Part C The student's roommate wakes up and turns on in addition to the appliances mentioned in the previous parts the air conditioner (860 W), and he realizes that the room is a mess, so starts to vacuum (630 W). Determine the total rms current in the circuit breaker.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

volts times amps 6 x 0.5 3w

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 .
