Taking into account the definition of permutation, there are 1320 ways you can listen to 3 songs from a cd that has 12 selections.

Permutations refer to the action of arranging all the members of a set in some kind of order or sequence. This means that if a set is already ordered, the process of rearranging its elements is called permutation.

In other words, permutations of m elements in n positions are the different ways in which the m elements can be arranged occupying only the n positions.

In this case, the elements are not repeated, since if they are repeated or equal to each other, exchanging them does not generate a new permutation. And the order does matter, since the exchange between two different elements generates a new permutation

To obtain the total of ways in which m elements can be placed in n positions, the expression is used:

[tex]P=\frac{m!}{(m-n)!}[/tex]

The sign ! indicates the factorial function, which indicates that all positive integers between the number that appears in the formula and the number 1 must be multiplied.

The order in which songs are listening is important as there is no plan to listen to the same song twice. So, the permutation can be applied.

Being:

and replacing in the expression for permutation, you get:

[tex]P=\frac{12!}{(12-3)!}[/tex]

[tex]P=\frac{12!}{9!}[/tex]

[tex]P=\frac{479001600}{362880}[/tex]

P= 1320

The angle generated by the hour hand measures -270° or -4.71 radians, and we will see that the angle generated by the minute hand is 12 times the one generated by the hour hand.

Remember that in a complete rotation we have an angle of 360°, and in a complete rotation we have 12 hours, then there is a relation:

12 hours = 360°

1 hour = 360°/12 = 30°

From 9:00 a.m to 5:00 p.m. there are 9 hours, so the angle that the hour hand does is:

A = 9*(30°) = -270°

(the negative sign is because this angle is measured clockwise)

Now we can write this in radians, remember that:

3.14 radians = 180°

Then:

1 = (3.14 rad/180°)

Then:

270° = -270°*(3.14 rad/180°) = -4.71 rad

Each hour that passes, the minute hand does a complete revolution. Then in 9 hours, the minute hand does an angle of:

A = 9*(-360°) = -3,240°

To compare this angle to the one generated by the minute hand we take the quotient:

-3,240°/-270° = 12

So this angle generated by the minute hand is 12 times the one generated by the hour hand.

Based on the model of cellular transport, the transport of a substance against its electrochemical gradient is accomplished with energy input from ATP.

It is a cellular mechanism by which some molecules cross the plasma membrane against a concentration gradient with the consequent expenditure of energy.

The carrier proteins that intervene in the transport of molecules require an energy supply, in the form of ATP, it is carried out at the expense of respiration and photosynthesis processes; by hydrolysis of ATP by membrane ATP hydrolases.

Therefore, we can conclude that based on the model of cellular transport, the transport of a substance against its electrochemical gradient is accomplished with energy input from ATP.

The table is an illustration of arithmetic sequence

The equation of the arithmetic sequence is B(s) = 7.5s

From the table (see attachment), we have the following formula

B(s) = 7.5s

For s =0 to 4, we have:

B(0) = 7.5(0) = 0

B(1) = 7.5(1) = 7.5

B(2) = 7.5(2) = 15

B(3) = 7.5(3) = 22.5

B(4) = 7.5(4) = 30

So, the complete table is:

The reaction rate between 0 -195 seconds for the decomposition of N2O5 is 0.0006 M/s.

The rate of reaction can be estimated in terms of the consumption of the reactants in the reaction.

From the given information, the equation N2O5 has been the reactant that has been used in 2 moles.

The rate of the reaction is expressed as:

[tex]\mathbf{Reaction \ rate = -\dfrac{1}{2} \times \dfrac{dN_2O_5}{dt}}[/tex]

The reaction rate for a time interval between (0 - 195) sec is expressed as follows:
