As you have previously seen, the number of minutes S between sunrise and sunset in any one location for a particular day of
the year can be modeled by a variation of the basic sine or
cosine function. One approximate model for the number
of minutes between sunrise and sunset in Washington, D. C.,
is S(d)= 180 sin (0.0172d - 1.376) + 720, where d is the
day of the year with January 1 as day 1.

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
