Una foca tiene 1 , 500 nervios por bigote. Eso es 10 veces más que en una rata. ¿Cuántos nervios por bigote tiene una rata?

The height of the rectangular chest should be 2 feet.

To determine the height of the rectangular chest, we can use the formula for the volume of a rectangular prism:

Volume = Length * Width * Height

We are given that the length is 6 feet, the width is 2 feet, and the volume is 24 cubic feet. Let's substitute these values into the formula and solve for the height:

24 = 6 * 2 * Height

Dividing both sides of the equation by (6 * 2):

24 / (6 * 2) = Height

24 / 12 = Height

2 = Height

The equation for the instantaneous velocity, v(t), of the bumblebee at any point in time is v(t) = 12 - 18t²

To find the equation for the instantaneous velocity of the bumblebee at any point in time, we need to take the derivative of the distance function, p(t), with respect to time (t).

Given that p(t) = 12t - 6t³ + 1, we can find the derivative using the power rule of differentiation.

Derivative of p(t) with respect to t:

p'(t) = d/dt (12t - 6t³ + 1)

= 12 - 18t²

Therefore, the equation for the instantaneous velocity, v(t), of the bumblebee at any point in time is:

v(t) = 12 - 18t²

Arithmetic sequence and Geometric sequence a₁ is an integer, the numerator must be divisible by -21.

Let's denote the common difference of the arithmetic sequence as 'd' and the common ratio of the geometric sequence as 'r'.

Since a4, a7, and a12 form a geometric sequence, we can express the terms as follows:

a4 = a₁ + 3d

a7 = a₁ + 6d

a12 = a₁ + 11d

We know that a7 = 30, so we can substitute it into the equation:

a₁ + 6d = 30

Now, let's examine the ratio between consecutive terms in the geometric sequence:

(a7 / a4) = (a12 / a7)

Substituting the expressions for the terms, we get:

[(a₁ + 6d) / (a₁ + 3d)] = [(a₁ + 11d) / (a₁ + 6d)]

Cross-multiplying, we have:

(a₁ + 6d)(a₁ + 6d) = (a₁ + 3d)(a₁ + 11d)

Expanding the equation, we get:

a₁² + 12ad + 36d² = a₁² + 14ad + 33d²

Simplifying and rearranging terms, we obtain:

2ad = -3d²

Since the sequence is non-constant, the common difference 'd' cannot be zero. Therefore, we can divide both sides of the equation by 'd':

2a = -3d

Substituting the value of 'd' from the equation a₁ + 6d = 30, we have:

2a = -3(a₁ + 6d)

Expanding and simplifying:

2a = -3a₁ - 18d

Now, we can substitute the value of 'd' from the equation a₁ + 6d = 30:

2a = -3a₁ - 18(a₁ + 6d)

Expanding and simplifying further:

2a = -3a₁ - 18a₁ - 108d

Since a₁ + 6d = 30, we can substitute it again:

2a = -3a₁ - 18a₁ - 108(a₁ + 6d)

Expanding and simplifying:

2a = -3a₁ - 18a₁ - 108a₁ - 648d

Combining like terms:

2a = -129a₁ - 648d

Now, we can substitute the known value of a₇ = 30 into the equation a₁ + 6d = 30:

a₁ + 6d = 30

Rearranging the equation:

a₁ = 30 - 6d

Substituting this into the previous equation:

2a = -129(30 - 6d) - 648d

Expanding and simplifying:

2a = -3870 + 774d - 648d

Combining like terms:

2a = -3870 + 126d

Now, we can substitute the value of 2a = -3a₁ - 18a₁ - 108d into the equation:

-3a₁ - 18a₁ - 108d = -3870 + 126d

Expanding and simplifying:

-21a₁ - 108d = -3870 + 126d

Rearranging the equation:

-21a₁ = 234d - 3870

Dividing both sides by -21:

a₁ = (234d - 3870) / -21

Since arithmetic sequence and geometric sequence a₁ is an integer, the numerator must be divisible by -21

The statement is saying that the Separation Axioms are not strong enough to develop set theory with its usual operations and constructions.

