Ok, so I've been stuck on this all day and I literally have no idea what to do.
"Use this data to find a function that describes the path of his ball with the height as the dependent variable and horizontal distance as the independent variable. Use this function to answer the follow questions.
Data:
Distance (yds): 0, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Height (yds): 0, 4, 7.5, 14, 20, 24.5, 28, 30.5, 32, 33, 32.5, 31
I tried plugging in the data into the Stat thing or whatever, and then I found the Quadratic regression, and it gave me this equation: y = -.005x^2 + .810x - .006
And these are the questions that came with it:
1. If the green is on the same level as the ball when he hit it and the front of the green is 160 yds. away and the back of the green is 170 yds. away, will the ball land on the green? (Assume he hits the ball straight.)
I get that it's supposed to fall into 160-170, but I don't know how you even arrive at that number. Do you plug something into the function? And is the function is yds.?
2. What is the maximum height of the ball, in feet?
Is this the vertex? And is the function in yards, so I have to convert it?
3. Given the same conditions in #1, will the ball clear a tree that is 35 ft. tall that is 50 yds. in front of the green?
How do I find if it hits something going vertically?
4. Given the same conditions as #1, except that the green is 15 feet above the spot from which he hit the ball, will the ball land on the green?
Please please please help! I've been stuck on this all day!
