a.
To calculate: The value of n to evaluate the electrical consumption in a city.
a.
Answer to Problem 25OE
The value of n to evaluate the electrical consumption in a cityis
Explanation of Solution
Given information:
In a city the annual electric consumption is formulated as
Consider the provided statement in a city the annual electric consumption is formulated as
To evaluate the annual electric consumption at the present that is now so, the value of n should be 0 as it is the initial time.
Thus, the value of n to evaluate the electrical consumption in a city is
b.
To calculate: The value of n to evaluate the electrical consumption in a city 10 years from now.
b.
Answer to Problem 25OE
The value of n to evaluate the electrical consumption in a city 10 years from now is
Explanation of Solution
Given information:
In a city the annual electric consumption is formulated as
Consider the provided statement in a city the annual electric consumption is formulated as
To evaluate the annual electric consumption at the present that is now so, the value of n should be 0 as it is the initial time.
Next, to evaluate the annual electric consumption 10 years from now so, the value of n should be 10 as it deals to 10 years ahead of present time.
Thus, the value of n to evaluate the electrical consumption in a city 10 years from now is
c.
To calculate: The value of n to evaluate the electrical consumption in a city 10 years ago.
c.
Answer to Problem 25OE
The value of n to evaluate the electrical consumption in a city 10 years agois
Explanation of Solution
Given information:
In a city the annual electric consumption is formulated as
Consider the provided statement in a city the annual electric consumption is formulated as
To evaluate the annual electric consumption at the present that is now so, the value of n should be 0 as it is the initial time.
Next, to evaluate the annual electric consumption 10 years ago so, the value of n should be
Thus, the value of n to evaluate the electrical consumption in a city 10 years agois
