Answer:
The second water balloon is in the air longer. Balloon 1 will reach the maximum height faster because it is lower.
Step-by-step explanation:
This is because you drop the first balloon at a height of 105 ft. The second balloon is dropped at a height of 125 ft. The second balloon stays in the air longer because it was dropped at a higher elevation. Balloon 1 will reach the maximum height faster because it is lower.
If this answer is correct, please make me Brainliest!
On my graph, the black line is the equation for Balloon 1 and the red line is the equation for Balloon 2. Since the black line has a lower maximum, this means that Balloon 1 will reach its maximum first.
The standard equation of a circle:
(y-k)² + (x-h)² = R² (1), where R is the radius and h, k are the coordinates of the center.: C(h, k)
In the problem the coordinates of the center C(2,-1).
Replace in (1) h by 2 and k by -1:
(y+1)² + (x-2)² = 25
