Answer to Question 3
 "y" is measured in feet. |

a) The highest point will be the vertex (maximum) of the graph.
Algebracially find the axis of symmetry (-b/(2a)) which is x = 0. The y-value will be 4, so the highest point is (0,4). The highest point is 4 feet above the water level.
b) The horizontal distance will be the distance between the two roots of the equation (x = ±5) for a distance of 10 feet.
c) 6 inches is ½ a foot.

The distance between the spout height of 6 inches on the arc will be 9.354143467 feet, or approximately 9.4 feet. |
