The profit (in billions of dollars) generated by McDonald's Corp. for the years 2008 to 2015 can be approximated by P(t) = -0.024t^3 + 0.7t^2 - 6.2t + 26, where t = 8 corresponds to the year 2008. Find the rate of change of profit with respect to time.

The net worth, w(t), of a company is growing at a rate of w'(t) = 30000 - 9000t^2 + 400t^3 dollars per year, where t is in years since 2000. a) What is the change in the company's net worth between the years 2000 and 2003? b) What is the worth of the company in 2005 if its worth in the year 2000 is 5 million?

00:01 So here it says the profits in millions of dollars generated by mcdonald's corporation for the years 2008 to 2015.
00:07 It can be approximated by this function right here where eight corresponds to 2008.
00:13 And it wants us to find the rate of change of profit with respect to time.
00:18 So i'm guessing from 8 to 15.
00:20 They want us to find the average rate of change.
00:23 So first i have to plug 8 in for t.
00:41 And i'm going to plug that into my calculator.
00:58 And that gives me negative 106.
01:03 Make sure i put that in there right...
