Ms Donn throws a 0.2kg tennis ball to Brandon and a 14kg medicine ball to Jayden. The tennis ball is easier to stop because

The medicine ball has more inertia
The medicine ball is purple
The tennis ball has more mass
The tennis ball is fuzzy and so has more friction

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

this is a good question! i'll do some research and come back when i have the answer!

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 .
