If u(x) = x^2 – x^4 + x^2 and v(x) = –x2, which expression is equivalent to (u/v)(x)? x^3 – x^2 –x^3 + x^2 –x^3 + x^2 – 1 x^3 – x^2 + 1

(u/v)(x) =

x^2 - x^4 + x^2

= - (1 - x^2 + 1) = - (2 - x^2).

        -x^2

I'd suggest you double check to ensure that you've copied down this problem correctly.

im sorry but no. i just need to answer for 50 poonts oof

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)
