Answer:
Con cada depósito se pueden llenar 3,617.28 envases.
Step-by-step explanation:
Dado que el agua de un manantial se conduce hasta unos depósitos cilíndricos que miden 12 m de radio de la base y 20 m de altura, y luego se embotella en bidones de 2.5 litros, para determinar cuántos envases se llenan con cada depósito se debe realizar el siguiente cálculo, sabiendo que el volumen de un cilindro se obtiene multiplicando pi por el radio del cilindro al cuadrado por su altura:
3.14 x (12x12) x 20 = X
3.14 x 144 x 20 = X
452.16 x 20 = X
9,043.2 = X
9,043.2 / 2.5 = X
3,617.28 = X
Por lo tanto, con cada depósito se pueden llenar 3,617.28 envases.
For the given parabola, the axis of symmetry is x = 2.
<h3>
How to get the axis of symmetry?</h3>
For any given parabola, we define the axis of symmetry as a line that divides the parabola in two equal halves.
For a regular parabola, we define the axis of symmetry as:
x = h
Where h is the x-component of the vertex.
Remember that for the general parabola:
y = a*x^2 + b*x + c
The x-value of the vertex is:
h = -b/(2a)
Then for the function:
f(x)=−2x²+8x−2
We get:
h = -8/(2*-2) = 2
Then the axis of symmetry is x = 2.

The values of x for which the denominator is equal to zero is +2 or -2-2
<h3 /><h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given function is: y=
As, for the denominator is equal to zero. We have
x²-4=0
x²=4
x=√4
x= ± 2
Thus, by putting either x= +2 or x= -2 in denominator which will gives the denominator equals to zero.

Answer: d) 2.5
<u>Step-by-step explanation:</u>
The mean is 16 so it has a z-score is 0
The standard deviation is 4 so:
- z-score of 1 is: 16 + 4 = 20
- z-score of 2 is: 20 + 4 = 24
- z-score of 3 is: 24 + 4 = 28
Notice that 26 is between the z-scores of 2 and 3 = 2.5
