The orbital period of an object is 2 x 10^7 and its total radius is 4 x 10^4 m.
m/s. (Round to the nearest whole number, do not add any punctuation)
The tangential speed of the satellite is m/s

12,566 not 12560 because edgenuity doesnt want you to round by the tenths only by the ones

Explanation:

Because 2* pi * 4x10^10 = 251327412400 (Dont round the pi to 3.14)

and divide it by 2x10^7

you get 12,566.37 which its 12,566 (and dont add punctuation, stated on the quiz)

  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.
