The table shows world average daily oil consumption from 1985 to 2010 measured in thousands of barrels per day. (a) Compute and interpret the average rate of change from 1990 to 2005. What are the units? (b) Estimate the instantaneous rate of change in 2000 by taking the average of two average rates of change. What are its units?

Step 1
āā¢ Let f(t) denote the world average daily oil consumption in thousands of barrels per day for the year t. āā¢ The independent variable t is measured in years; the function f(t) is measured in thousands of barrels per day. āā¢ Thus, any ārate of changeā we compute Show moreā¦

The table shows world average daily oil consumption from 1985 to 2010 measured in thousands of barrels per day. (a) Compute and interpret the average rate of change from 1990 to $2005 .$ What are the units? (b) Estimate the instantaneous rate of change in 2000 by taking the average of two average rates of change. What are its units? $$\begin{array}{|c|c|} \hline \begin{array}{c} \text { Years } \\ \text { since 1985 } \end{array} & \begin{array}{c} \text { Thousands of barrels } \\ \text { of oil per day } \end{array} \\ \hline 0 & 60,083 \\ 5 & 66,533 \\ 10 & 70,099 \\ 15 & 76,784 \\ 20 & 84,077 \\ 25 & 87,302 \\ \hline \end{array}$$
Derivatives
The table shows world average daily oil consumption from 1985 to 2010 measured in thousands of barrels per day. (a) Make a scatter plot and decide whether a linear model is appropriate. (b) Find and graph the regression line. (c) Use the linear model to estimate the oil consumption in 2002 and 2012.
