K Prove graphically and algebraically that a clockwise rotation of 270° about the origin has an equivalent
counterclockwise rotation. In your final answer, name the equivalent counterclockwise rotation and show all of your
work. On your graph, label the following:
1 parallelogram PARK and the coordinates of all four of its vertices
2 parallelogram P'A'R' K' and the coordinates of all four of its vertices
3. center of rotation and its coordinate
4. the Invisible circle of rotation, its radius and the length of the radius
5. use arrows to show the clockwise movement of the parallelogram

In new york city at the spring equinox there are 12 hours 8 minutes of daylight. the longest and shortest days of the year very by two hours and 53 minutes from the equinox in this year the equinox falls on march 21 in this task you use trigonometric function to model the hours of daylight hours on certain days of the year in new york city a.what is the independent and dependent variables? b.find the amplitude and the period of the function. c.create a trigonometric function that describes the hours of sunlight for each day of the year. d. graph the function you build in part c. e. use the function you build in part c to find out how many fewer daylight hours february 10 will have than march 21. you may look at the calendar.
