Two students, ann and max, factored the trinomial 4x2 − 6x − 4. •ann factored it as 2(x − 2)(2x + 1). •max factored it as (x − 2)(4x + 2). indicate which student factored the trinomial completely and which student did not, and explain why.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
