27.5 / 3.5 = 7.86; The average yearly snowfall was 7.86 inches.
The shapes of the 2 graphs are the same. However, because x has a fractional coefficient between 0 and 1, the period of the graphed function is twice as long (that is, 2pi instead of pi), and the graph has been reflected about the x-axis and then stretched vertically by a factor of 3.
If you give the clues I could help.
Step-by-step explanation:
(-13/3) / (-3/4) = 52/9 = 5 + 7/9.
