How many ways can you listen to 3 songs from a cd that has 12 selections?

Answers

Answer 1

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

What is permutation

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.

Number of ways you can listen to 3 songs

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:

m=12n=3

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

Finally, there are 1320 ways you can listen to 3 songs from a cd that has 12 selections.

Use the mean value theorem to prove the inequality

Answers

Answer:

Proving inequalities, you often have to introduce one or more additional terms that fall between the two you're already looking at. This often means taking away or adding something, such that a third term slides in. Always check your textbook for inequalities you're supposed to know and see if any of them seem useful.

Twelve identical point charges q are equally spaced around the circumference of a circle of radius r. the circle is centered at the origin. one of the twelve charges, which happens to be on the positive x axis, is now moved to the center of the circle.

Answers

There is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.

What is a line charge?

A line charge refers to the charge that is allocated along a curve that is one dimensional in nature such as a circle.

In physics experiments, line charges are used in wire chambers. Wire chambers are used for high-energy physics experiments.

In summary, the charges are put at equal distances around the circumference of the circle in the example.

Because the charges at the opposing ends of the circle are similar, they exert an equal-magnitude repelling force in the opposite direction on the charge at the center of the circle, thus balancing out the forces.

This is why there is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.

The horizontal part of a step is called the tread. the vertical part is called the riser. the recommended riser-to-tread ratio is 7 inches : 11 inches. a. find the value of x for stairs built using the recommended riser-to-tread ratio. round your answer to the nearest tenth.

Answers

The value of x for these stairs built by using the recommended riser-to-tread ratio is 32.5°.

Given the following data:

Length of riser = 7 inches.Length of tread = 11 inches.Ratio = 7:11.

How to determine the value of x.

In Mathematics, a tread refers to the horizontal part of a step while a riser is the vertical part of a step.

Note: Let the angle of inclination be x.

In Geometry, two (2) lines that are parallel have the same alternate interior angles. Thus, the angle of inclination between the riser and tread is given by:

[tex]Tan x = \frac{rise}{tread} \\\\Tan x = \frac{7}{11} \\\\Tan x = 0.6364\\\\x=tan^{-1}0.6364[/tex]

x = 32.5°.

A driver of a 1 000 kg jeepney travelling at a speed of 16,7 m/s bound for divisoria applies the car's brakes when he sees a red light along recto avenue. the car's brakes provide a frictional force of 8 000 n. determine the stopping distance of the car.

Answers

The stopping Distance of the Car with the given parameters is; 17.43 m

What is the stopping sight distance?

We are given;

mass; m = 1 000 kg

speed; u = 16.7 m/s

Frictional force; F = 8000 N

distance, s  = ?

final velocity = 0 m/s (car stops)

Formula for final velocity is;

v² = u² + 2as

but a = negative (deceleration)

And F = ma

Thus;

a = F/m = 8000/1000

a = 8 m/s²

Thus;

0 = (16.7)² - 2(8)(s)
