What function relating the varibles best describes this situation?
The equation is saying that it starts at 800 and because it is decreasing, you subtract 20 times "x".
Make graph to show the balloon's altitude every 5 minutes beginning at 5 minutes before the balloon was sighted until the balloon lands.
How high was the balloon 5 minutes before it was sighted? Explain.
A second balloon is first sighted at an altitude of 1200 feet but is descending at 20 feet per minute. Write the function that represents this situation. How much longer does it take for the second balloon to land compared with that of the first balloon? How does the descent of the balloons compare? Show the graph. Explain the relationship between the two lines.
It takes a little bit longer because it starts higher and is going at the same pace. They end up crossing at 400 feet altitude.
At the instant the first balloon is sighted, a fourth balloon is launched from the ground rising at a rate of 30 feet per minute. Write the function that represents this situation. When will the first and fourth balloon be at the same altitude? What is that altitude? Show the graph. What does this mean graphically?
You have plus 30x because the balloon is going up not down. they cross at 800 feet altitude.
