Fireworks California Academy of Mathematics and Science 05/06/11 In the Fireworks unit, a association football squad wants to fire a set of rockets into the air to keep an eye on the schools championship. The rockets go away be fired at the come about of a one hundred sixty foot set at an angle of 65 degrees, and go out be circumscribed so that they rise 92 feet with each second. The soccer squad wants the rockets to actuate once they nominate the maximum identify of their trajectory, and so the team doctor hold ofs to k straightaway how big it provide pip for the rockets to reach their maximum height and reach the farming so that they could company their timing device. Also, for the spectators to get the best panorama of the fireworks, they will postulate to know how high that maximum point is. In arrange to protect the spectators from the fireworks, they will also need to calculate how farther the rockets will land from the towers base so that they could fence off the area. So in summary, the soccer teams demand to grow: 1. How high the rockets will go. 2. How foresightful it will bear before the rockets reach their maximum height. 3. How long it will take before the rockets reach the ground. 4. How far the rockets will travel from the towers base. A friend of the soccer team has reserven them hints on how to find the answers to these questions.

The friend says that the intimacy h(t)=160 + 192t 16t2 will give the answers to psyches 1-3 and that d(t)=92t ÷ tan 650 will give the answer to Question 4. That was all of the hints the friend would g ive, and so now the soccer team has to figur! e out what t represents and how to enlist the manipulation h(t)= 160 + 92t 16t2. There are actually deuce ways to solve the function h(t)=160 + 92t 16t2: using algebra or a graphical recording calculator. To find the answers on a graphing calculator, you insert the function and adjust your window so that you get a graph that looks like a big hill or rollercoaster. You thus trace the acme of the graph (which is basically the middle of the curved graph) to its maximum...If you want to get a full essay, order it on our website: BestEssayCheap.com
