using quadratic equation
A firework is launched off a platform 5ft above the ground. The initial velocity of the rocket was 150 feet per second. A function was created to model rocket’s distance from the point it was launched to the point it hit the ground: y= -16x^2+150x+5
All x-values represent time in seconds and all y-values represent the distance traveled by the rocket in feet.
- What is the vertex of your graph? (Round to the nearest ones place)
- What was the maximum height of the rocket? (Round to the nearest ones place)
- Looking at the equation of the rocket’s path, is it factor able?
- Use your graph to estimate how long it took your rocket to hit the ground. (Round to the nearest tenths place)
