1) Calculate the magnetic force on a 210 m length of aluminum wire stretched between two towers along an Interstate Highway. The wire is
carrying 230 amps of current. The earth's magnetic field of 5.4 x 10-5 Tesla
at the given location and the field lines are perpendicular to the wire. *
0.65 N
2.3 N.
1.3 N
O 2.6 N

ill do it for 100, also this isnt 80 its 40

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 .
