^^part 3 btw 6th grade math of helping my friend sory I’m out and her thing is due at 2:00 u might need to go to my other questions for some of these

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.
