The midline is the y value that runs straight through the middle of the wave.If you can picture the standard sine function graph. f(x) = Sin(x) reaches a maximum y = 1 and minimum y = -1 so the midline is y =0.
This equation is shifted up 6 so the midline is shifted up 6
y = 6 is equation for midline
I hope this helps. If you need another explanation just message me
Answer:
the area is 60 square units
Step-by-step explanation:
Area = (base x height) / 2
from class 1 to 2 is 10 units
from class 2 to 3 is 12 units
10 x 12 / 2
10 x 12 = 120
120 / 2 = 60
