"In the second task, you will have to determine the parts of the atom. This should include creating a data table in a word program. The data table will need to include the mass and charge of an electron, proton, and neutron. You will also need to explain what subatomic particles are represented by the atomic number and mass number on the periodic table. In addition, you will need to explain what the nucleus and electron orbitals are. You will need to determine which makes up the volume of the atom, and which makes up the majority of the mass. You will need to sketch a model of an atom with at least 5 protons to represent these ideas."

these are the directions. but i dont understand them

I have to write a report for school, and my teacher gave me a rubric for it. (A rubric is basically a paper with boxes on it you write information down on)

It has a place for the "Topic Statement" And then
A place you to write "evidence cited" things.

In your opinion, does this mean only write citations or can it be non-cited information also?

Here is the second one. All I need to know are the variables that need to be assigned and the linear equations that need to be used. I also need the function. I can solve maximum and minimum by myself:
Juan makes two types of wood clocks to sell at local stores. it takes him 2 hours to assemble a pine clock, which requires 1 ounce of varnish. It also takes 2 hours to assemble an oak clock, which takes 4 ounces of varnish. Juan has 16 ounces of varnish in stock, and he can work 20 hours. If he makes $3 profit on each pine clock and $4 on each oak clock, how many of each type should he make to maximize his profit?
