Question 1036276
A rocket is launched from the ground and follows a parabolic path represented by the equation y = -x^2 + 10x. At the same time, a flare is launched from a height of 10 feet and follows a straight path represented by the equation y = -x + 10. 
a. Graph the system and label the points of intersection.
{{{graph(400,400,-2,2,-10,10,-x^2+10x,-x+10)}}}
---------------------------------
b. Describe the points of intersection in context of the problem.
The flare and the rocket at at the same height when x = 0.245
That height is 9.25 ft
