Hot- Air Balloon.
Maya Joseph, Swathi, Ali
Question 1
x-rate of descending
y- altitude
Function:
f(x)= 800-20x
Question 3
The graph is showing the balloon 5 minutes before it was sighted at 900ft.
So it has gone past the positive y axis.
Question 4
The balloon will take the balloon 40 minutes to land.
-You find this by looking on the table you can see when the balloon lands at(40,0)
-If the ballon takes 40 minutes to land and It is decreasing by 20 ft per minute then the ballon takes 39 minutes to reach an altitude of 20 ft since it was first seen.
Question 5
The 2nd balloon
Function:f(x)= 1200-20x
It will take the 2nd ballon 20 minutes longer to land then the 1st balloon.
The descent of the 2 balloons is the same since they both at descending at 20 ft pre minute.
Both of the lines have the same slope, but they have different y-intercepts.
Question 6
The third balloon will land 13 1/3 minutes faster than the 1st balloon and, the third balloons descent is 10ft more, compared to the first balloon.
The relationship between the two lines is how they both ave the same y-intercept which is (0,800)
Question 7
The first and fourth balloon will both have the same altitude at 16 minutes, and the altitude will be 480 ft.
Graphically this is showing the intercept between the to lines.
Question 8
f(x)= 1200-30x
