(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
Answer A
They have the same x-intercept but different end behavior as x approaches ∞ :)
All you have to do is multiply the least commen donomenator by 2 and that will be your answer
6/276 = 0.022
Or if you want a simplified fraction, then 1/46
V = x/t = 4.5 mil / 3 h = 1.5 mph
Since, v = 1.5 mph (or we can say that v is constant), distance and time vary directly and the constant of variation is 1.5 mph.
