Answer:
Equation in square form:

Extreme value:

Step-by-step explanation:
We are given

we can complete square

we can use formula


now, we can add and subtract 5^2



So, we get equation as

Extreme values:
we know that this parabola
and vertex of parabola always at extreme values
so, we can compare it with

where
vertex=(h,k)
now, we can compare and find h and k

we get
h=-5
k=-4
so, extreme value of this equation is

The answer is 1:11. After it being simplified from 6:66. Hope this helps.
point A (-1-1) point B(-2-1)
The answer will be 15-4=11
For cylinders to be similar, the ratio between their height and radius must be equal.Our cylinder's ratio is :

The only cylinder with same ratio is the one at the choice B.
