BQ 7: Unit V

The difference quotient, which is shown in the link below, comes from the slope of the secant line through two points on the graph of f. These are the points with x-coordinates x and x + h. The difference quotient is used in the definition the derivative. The difference quotient allows you to find the slope of any curve or line at any single point. The difference quotient is the change in "y" divided by the change in "x." The only difference is that in the slope formula, y is used as the y-axis, but in the difference quotient, the change in the y-axis is described by f(x).

WPP#13-14: Unit P concept 6-7: Applications with Law of Sines and Cosines

1.) Ricky and Ana went a a family bbq to watch the game.  However, no one could find the remote to turn on the tv so they quickly all tried to look for it before the game started. Ana looked under the couch when it was north of the couch and at Ricky was looking in the cabinets which was 25 yards away from Ana found it. Ricky saw the remote  N28E from a north-south line through where was standing and Ana saw the ball's path  N39W from a north-south line through where she is standing. What is the distance between Amarie and the football?

2) Ricky and Ana were playing baseball and they both ran to catch the ball. Ricky ran 12 yards at a bearing on 56 degrees and Ana ran 14 yards at a bearing of 315 degrees. how far apart were they before starting to run?
