PLS HELP Find the equation of a parabola with vertex at the origin and focus (0, –32).

x2 = –32y
x2 = –128y
y2 = –128x
x2 = 128y

What are correct trigonometric ratios that could be used to determine the length of ln

The triangles are similar. what is the value of x? show your work.

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
