Question: Fireworks Applications Name: Unit 9: Date: You decide to change the bursting altitude of the fourth rocket so that the bursting altitude is at least

Fireworks Applications Name: Unit 9: Date: You decide to change the bursting altitude of the fourth rocket so that the bursting altitude is at least 580 feet. 1) Write a quadratic inequality to indicate that the bursting altitude must be greater than or equal to 580 feet. Write an inequality to show this. 2) Give a range (or interval) of fuse times for this rocket. Explain how you used your graph to answer this question. Now you must plan the launching and bursting of the next three fireworks in the show. Their initial upward velocities are given in the table below. (HINT: Make 3 different inequalities and solve.) Rocket The Screamer Mod Quad Newton's Glory Velocity (feet per second) 160 200 240 Bursting altitude at least 350 feet above at least 350 feet above at least 350 feet above the ground the ground the ground Maximum height Time to reach max height Fuse time interval
