remember this is college algebra for a 9th grade student so please do not use alpha or beta. Also! please answer #5 which is ta follow up of question #4, I believe I am correct on #4 but I do not know how to do part (d)

PLEASE ANSWER THESE QUESTIONS, I REPOST THEM SINCE SOMEONE ASWER THEM INCORRECTLY, PLEASE I BEG ANSWER ALL THESE QUESTIONS

THEY ARE JUST TWO PLEASE :)

1/5 > OnRamps ERIENCE COLLEGE BEFORE COLLEGE HW 5.4.1 - APPLICATIONS OF THE QUADRATIC FUNCTION Solve the following. 1. "Punkin Chunkin," or Pumpkin Chunking, is the sport of launching pumpkins with cannons and other mechanical devices as far as possible. Teams that compete in these events have names such as American Chunker Inc., Fibonacci Unlimited II, Shooda Noed Beter, and Snot Rocket. The world record was set in 2013, when a pumpkin was launched to a height of 2250 feet and a distance of 4500 feet (measurements have been rounded for simplicity). Assume the motion of the pumpkin was symmetrical. Write a quadratic equation to relate the vertical displacement y, with the horizontal displacement x. How high was the pumpkin when it was 1000 ft away? Units Sold 4. A new tech start-up is trying to sell their app through the various app stores. Looking at similar apps already on the market, they have created a sales demand graph (shown below). The intercepts mean that at $0 they would expect to sell 10,000 coples of their app, but would sell none if they charged 55. a. The units sold follows the equation U = 10000 - 2000P. The money from sales is equal to the units sold times the price P of the unit. Write an equation for sales as a function of price. Demand Curve 10,000P-2,000P^2 b. The upfront costs of creating the app, plus continued maintenance and service, is represented by the equation ( = 2000 - 014 Write an equation Price (5) for costs as a function of price. 3,000-200P The profit from selling the app is equal to sales minus costs Write an equation for profit in relation to price, -2,000P^2+10,200P-3,000 -
