Answer:

Step-by-step explanation:
we have

This is the equation of a vertical parabola open upward
The vertex is a minimum
The equation of a vertical parabola in vertex form is equal to

where
(h,k) is the vertex
Convert the given function to vertex form
Factor the leading coefficient

Complete the square


Rewrite as perfect squares
------> equation in vertex form
The vertex is the point (2,6)
Answer:
Yes. Ponds can have gallons of water. 16 oz could be the weight of a loaf of bread.
[1], [3] => a = 49,000/2 = 24,500 => b +c = 24,500 => c = 24,500 - b;
[2] => 25*24,500 + 20b + 15c = 1,052,000 => 20b + 15c = 1,027,500;
20b + 15*(24,500 - b) = 1,027,500 => 5b = 733,500 => b = 146,700 =>
c = - 122,200;
For this case we have by definition, that the total surface area of a regular pyramid with a square base is given by:

Where:
p: It is the perimeter of the base
S: It's the inclination
It is the area of the base
Substituting:

ANswer:
Option B
