# Quadratic Relation

A golfer hits a tee shot into the rough and the ball stops approximately 120 yds from the green. There is a tree located 40 yds from the ball, directly in the path of the shot. The golfer decides to try to hit the ball over the tree. The path of the shot can be modeled by the equation h = -0.01875x2 + 2.25x, where h is the height of the ball and x is the horizontal distance in yards from where the second shot is taken. (6T/I, 2C)

i) How tall must the tree be to stop the ball?

ii) Does the golfer hit the green with the shot?

iii) What is the maximum height of the ball and when does it occur

h = -0.01875x^2 + 2.25x
in future, use the caret symbol (^) to indicate an exponent

i) This one is simple ... what value should you use for x?

ii) let x = 120 ... what do you get for h? what does that value tell you?

iii) the solution to ii) should help you determine the max height

You understand that ''like" really means "Blast, Skeeter got to it before I did!"
