Daily crude oil production by Pemex, Mexico’s national oil company, for 2008-2013 could be approximated by P ( t ) = 0.017 t 2 − 0.4 t + 5.23 million barrels, where t is time in years since the start of 2000. At what rate was oil production changing at the start of 2010? Write a complete sentence and include appropriate units.
Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
