Answer:
Peter gets £13.158 for each kWh of electricity he produces.
Step-by-step explanation:
Peter buys a small wind turbine
Total electricity produced by wind turbine in first year = 13,000 kWh
Total electricity used by Peter = 7570 kWh
Electricity sold to energy suppliers = ?
Total amount of money he gets after selling x electricity to energy suppliers = £412.68
We can se that:
Total electricity produced = Electricity used by Peter + Electricity sold by Peter
Electricity sold by Peter = Total Electricity produced - Electricity used by Peter
Electricity sold by Peter = 13,000 kWh - 7570 kWh = 5430 kWh
Total amount earned = £412.68
So
Price per kWh = Electricity sold by Peter/Total Amount earned
Price per kWh = 5430/412.68
Price per kWh = £13.158

Answer:
Step-by-step explanation:
let me think aha!
From the graph at x = 0, y = 0
Check1:
y = cosx
0 = cos(0)
0 = 1
therefore, this is not the function
Check2:
y = sinx
0 = sin(0)
0 = 0
therefore, this is the function
Conclusion:
the function in the graph is y = sinx
