Applications of Quadratic Functions - Hand In Note: Use Winplot 1. An object is launched at 19.6 meters per second (m/s) from a 58.8-meter tall platform. The equation for the object's height s at time t seconds after launch is: s(t) = -4.9t' + 19.6t + 58.8, where s is in meters. Add numbers to the axis and sketch the graph: Height (m) Time (seconds) Exactly when does the object hit the ground? 2, An agency sells tickets for an opera. Based on previous experience, this agency has determined that the profit they can make on selling x tickets is given by the function P(x) -12x -0.Lc' Add numbers to the axis and sketch the graph: Profit ($) Number of tickets sold What is the maximum profit they can expect to make and how many tickets do they have to sell In order to earn this maximum profit
