Go to a website called desmos it’s a graphing calculator and you just type what you want graphed and it shows it
18 hours = 18/24 reduces to 3/4 of a day
3/4 = 0.75
so 3600/3.75 = 960 watts per day
Uhm, I'm pretty new to expanded form but I think it's something like:
(3 × 1/10) + (1 × 1/100) + (6 × 1/1000)
You can also write it as:
0.3 + 0.01 + 0.006
Let me know if you need working or anything!
