Chapter 3.3, Problem 47E

When there is no wind, a runner is able to run 10 000 m at an average speed of x m/s. When he runs with a tailwind, his average speed increases by 0.05 m/s and it takes him 15 s less to run the 10 000 m. The equation shown below represents this relationship. 10 000 10 000 x+0.05 X = 15, x > 0 6. When there is no wind, find the runner's average speed, to the nearest hundredth of a metre per second.

A pinecone falls from a branch that is 180 feet off the ground. The velocity is given by the /2gh, of a free-falling object where V represents the velocity in feet per second, h is the height in feet, and g is 32 feet per second. What is the velocity of the falling pinecone? equation v =

Plot the point where 0 = 11πT 6
