My instructor gave us an assignment without discussing the module (mostly demonstrated by complex words rather than figures) to us since she said we should have already tackled this in high school. I was a dropee for three years, so I have trouble catching up. Can anyone explain these problems to me? It's all right even if it's on a single question, and it doesn't have to be the answer. I only want to be clarified since the module is lacking.
I have posted the picture and figures in the attached link down below:
