To find the vertex of the parabola, we need to write it in a vertex form.
y=x² - 8x +12
1) complete the square
y=x² - 8x +12
y = x² -2*4x + 4² - 4² +12
y=(x-4)² -16 +12
2) calculate and write a vertex
y=(x-4)² -16 +12
y=(x-4)² - 4
(x-4) ----- x- coordinate of the vertex x=4
y=(x-4)² - 4 -------y- coordinate of the vertex y = - 4
Vertex is (4, -4).
Answer is (4, -4). No correct answer is given in choices.

Answer:
For a rectangular prism-like swimming pool: .
when
,
and
.
Step-by-step explanation:
Let assume that swimming pool has a rectangular base and depth is the same at any point at the bottom. In addition, let and
be the width and length of the swimming pool. Then, the volume needed to fill the swimming pool is:
, where
is the depth of the pool.
Let be ,
and
. The volume of the swimming pool is:
