12x^9y^4/6x^3y^2

A. 2x^3y^2
B. 2/x^6y^2
C. 2/x^3y^2
D. 2x^6y^2

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)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

other answer is correct. i had used the radius of the radius somehow. a website:
