After several successful rocket launches, the Rocket Boys Team is under police investigation. An eye-witness saw a flying object over the water tower near the launch site, linking the witness approximated the height of the flying object to be about 100 feet.
Homer and Quentin worked together to determine the two mathematical models for the flight of their two unrecovered rockets. The models relate height (h) ot the rockets based on the horizontal distance from the launch deck (X) .
Rocket # 1 Model: Rocket #2 Model:
h(x)= -0.0808 (x-35)^2+100 h(x)= -0.4625x^2-3.7x+1
You wre part of the Rocket Boys Team that has been accused of causing a fire in the neighboring forest that is 80 feet away from the launch site. You have been taken to the police station in hand cuffs in front of the whole school. You are now required to give an official statement to the police. In this statement, you will prove to te police that you did not start the fire. Once you prove your innocence, you can continue to reach for your dreams of space exploration like your role model, Dr. Wernher von Braun. To exonerate yourself, your official statement must include the following elements demonstarted with multiple forms of representation, (for example: graphically, algebraicially, and with words)
*Evidence that your rockets could not have traveled far enough to start the fire in the neighboring forest.
*Evidence taht your rockets could not have traveled high enough to be spotted by witnesses.
*Adress possible errors and limitations in your soulution process.
*Adress limitations that the real world imposes on your soulution
Here's the graph of both......... https://www.desmos.com/calculator/km0wtqkfab
The first rocket attained a height of 100 ft but only traveled 70 ft from the launch site...this is the "red" graph
The graph of the second rocket's flight (the blue graph) doesn't make sense....are you sure you have this correct???
I suggest that:
1) you graph each one; this will tell whether or not the rocket was ever high enough (100 + feet) and whether or not if flew far enough (where was the rocket when x = 80?).
2) you replace x with 80 in each equation to see where the rocket was when x = 80. If the value is close to zero, it could have started the fire; if it is not close to zero, it couldn't have started the fire.
@geno3141 I tried graphing it but the graph is on the negative side which is pretty much impossible. I'm really stuck and don't know what to do :(
