Para determinar los elementos de la parábola con la ecuación general x^2 - 12x + 10y - 4 = 0, primero necesitamos convertirla a su forma estándar completa. La ecuación general de una parábola es de la forma Ax^2 + Bx + Cy + D = 0.

Dada la ecuación x^2 - 12x + 10y - 4 = 0, vamos a completar el cuadrado para x y despejar y:

1. Pasamos los términos con x a un lado y los términos independientes al otro lado de la ecuación:
x^2 - 12x + 10y = 4

2. Completamos el cuadrado para x:
(x^2 - 12x + 36) + 10y = 4 + 36
(x - 6)^2 + 10y = 40

3. Despejamos y:
10y = - (x - 6)^2 + 40
y = -\frac{1}{10}(x - 6)^2 + 4

Ahora que hemos convertido la ecuación general a la forma estándar completa, podemos identificar los elementos de la parábola:

- Vértice: (h, k) = (6, 4)
- Eje de simetría: x = 6
- Distancia focal: |p| = \frac{1}{4a} = \frac{1}{4(1/10)} = 2.5
- Foco: (h, k + p) = (6, 4 + 2.5) = (6, 6.5)

Graficando la parábola:
\begin{array}{ c }\begin{tikzpicture} \begin{axis}[ axis lines = center, xlabel = x, ylabel = y, xmin = 0, xmax = 12, ymin = 0, ymax = 10, ] \addplot [ domain=0:12, samples=100, color=blue, ] {-1/10*((x-6)^2)+4}; \addplot [only marks, mark=*] coordinates {(6,4) (6,6.5)}; \end{axis}\end{tikzpicture}\end{array}

\textbf{Respuesta: } La parábola tiene vértice en el punto (6, 4), eje de simetría en x = 6, una distancia focal de 2.5 y su foco se encuentra en el punto (6, 6.5).

A construction company is working on two projects: house construction and building construction. Each house requires 4 weeks of work and produces a profit of $50,000. Each building requires 8 weeks of work and produces a profit of $100,000. The company has a total of 24 work weeks available. Furthermore, it is known that at least 2 houses and at least 1 building must be built to meet the demand. The company wants to maximize its profits and needs to determine how many houses and buildings it should build to meet demand and maximize profits, given time and demand constraints.
