2. Independent and Dependent Variable
x=time y=height
3. Domain and Range
domain: 0 ≤ x ≤ 6.25 range: y ≤ 156.25
4. How long is the golf ball in the air?
The golf ball is in the air for 6.25 seconds.
5. Maximum Height 6. Time at Max
5. (3.125,156.25)
6. The golf ball is at 3.125 seconds at the max.
7. Height of the ball at 3.5 seconds
At 3.5 seconds the height is 154 feet.
7. Yes, There is Another Time
At the height of 154 feet, there is another time of 2.75 seconds.
8. Time of the Ball at 65 feet
The time of the ball at 65 feet is 0.74 seconds because at the y-value of 65 the x-value, 0.74, corresponds.
8. The Other Time of the Ball at 65 feet
The time of the ball at 65 feet is 5.51 seconds because at the y-value of 65 the x-value, 5.51, corresponds.
9. The same height tweety bird and I are at
Tweety bird and I are at the same height at 24 feet.
10. Gloria and Earl
Gloria's golf ball hit the ground first, her golf ball was 1.25 seconds earlier and her golf ball will go 100 feet high.
