a model rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y=0.06x^2+10.1x+5, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above ground?

a) 168.83 m
b) 5.00 m
c) 84.17 m
d) 168.34 m

You're given the problem itself. However you don't know what you're looking for... I don't know how you got that answer if they didn't state what you're looking for.

sorry i left a part out

anonymous · Answer

the question is: How far horizontally from its starting point will the rocket land?

the_fizicx99 · Answer

Basically find the soultions

anonymous · Answer

could you help me out with this one i have another like it and if you help me on this one I'll do the other one on my own, this stuff really confuses me

anonymous · Answer

btw...I think it's A but not really sure

the_fizicx99 · Answer

Use the quadratic formula, or graph it. Graphing it is allot faster. Just find when it touches the x axis. There should be 2 solution's, use the one that's positive.

ok hold on

I think I got the answer.................C

anonymous · Answer

?!?!?!?!

anonymous · Answer

Can I get a confirmation on whether that's right or not?

the_fizicx99 · Answer

There's something wrong... are you sure that the equation isn't y = -0.06x^2+10.1x+5

anonymous · Answer

yes I'm sure the question says y=0.06x^2+10.1x+5

the_fizicx99 · Answer

If I'm right, no, it's not C.

the_fizicx99 · Answer

Can you print screen the whole problem?

anonymous · Answer

umm, I'll try

anonymous · Answer

ok I can't

K, have fun. Pretty sure there's something wrong with the problem if it isn't negative. Hm!
 It says what's the distance between the starting point and where it landed. I actually got D when I subtract 168.8 -0.5. This being the equation says -0.06x^2
