a particle moves along the x-axis so that its velocity in feet per second at time x, in seconds, is modeled by the quadratic function y = 2x2  − 10x + 12. what does the number 12 represent for the quadratic function?   the particle is 12 feet above the x-axis initially.  the particle's initially velocity is 12.  the particle is 12 feet to the left of the origin initially.  the particle's terminal velocity is 12.

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.
