Help quick Question 1
An eagle is flying from point A to B in order to catch a sparrow. Its flight path is a parabola that can be modeled by an equation y= -5(x-6)^2+30, where x is the horizontal and y is the height of the eagle in meters.

If the eagle starts and ends at a height of 20 meters, how far away are points from one another? Round to the nearest whole number.
