Technician a says that the reserve rating of a battery is the amount of steady current that a fully charged battery can supply for 20 hours without the voltage falling below 10.5 volts. technician b says that ampere-hour ratings state how many hours the battery is capable of supplying 25 amperes. who is correct1. a only2. b only3. both a and b4. neither a and b.

So here Technician B is correct

Technician B says that ampere-hour ratings state how many hours the battery is capable of supplying 25 amperes.

Explanation:

As we know that ampere hour rating of the battery is the product of current and time

As we know that

here we have

so we can say that ampere hour is the amount of charge that can be flowing through the battery.

So here Technician B is correct

Technician B says that ampere-hour ratings state how many hours the battery is capable of supplying 25 amperes.

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 .
