Which of the following equations is of a parabola with a vertex at (1, -2)? O y = (x - 1)2 - 2
O y = (x - 1)2 + 2
O y = (x + 1)2 - 2
O y = (x + 1)2 - 2

y = (x-1)^2 - 2

Step-by-step explanation:

The parabola vertex point is always (h, k) in y = (x-h)^2 + k

All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
