Answer:
Sara y sus abuelos necesitarán 6 botes.
Step-by-step explanation:
Primero, tienes que encontrar los gramos de cloro que necesitas para 600.000 litros de agua usando una regla de tres dado que sabes que se debe añadir 10 gr de cloro por cada 1.000 litros de agua:
1.000 litros → 10 gr
600.000 litros → x
x=(600.000*10)/1.000=6.000 gr de cloro
Ahora, tienes que encontrar a cuántos kg equivalen los 6.000 gr de cloro que necesitas teniendo en cuenta que 1 kg son 1.000 gr:
1 kg → 1.000 gr
x ← 6.000 gr
x=(6.000*1)/1.000= 6 kg
Finalmente, para saber cuántos botes se necesitan tienes que dividir los 6 kg entre 1 kg porque el cloro se vende en botes 1 kg:
6/1=6
De acuerdo a esto, Sara y sus abuelos necesitarán 6 botes.

<em>Quadratic equation, vertex shape, parabola
</em>
For this case we have to rewrite the given quadratic equation, in the form of vertex, for this, we must take into account that a quadratic equation of the form , can be rewritten in the form of vertex as: Vertice is the lowest or highest point of the parabola. The vertex is given by: . So, let: , to find the equation in the form of vertex, we follow the steps below:
Step 1:
We take the common factor to the first two terms of the equation:
Step 2:
We work square:
We divide the coefficient of the term by 2 and its result is squared, that is:
So, we have:
Step 3:
We simplify:
Step 4:
We factor:
Thus,
Answer:
The equation in the form of vertex is: , and the vertex is
