I need all these before the morning!! For 20 points

Marta_Voda [28]

Answer:

15) Option B. 3

16) Option H. 144

17) Option B. -21

18) Option H. a^4 + 2

19) Option E. -18

20) Option G. 60

Step-by-step explanation:

15) 217/4 = 54 with a remainder of 1

217 = 4 ⋅ 54 + 1

So, the 217th digit after the decimal point of 0.3456 is one of the 4n+1st digits (with n=54) and must be 3.

16) a = 1/2, p = 1/16 * 48^2

= 144cm^2

17) when you solve the equation x^2 + 4x - 21 = 0 you get two solutions.

one is x = 3 and the second one is x = -7. The question is asking for the product so you will multiply these two x values. 3 * -7 = -21.

18) the factors of a^16 - 16 are: (a^8 + 4) (a^4 + 2) (a^4 -2)

Out of these factors that we get, (a^4 + 2) is the only polynomials listed in the answer choices.

19) 2n - 5 / n when n = 1/4

= 2(1/4) - 5 / 1/4

= -18

20) The machine is reading 40 pages in 1 hour, how many will it read in 90 minutes?

So, there are 60 minutes in an hour and the machine is reading 40 pages in 60 minutes. Meaning it is reading 20 pages in half an hour. So 20 + 20 = 40, so we are correct, the machine is indeed reading 20 pages in 30 mins. 90-60 mins = 30 mins.

How many pages is it reading in 30 mins? 20 right. So 40 + 20 = 60

The machine will read 60 pages in 90 mins.

State the Lagrange Theorem, and find the order of all possible subgroups of a group of order 5. The same question of a group of

oksian1 [2.3K]

Answer:

Lagrange Theorem

Step-by-step explanation:

The Lagrange Theorem:

Let G be a finite group and T be a subgroup of G. Then the order of T divides the Order of group G.

This can be written as:

If $T \subset G$ , then, $o(T)|o(G)$ .

Possible Subgroups

Now, we are given a group with order 5. We have to find all possible subgroups.

So, the possible subgroup are: groups with order 1, group with order 5

We are given a group with order 6.

Possible subgroups are: group of order 1, group of order 2, group of order 3 and group of order 4.
