I have to do this project for my virtual course and I'm stuck on this part.

First off, the equation is y = -16x2 + 341.73 + 0

7. Use the graphing technology of your choice to graph the above equation and determine the x-intercept values. Set rounding to 5 places. Save a copy of this graph and paste or attach it to this Worksheet. (5 points)
8. What are the x-intercept values? (5 points) 8.791, 9.791, 10.971, 11.791, 12.791?
9. How long does this mean the water from your fountain will remain in the air? (3 points)

I don't get how to get number nine, and I also don't think I did number 8 wrong.

its basically asking you for the distance, (time), between the the 2 x intercepts :)

That doesn't really help me.

alexwee123 · Answer

like say that the intercepts are (0,0) and (4,0)
|dw:1341712559697:dw| 
from 0 to 4 the water would be in the air because (0,0) is where the water leaves and (4,0) is where the water lands
