HELP PLEASE A mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror. The pipe is located 2 inches from the vertex of the mirror. Write an equation of the parabola that models the cross section of the mirror. Assume that the parabola opens upward.

    height of the parabola in inches: Take the formula to be y = ax^2 The focus of the parabola is 2 inches up, which means a/4 = 2 ==> a = 8... the equation is: y = 8x^2

    Replace the 2 with a 6. Which means a/4 = 2 ==> a = 8. |||||| a/4 = 6 ==> a = 24. y = 24x^2

    Yeah, I believe so. I think it's just the formula. I'll check very quickly for you tho.

    Whoops, y = ax^2 is the formula, I guess whatever the 'x' is, but at least you have the answer. Off to other post, later, welcome.
