Step-by-step explanation:
1 day = 24 hrs
24 hrs = 1440min
1440 min = 103680 b
1 min = x
☓ = 103680 ÷ 1440
x = 72 b
The graph would be similar to a Sin or Cos graph with a vertical shift. As the music gets louder the graph will go up and as the music and crowd become quieter, the graph will go down. Going up and down until the end of the concert where it will be 0.
Also side note, are you by chance in Trig 01 Summer course? If so, I am in the same class haha.
