an example of an abelian group which is not cyclic

Answers

Answer 1

G=Z6×Z2G=Z6×Z2 will do (where ZnZn denotes the cyclic group of order nn). As a direct product of cyclic (so abelian) groups, GG is again abelian. Given any element (x,y)∈G(x,y)∈G, the order of (x,y)(x,y) will be the least common multiple of the orders of x,y.x,y.  

The order of xx must divide 66 and the order of yy must divide 2,2, so the order of (x,y)(x,y) is at most lcm(6,2)=6.lcm⁡(6,2)=6. But |G|=|Z6|⋅|Z2|=6⋅2=12.|G|=|Z6|⋅|Z2|=6⋅2=12. Since no element of GG has order 12,12, then GG is not cyclic.

Which one of the following is the same as 72 dekaliters ?


A. 72 dal


B. 72 dI


C. 72 deciliters


D. 72 ml

Answers

Answer:

72 dal

Step-by-step explanation:

short form to dekaliter is dal

Based on the abbreviations for various units of measurements, the best answer here is A. 72 dal

Units of measurements have shorter forms such as:

Liters ⇒ LMilliliter ⇒ MLDekaliters ⇒ DAL

As the short form of dekaliter is dal, the first option must be correct as it is the same as 72 dekaliters albeit in a shortened form.

We can therefore conclude that 72 dal and 72 dekaliters are the same.

The center of the circle whose equation is (x + 2)² + (y - 3)² = 25 is

Answers

Answer:

The center of the circle is at: C=(−2,3).

The radius of the circle is r=5.

Step-by-step explanation:

A circle with center at (h,k) and a radius of r has equation (x−h)2+(y−k)2=r2.

In this example our circle equation can be written as:

(x−(−2))2+(y−3)2=(5)2

So, we have: h=−2 , k=3 and r=5.

Answers

Answer:

dan

Step-by-step explanation:

to find out which person ate more, you have to convert the fractions into ones with the same denominator, or bottom number

the lcf (least common factor) of 7 and 4 is 28

6/7 * 4/4 = 24/28

3/4 * 7/7 = 21/28

using these numbers we can tell that dan ate more

Answer:

EquivalentNot EquivalentEquivalentNot Equivalent

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)

__

The left-side expressions (all the same) can be simplified to ...

  (7^(1/5))·(49^(7/5)) = (7^(1/5))·((7^2)^(7/5))

  = (7^(1/5))·(7^(14/5)) . . . . . . matches 3rd right-side expression

  = 7^(1/5 +14/5) = 7^(15/5) = 7^3

  = 343 . . . . . . . . . . . . . . . . . . matches 1st right-side expression

__

49 is obviously not equivalent to 343.

49^(2/10) is obviously not equivalent to 49^(7/5).