The Separation Axioms are a set of axioms that allow us to define subsets of sets. However, they are not strong enough to allow us to define the union of two sets, or the notion of a real number.

The union of two sets is the set that contains all the elements that are in either set, or in both sets. For example, the union of the set {1, 2, 3} and the set {4, 5, 6} is the set {1, 2, 3, 4, 5, 6}.

A real number is a number that can be represented on a number line. Real numbers include all the rational numbers (numbers that can be written as a fraction of two integers), as well as all the irrational numbers (numbers that cannot be written as a fraction of two integers).

The Separation Axioms are not strong enough to define the union of two sets or the notion of a real number because they do not allow us to define arbitrary subsets of sets. For example, the Separation Axioms do not allow us to define the subset of all real numbers that are greater than 0.

The statement that explains why some elements decay and others do not is: "Elements that decay have a proton to neutron ratio that is too high or too low."

Decay of elements refers to the process of spontaneous transformation where an unstable atomic nucleus undergoes a change, often resulting in the emission of radiation or the formation of a new element.

The stability of an atomic nucleus depends on the balance between the strong nuclear force, which holds protons and neutrons together, and the electromagnetic force, which repels protons due to their positive charge.

Elements with a proton to neutron ratio that is too high or too low are generally more likely to decay.

This is because the imbalance in the ratio affects the stability of the nucleus.

A high proton to neutron ratio means that there are more protons than neutrons, leading to increased electrostatic repulsion between protons. On the other hand, a low proton to neutron ratio means there are more neutrons than protons, which can result in an unstable nucleus.

To achieve a more stable configuration, elements with an imbalanced proton to neutron ratio can undergo radioactive decay processes such as alpha decay, beta decay, or gamma decay.

These processes help the nucleus reach a more favorable balance of protons and neutrons, ultimately increasing its stability.

It's important to note that not all elements with an imbalanced proton to neutron ratio decay.

Some isotopes may have a slightly unstable configuration but still exist for long periods or even indefinitely.

The specific factors contributing to the stability or decay of an element involve the exact balance of nuclear forces, the energy differences between nuclear configurations, and other considerations that are governed by the fundamental laws of physics.

To pack six chocolate bars to take up as little room as possible, we can arrange them in two layers of three bars each. Here is a sketch of one possible way to pack six chocolate bars:

```

_______ _______ _______

| || || |

| C || C || C |

|_______||_______||_______|

| || || |

| C || C || C |

|_______||_______||_______|

```

In this arrangement, the bars are packed tightly together and take up the least amount of space.

To find the size of the box needed for 48 chocolate bars, we first need to find the volume of one chocolate bar. The dimensions of each chocolate bar are given as 2.1 cm x 3 cm x 12 cm, so the volume is:

V = l x w x h = 2.1 cm x 3 cm x 12 cm = 75.6 cm^3

To pack 48 chocolate bars, we need to find the total volume they occupy:

Total volume = 48 x V = 48 x 75.6 cm^3 = 3,628.8 cm^3

Since the chocolate bars are packed into cuboid-shaped boxes, we need to find the dimensions of the box that can accommodate the total volume of the bars. Let's call the length, width, and height of the box L, W, and H, respectively. Then we have:

L x W x H = 3,628.8 cm^3

We want to find the smallest possible box, so we need to minimize each of the dimensions. We can start by setting two of the dimensions equal to each other and solving for the third. Let's set L = W and solve for H:

L x L x H = 3,628.8 cm^3

H = 3,628.8 cm^3 / L^2

Substituting L = W, we get:

H = 3,628.8 cm^3 / W^2

Now we can express the volume of the box in terms of just one variable:

L x L x H = L^2 x H = L^2 x (3,628.8 cm^3 / L^2) = 3,628.8 cm^3

Simplifying, we get:

L^3 = 3,628.8 cm^3

Taking the cube root of both sides, we get:

L = 16 cm (rounded to the nearest whole number)

So the length and width of the box should be 16 cm, and the height can be calculated as:

H = 3,628.8 cm^3 / (16 cm x 16 cm) = 14.2 cm (rounded to one decimal place)

Therefore, a box with dimensions 16 cm x 16 cm x 14.2 cm can accommodate 48 chocolate bars packed as described earlier.
