Aballoon is released 15 feet away from an observer. the balloon is rising vertically at. a rate of 2 ft/sec and at the same time the wind is carrying it horizontally away from the observer at a rate of 3 ft/sec. at what speed is the angle of inclination of the observer’s line of sight changing 5 seconds after the balloon is released?

  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.
