PLZ HELP ASAP 20 POINTS PLZ BY THIS HOUR. Determine the equation of the circle and justify your reasoning,
A. The equation of the circle is (x + y)? = because the curvature of the
circle is formed by a quadratic relationship.
B. The equation of the circle is x + y = r because the radius of the circle is
always equal to the sum of the x and y coordinates.
C. The equation of the circle is x + y = because the Pythagorean
Theorem can be used to describe all points equidistant from the origin
with a radius of r.
D. The equation of the circle is x2 + y = r because the distance formula can
be used to determine all points equidistant from the origin with a radius
of r.

Which graph corresponds to the function f(x) = x2 + 4x – 1?

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.
