The depth of a river changes after a heavy rainstorm. Its depth, in feet, is modeled as a function of time, in hours
y is the depth in feet and x is the time in hours
From the table we can see that
In 9 hours, the depth is 18 feet
In 18 hours , the depth is 21 feet
(9,18 ) and (18,21)
Average rate of change = 
= 
= 
= 
the average rate of change for the depth of the river is
feet per hour
Answer: A
Step-by-step explanation:
In order to find constant of proportionality, you have to use the equation, x(?)=y
The ? being the number to plug in, which would be 1/4 in this case. 8 times 1/4 is equal to 2 and so on.
Your answer should be: B. 0.8. Add 1281.6 and 1.6, you get 8.0.
Answer:
