Paula found a partially completed table that her friend Donna was using to determine how fast water evaporated from a bucket during the summer. Every other day she measured the height of the water remaining in the bucket in centimeters. 2-94 HW eTool (Desmos). Homework Help ✎
Height cm (
Complete the table.
Looking at the completed days on the chart, by how many cm does the water level reduce every two days?
Use this pattern to fill in the chart.
For this table, what is the rate of change, including the units?
If the water level reduces by
cm every two days, by how many cm does it reduce each day? (It is reducing, so remember that the slope will be negative).
Write an equation to represent the height of the water after any number of days.
Substitute the slope and the water level when
into the equation of a line.
Complete the table in the eTool below and write an equation that represents the data.
