Why does the graph y= sin(c) continue to go up and down rather than diverge to like the graph of a quadratic, exponential, or any other function.

The equation respenting the left table is

Solve 2x+y=3 x+y=5 in substitution method

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).
