With high school would really appreciate!
a chair of weight 90.0 n lies atop a horizontal floor; the floor is not frictionless. you push on the chair with a force of f = 35.0 n directed at an angle of 43.0° below the horizontal and the chair slides along the floor.
using newton's laws, calculate n, the magnitude of the normal force that the floor exerts on the chair.

statement #3 on andre"s list is false.

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 .
