Anuclear power plant operates at 68 % of its maximum theoretical (carnot) efficiency between temperatures of 680 ∘c and 400 ∘c. part a if the plant produces electric energy at the rate of 1.5 gw , how much exhaust heat is discharged per hour? express your answer using two significant figures.

13860 Giga Joule/hour

Explanation:

∴ Exhaust heat discharged is 13860 Giga Joule/hour

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
