What is the equivalent resistance in this parallel circuit

The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values. use 1 / R = 1 / R1 + 1 / R2 + 1 / R3 +... A parallel circuit is shown in the diagram above.

Explanation:

Hope it helps and mae=rk the guy on the top branliest cause i got help from him.

The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total: equivalent resistance of resistors in parallel: 1 / R = 1 / R1 + 1 / R2 + 1 / R3 +... A parallel circuit is shown in the diagram above.

Explanation:

mark me as brainliest pls :)

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 .
