Let G be a group of order 312. Apply Sylow's Theorem to prove that G has a normal p-subgroup for some prime p.

Answers

Answer 1

Sylow's Theorem states that for any prime factor p of the order of a group G, there exists a Sylow p-subgroup of G. Let n_p denote the number of Sylow p-subgroups in G. Then, n_p is congruent to 1 mod p and n_p divides the order of G. In the case of G with order 312, the prime factorization of 312 is 2^3 * 3 * 13. By Sylow's Theorem, there exists a Sylow 2-subgroup of order 8, a Sylow 3-subgroup of order 3, and a Sylow 13-subgroup of order 13. Since 8 and 13 are coprime, the number of Sylow 2-subgroups and Sylow 13-subgroups must be 1. Thus, both subgroups are normal in G.

Sylow's Theorem is a powerful tool in group theory that enables us to analyze the structure of a finite group by studying its subgroups. A Sylow p-subgroup of a group G is a maximal p-subgroup of G, i.e., a subgroup of G of order p^k, where k is the largest integer such that p^k divides the order of G. Sylow's Theorem states that for any prime factor p of the order of a group G, there exists a Sylow p-subgroup of G. Moreover, any two Sylow p-subgroups are conjugate in G, which means that they are essentially the same from the perspective of the group structure. This fact can be used to prove important results such as the existence of normal subgroups in G.

In the case of G with order 312, Sylow's Theorem guarantees the existence of Sylow 2-subgroups, Sylow 3-subgroups, and Sylow 13-subgroups. The number of Sylow p-subgroups for each prime factor p is determined by the congruence n_p ≡ 1 mod p and the divisibility n_p | |G|. Since 8 and 13 are coprime, it follows that the number of Sylow 2-subgroups and Sylow 13-subgroups must be 1. This implies that both subgroups are normal in G, which means that they are invariant under conjugation by elements of G. The existence of normal subgroups is a fundamental property of group theory that has many applications in algebra, number theory, and geometry.

Answer:If shoes are for all games in row,  P = 2 + 3 g   If not,  P = 5 g  ,with g the number of games

Explanation: The price depends:if shoes are included for the whole games, you just have to pay them once and then you have to pay  

g g a m e s , so  P ( g ) = 2 + 3 g   Else, you have to pay  g s h o e s  and  g b o w l p a r t y ,so  

P ( g ) = 2g + 3 g⇔ P ( g ) = 5 g

Find the frequency of a pendulum whose length is 1 foot and where the gravitational field is approximately 32 ft/s2 b. The strength of the gravitational field on the moon is about 1 6 as strong as on Earth. Find the frequency of the same pendulum on the moon.

Answers

Answer:

a. 0.9 Hz b. 0.37 Hz

Step-by-step explanation:

The frequency of the simple pendulum f = (1/2π)√g/l where g = acceleration due to gravity and l = length of pendulum

a. Find the frequency of a pendulum whose length is 1 foot and where the gravitational field is approximately 32 ft/s2

To find f on Earth, g = 32 ft/s² and l = 1 ft

So, f =  (1/2π)√(g/l)

f = (1/2π)√(32 ft/s²/1 ft)

f = (1/2π)√(32/s²)

f = (1/2π)(5.66 Hz)

f = 0.9 Hz

b. The strength of the gravitational field on the moon is about 1/6 as strong as on Earth.. Find the frequency of the same pendulum on the moon.

On the moon when acceleration due to gravity g' = g/6,

f =  (1/2π)√(g'/l)

f =  (1/2π)√(g/6l)

f = (1/2π)√[32 ft/s²/(6 × 1 ft)]

f = (1/2π)√(32/s²)/√6

f = (1/2π)(5.66 Hz)/√6

f = 0.9/√6 Hz

f = 0.37 Hz

Three pounds of flour are divided into 6 containers so that each container holds the same number of pounds of flour

Answers

Answer:

0.5 pounds per container.

Step-by-step explanation:

just divide 3 pound by 6 containers so it would be 3/6 which is equal to 1/2 which is the same as 0.5

There each container holds a number of pounds of flour which would be  0.5 pounds.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation.

If three pounds of flour are divided into 6 containers so that each container holds the same number of pounds of flour, we can find out how many pounds of flour each container holds by dividing the total amount of flour by the number of containers.

We can use the following equation to find out how many pounds of flour each container holds:

pounds of flour per container = total pounds of flour / number of containers

So, using this equation:

pounds of flour per container = 3 / 6

Apply the division operation, and we get

pounds of flour per container = 0.5

Each container holds 0.5 pounds of flour.

Options:

(c) 15 times the volume of the disk

(d) The height of the stack multiplied by [tex]\pi r^2[/tex]

Answer:

(b) [tex]\pi * 3* 15^2[/tex]

Step-by-step explanation:

Given

15 identical disks

[tex]r = 3cm[/tex]

[tex]h = 1cm[/tex]

Required

Determine the odd option

The volume of 1 disk is:

[tex]V_1 = \pi r^2h[/tex]

[tex]V_1 = \pi * 3^2 * 1[/tex]

The volume of 15 is:

[tex]V_{15} = 15 * V_1[/tex]

[tex]V_{15} = 15 * \pi * 3^2 * 1[/tex]

[tex]V_{15} = \pi * 3^2 * 15[/tex]

The above equation represents (a), (c) and (d)

Because:

(a):  [tex]V_{15} = \pi * 3^2 * 15[/tex]

(c) 15 * volume of the disk: [tex]V_{15} = 15 * V_1[/tex] = [tex]V_{15} = \pi * 3^2 * 15[/tex]

(d) height * [tex]\pi r^2[/tex] = h * [tex]\pi r^2[/tex] = [tex]15 * \pi * 3^2 * 1[/tex] = [tex]V_{15} = \pi * 3^2 * 15[/tex]

Hence, (b) is the odd option
