The radiation level measured on earth from a certain star is a sinusoidal function of time. at 2: 30 am today, the radiation was at its maximum, 22. the level then decreased to its minimum of 3 at 5: 30 am today. (a) determine the sinusoidal function that gives the radiation level t hours after mid- night last night. (b) starting from midnight last night, how long will it be until the level has been above 16 for a total of exactly 5 hours?

  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.

the inner core.

good luck: )
