Google Classroom him increased at a constant rate. around him (in atmospheres). 13 2.3 17 2.7 21 3.1 What is the rate of change of the water pressure? atmospheres per meter Show Calculator 9 of 16
Solution
Step 1 ：Select two points from the table: (13, 2.3) and (17, 2.7)
Step 2 ：Calculate the change in pressure: \(\Delta P = 2.7 - 2.3 = 0.4\)
Step 3 ：Calculate the change in depth: \(\Delta D = 17 - 13 = 4\)
Step 4 ：Determine the rate of change of water pressure: \(\frac{\Delta P}{\Delta D} = \frac{0.4}{4} = 0.1\) atmospheres per meter
