5. You're holding a sound sensor in your hand as you leave the library. The sensor display reads
40 dB inside the library. After you walk out the front door, the sound of traffic on the busy street
causes the sensor to read 80 dB. How many times louder is it outside the library compared with
inside? (8 points)

explanation:

1 the 4 is sig

  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.
