construct a table that includes
-a comparison of the nature of the two solutes
-a possible example of each solute
-an explanation of the ability of each solute to conduct electricity when placed in water
(on beaker B the circle is white, not black , my mistake)

During a soccer match, Tony, at point A, passes the ball to Eoin, at point C, to avoid the defender at point B. Eoin then kicks the ball towards the 7.32 m wide net in an attempt to score. The path of the ball is modeled by the absolute value function . Suppose a Cartesian plane is superimposed over the opponent’s half of the pitch such that the opposite corners of the field of play have the coordinates (0, 60) and (90, 0), as shown.
a.At what point does Eoin receive the ball?
b. If player B does not intercept the ball, verify whether or not the ball makes it into the goal.
c.If Tony passes the ball from point (5,36), state the domain and range of the absolute value function, within the context of this situation.
