We are given the electricity cost as 5 cents per
kilowatt-hour. We should notice that the cost is actually in the form of:
electrical cost = cost / (power * time)
Therefore to get a number which is in terms of cents
alone (cost alone), therefore we should multiply the given electrical cost
value with the power and time.
Power = 80 watt = 0.08 kilowatt
Time = 24 hours
Therefore the cost is calculated as:
cost = electrical cost * power * time
cost = [5 cents / (kilowatt hour)] (0.08 kilowatt) (24
hour)
cost = 9.6 cents

Step-by-step explanation:
All you need to do is move the decimal.
If you want to know if a function is odd, you look at the exponents/degrees it has; if they're all even it's an even function if they're all odd it's an odd function if it has a mix of both even and odd its neither
the function 9-4x^2 only has one x with an exponent of two making it even
