The area of the cylinder is a function of its height (h) and radius, ([tex]\mathbf{4\sqrt 3}[/tex])

The exact value of h is: [tex]\mathbf{7\sqrt 2- 4\sqrt 3}[/tex]

The given parameters are:

[tex]\mathbf{Area =56\pi\sqrt 6}[/tex]

[tex]\mathbf{r=4\sqrt 3}[/tex]

The surface area of a cylinder is calculated as:

[tex]\mathbf{Area = 2\pi rh + 2\pi r^2}[/tex]

Substitute values for Area

[tex]\mathbf{56\pi\sqrt 6= 2\pi rh + 2\pi r^2}[/tex]

Divide through by pi

[tex]\mathbf{56\sqrt 6= 2 rh + 2r^2}[/tex]

Substitute value for r

[tex]\mathbf{56\sqrt 6= 2 (4\sqrt 3)h + 2(4\sqrt 3)^2}[/tex]

[tex]\mathbf{56\sqrt 6= 8h\sqrt 3 + 2\times 48}[/tex]

[tex]\mathbf{56\sqrt 6= 8h\sqrt 3 + 96}[/tex]

Collect like terms

[tex]\mathbf{8h\sqrt 3 = 56\sqrt 6- 96}[/tex]

Make h the subject

[tex]\mathbf{h = \frac{56\sqrt 6}{8\sqrt 3}- \frac{96}{8\sqrt 3}}[/tex]

[tex]\mathbf{h = 7\sqrt 2- \frac{12}{\sqrt 3}}[/tex]

Rationalize

[tex]\mathbf{h = 7\sqrt 2- \frac{12\sqrt 3}{3}}[/tex]

[tex]\mathbf{h = 7\sqrt 2- 4\sqrt 3}[/tex]

Hence, the exact value of h is: [tex]\mathbf{7\sqrt 2- 4\sqrt 3}[/tex]

To make pastry for an apple pie, you need 4 oz flour and 2 oz fat. The ratio of flour to fat is

4 : 2 .

But this ratio can be simplified in the same way that two fractions can be simplified. We just

cancel by a common factor. So

4 : 2 = 2 : 1 .

Using multiplication signal rules, it is found that:

A: Emma's statement is always false.

B: The result is always negative.

C: Emma's statement is always true.

The rule used for this exercise is as follows:

Part A:

Two examples are:

[tex]-2.5(-3.8)(-2) = 9.5(-2) = -19[/tex]

[tex]-2.5(-2)(-0.7) = 5(-0.7) = -3.5[/tex]

Part B:

The rule is that the result is always negative.

Part C:

Two examples are:

[tex]-2.5(-3.8)(2) = 9.5(2) = 19[/tex]

[tex]-2.5(-2)(0.7) = 5(0.7) = 3.5[/tex]

The total time that should be taken by him to finish the book is 3.9 hours.

Given that,

Based on the above information, the time taken should be

[tex]= 375 \times 20 \div 32[/tex]

= 234.375 minutes

Now in hours it should be

[tex]= 234.375 \div 60[/tex]

= 3.9 hours

Therefore we can conclude that the total time that should be taken by him to finish the book is 3.9 hours.

Step-by-step explanation:

Las medidas o parámetros que se sitúan hacia el centro de un conjunto de valores, con el objetivo de analizar un análisis profundo de los resultados, son denominadas "medidas de tendencia central".

Una medida de tendencia central da una impresión del centro de una cantidad de datos o una distribución. Dependiendo de la medida de centro utilizada, el centro puede significar el centro de los datos o la distribución, o el lugar más probable donde se encuentran la mayoría de los datos.

Por tanto, una medida de centro da una impresión de los datos o la distribución en un número y, a veces, también se utiliza como un resumen de un solo número de los datos o la distribución. Las medidas conocidas del centro son la media aritmética y geométrica, la mediana, la moda y el centro del rango (el valor exactamente entre los valores mínimo y máximo).

Answer: This is a trig relationship from one of our special triangles, the 30-60-90 triangle.

Tan x = the opposite side of angle x divided by the adjacent side of angle x

The tangent is √3 when x = 60° or π/3

However, in this problem the value of the tangent is negative. In which of the four quadrants is the tangent function negative?

This function is negative in the second and fourth quadrants or when x = 120 and 300 degrees (or 2pi/3 and 5pi/3)

***I am assuming that the negative sign should be outside of the square root sign***

Answer: The guideline doesn’t account for students who may need to spend more—or less—time on assignments. In class, teachers can make adjustments to support struggling students, but at home, an assignment that takes one student 30 minutes to complete may take another twice as much time—often for reasons beyond their control.
