An iPad requires an average of .21 A of current from a 120-V outlet for 1.5 hours to completely charge. How much energy is used? If Consumer's Energy charges $.13 per kilowatt hour what would be the charge if you had to charge 10 iPads?

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
