In a waterfall, water falls 100 ft. Assume all the potential energy change increases its enthalpy (or internal energy, in this case they change by the same amount because this is an incompressible liquid). Assume the specific heat capacity for water is equal to 1.0008 Btu/(lbm·°F). Calculate the temperature rise of the water in °F. (6 points)

answer: a. same unit

explanation:

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 .
