A town is using a storage container in the shape of an inverted cone to

Mathematics

Vaselesa [24]2 years ago
7 0

Using the volume of the cone, it is found that:

Height and diameter are both 33.7 feet.

---------------------------

The volume of a cone with height h and diameter d is given by:

V = \frac{\pi d^2h}{12} = \frac{3.1415 d^2h}{12}

In this question:

  • Diameter and height equal, thus d = h.
  • Volume of 10,000 cubic feet, thus V = 10000

10000 = \frac{3.1415h^3}{12}

3.1415h^3 = 120000

h^3 = \frac{120000}{3.1415}

h^3 = 38197.19

h = \sqrt[3]{38197.19}

h = 33.7

Thus, both are 33.7 feet.

A regular octagon has an apothem measuring 10 in. and a perimeter of 66.3 in. What is the area of the octagon, rounded to the ne
Lerok [7]

Answer:

332in^2

Step-by-step explanation:

The area of a regular polygon is calculated using the formula;

Area=\frac{1}{2}ap

where a is the apothem and p is the perimeter.

It was given that, the apothem is, a=10in. and the perimeter is p=66.3 in.

We substitute into the formula to obtain;

Area=\frac{1}{2}\times10\times66.3in^2

Area=331.5in^2

To the nearest square inch, we have;

Area=332in^2

If f(x) = -3x + 4, find f(3x + 3)
Alex17521 [72]

Remark

What this is telling you to do is put 3x + 3 in the question wherever there was an x to start with.

Solution

f(x) = -3x + 4

f(3x + 3) = - 3(3x + 3) + 4

f(3x + 3) = -3*3x + (-3)*(3) + 4

f(3x + 3) = - 9x - 9 + 4

f(3x + 3) = -9x - 5 <<<<< Answer

Una persona camina 7 kilómetros hacia el norte, después 3 kilómetros hacia el este y, luego, 3 kilómetros hacia el sur. ¿A qué d
qaws [65]

Answer:

La persona está a 5 kilómetros con respecto al punto de partida.

Step-by-step explanation:

Considérese que la dirección norte coincide con el semieje +y y que la dirección este coincide con el semieje +x. A continuación, obtenemos las formas vectoriales equivalentes de cada afirmación:

(i) Una persona camina 7 kilómetros hacia el norte:

\vec r_{1} = 7\,\hat{j}\,[km]

(ii) Después 3 kilómetros hacia el este:

\vec r_{2} = 3\,\hat{i}\,[km]

(iii) Y luego, 3 kilómetros hacia el sur:

\vec r_{3} = -3\,\hat{j}\,[km]

El vector resultante de desplazamiento se construye a partir de la siguiente suma de vectores:

\vec R = \vec r_{1}+\vec r_{2} + \vec r_{3} (1)

\vec R = 3\,\hat{i} + 4\,\hat{j}\,[km]

Asumiendo que la distancia coincide con el desplazamiento resultante, calculamos la distancia con respecto al punto de partida mediante el Teorema de Pitágoras:

\|\vec R\| = \sqrt{3^{2}+4^{2}}

\|\vec R\| = 5\,km

La persona está a 5 kilómetros con respecto al punto de partida.

A bag contains 11 numbered chips inside. Two chips are labeled 1, three are labelled 2, and six are labelled 3. Let the random v
Dima020 [189]

Answer: 2.36

Step-by-step explanation:

Using the μ=∑[x⋅P(X=x)

U will need to do

2/11 because you have 2 labeled 1

3/11 because you have 3 labeled 2

6/11 because you have 6 labeled 3

Then you will do:

1 x 2/11 = 0.18

2 x 3/11 = 0.5454 = 0.55

3 x 6/11 = 1.63

Then add them all together to find the μ

0.18 + 0.55 + 1.63 = 2.36

Hope that helps, plz put a good rating
