Bob had a satellite dish installed for his LCD television.  The depth (d) of the satellite dish can be modelled by the relation d = (-0.006w) (w – 60), where (w) represents the width, in centimetres. Find the depth of the dish when the width is 40 cm. The depth of the dish is:

Patricia pays $1.19 each to download songs to her iPod.  If n is the number of downloaded songs, which equation represents the cost C in dollars?

The graph models the path of a basketball after it was thrown from a player’s hands to the basketball hoop, through the net, and down to the floor. The h values represent the height of the ball in feet above the floor and the d values represent the horizontal distance in feet from the player’s hands. How far from the player does the ball hit the floor?  Make an accurate estimate.  Don’t forget the units. The ball hit the floor _________ from the player.
