I'd seriously appreciate it if anyone could ! : ) i'll give brainliest! show your work. the depth of a river changes after a heavy rainstorm. its depth, in feet, is modeled as a function of time, in hours. consider this graph of the function. write the average rate of change for the depth of the river, measured as feet per hour, between hour 9 and hour 18. round your answer to the nearest tenth.

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

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

they would have to work 32 hours.
