# Hot-Air Balloon Project

## #3 The balloon was at 900 feet, 5 minutes before the balloon was sighted. The graph shows how high the balloon was at 5 minutes before, by calculating the y-values. | ## #2 This table shows the balloons altitude starting from -5 minutes to 10 minutes, and the y-values are the altitude of the balloon at that time. | ## #4 It takes the balloon 39 minutes to reach an altitude of 20 feet. It takes 40 minutes for the balloon to fully land. If you plug in 39 for x in the equation f(x)= 800-20x that equals 780 and thats 20 less than 800. f(x)= 800-20(39) |

## #5 A function that repesents this data is F(x)= 1200-20x It takes 60 minutes for the 2nd balloon to land. This balloon takes 20 minutes longer than the first balloon. They both descend at the same rate, but balloon 2 starts higher in the air, that's why it takes longer. The red line is the 2nd balloon and the blue line is the 1st balloon. | ## #6 A function for this is F(x)= 800-30x It will take about 26.5 minutes for the 3rd balloon to land. It lands about 14 minutes faster than the 1st balloon. This balloon descends faster per minutes. It decreases 30 feet per minutes instead of 20 feet per minute. They both start at the same point (800 feet in the air) but the red line(3rd balloon) lands first because it decreases 30 feet per minute, and the 1st ballon is the blue line. | ## #7 A function for this is F(x)= 30x The first and the fourth balloon will be at the same altitude at 480 feet. The 1st balloon is the blue line, and the 4th balloon is the red line. The intersect shows where both of the balloons are at the same altitude. |

It takes 60 minutes for the 2nd balloon to land. This balloon takes 20 minutes longer than the first balloon. They both descend at the same rate, but balloon 2 starts higher in the air, that's why it takes longer. The red line is the 2nd balloon and the blue line is the 1st balloon.

## #6

It will take about 26.5 minutes for the 3rd balloon to land. It lands about 14 minutes faster than the 1st balloon. This balloon descends faster per minutes. It decreases 30 feet per minutes instead of 20 feet per minute. They both start at the same point (800 feet in the air) but the red line(3rd balloon) lands first because it decreases 30 feet per minute, and the 1st ballon is the blue line.
