Answer:
27
Step-by-step explanation:
We have that

we know that
Is the equation of a vertical parabola open down
so
the vertex is a maximum
step 1
convert the equation of the parabola in the vertex form

the vertex (h,k) is the point (0,36)
Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)
Part b) The points on the graph where the height of the tunnel is zero feet is when y=0
so
for y=0

the points are (-6,0) and (6,0)
see the attached figure
Step-by-step explanation:
That is because 1/3 is not exactly equal to 0.333333. 0.333333 is a rounded number from the real number which 0.3 and the 3 goes on forever. In the image it show the the answer, in where the 3 goes on forever.
Answer:
Quedan 2.083 m^3 de agua en el reservorio.
Equivalen a 2083 litros.
Step-by-step explanation:
Los dueños del restaurante tienen un reservorio de agua cuyo volumen es de 6.25 m^3.
Si han utilizado 2/3 del reservorio, esto implica que aún quedan en el reservorio una tercera parte del volumen original (1/3).
Entonces, la cantidad de metros cúbicos (m^3) de agua que quedan en el reservorio se puede calcular como:

Este valor equivale a un volumen en litros de:

I think you probably divide 7,200 gallons by 81 gallons since it's asking how many in one.
