So, Either:

=> -s = 0   OR    s-2 = 0

=> s = 0     OR     s = 2

s=0,2

Step-by-step explanation:

-s^2+2s=0

Factor out -s

-s ( s-2) =0

Using the zero product property

-s =0  s-2 =0

s=0   s=2

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.

its less than 713.21 but greater than 5.2
