One freezer costs $623.95 and uses 90 kilowatt hours (kwh) of electricity each month. A second freezer costs $500 and uses 100 k
wh of electricity each month. The expected life of each freezer is 12 years. What is the minimum electric rate in cents per kwh for which the 12-year total cost (purchase price + electricity costs) will be less for the first freezer?

Answer:
The general solution of is
x = 2nπ±
The general solution values
Step-by-step explanation:
Explanation:-
Given equation is
Dividing '2' on both sides, we get
<em>General solution of cos θ = cos ∝ is θ = 2nπ±∝</em>
<em>Now The general solution of </em><em> is </em>
<em> x = 2nπ±</em><em></em>
put n=0
Put n=1
put n=2
And so on
But given 0 < x< 2π
