Answer:
A)0 sec to 2 sec
B) 2 sec - 3 sec.
C)During 3 to 4 secs water balloon's height decreasing the fastest
D)The height of the water balloon at 16 seconds is 0
Step-by-step explanation:
Given : A linear model with ordered pairs at 0, 60 and 2, 80 and 3, 80 and 4, 20 and 6, 0 and 7, 0 and 8, 0. The x axis is labeled Time in seconds, and the y axis is labeled Height in feet.
x y
0 60
2 80
3 80
4 20
6 0
7 0
8 0
A) During what interval(s) of the domain is the water balloon's height increasing
We can refer the table balloon height increasing from 60 to 80 and then starts decreasing
So, interval = 0 sec to 2 seconds
So, interval(s) of the domain is the water balloon's height increasing is 0 sec to 2 sec
B) During what interval(s) of the domain is the water balloon's height staying the same
We can see that for 2 to 3 secs the height of the balloon is remaining same 80
So, interval(s) of the domain is the water balloon's height staying the same is 2 sec - 3 sec.
C)During what interval(s) of the domain is the water balloon's height decreasing the fastest
During 3 to 4 - Decrease = 60 ft/s
During 4 to 6 - Decrease = = 10 ft/sec
During 3 to 4 secs water balloon's height decreasing the fastest
D: Use the constraints of the real-world situation to predict the height of the water balloon at 16 seconds
After 6 secs balloon has reached ground so it will remain on ground
Hence the height of the water balloon at 16 seconds is 0
