The value of each letter in the given magic square is a = 30, b = 6 , c = 18 and d = 4.

<h3>What is a magic square?</h3>

A magic square is one that has several different integers placed in such a way that the sum or total of the numbers is the same on all of the diagonals, as well as in every row, column, and major diagonal.

Given:

A magic square where all rows, columns, and diagonals sum to the same number.

Sum of the numbers in the diagonal of the magic square,

5 + 17 + 29 = 51

In the first row, the sum of numbers will also be 51

5 + a + 16 = 51

a = 51 - 21 = 30

Similarly, the sum in the first column

5 + 28 + c = 51

c = 51 - 33 = 18

And the sum in the last row,

c + d + 29 = 51

Putting the value of c, we get

18 + d + 29 = 51

d = 51 - 47 = 4

Now to find the value of b the sum of the last column,

16 + b + 29 = 51

b = 51 - 45 = 6

A ligament is a band of tough tissue connection bones or holding organs in place

timurjin [86]

<h2><u>Full Question:</u></h2>

Which definition for a ligament did you think was better? Explain. 1- A ligament is made up of tissue that forms a band. 2- A ligament is a band of tough tissue connecting bones or holding organs in place.

<h2><u>Answer:</u></h2>

A ligament is a band of tough tissue connecting bones or holding organs in place is the better definition.

Option B

<h3><u>Step-by-step explanation:</u></h3>

Ligament is a type of connective tissue which develops from the mesoderm. Its actually a tough band containing mostly collagen tissue. Ligament joins two bones which forms a joint.

Ligament is formed of collagen fibres which run parallel to each other and this forms a band. It's very tough and this is why, it can hold bones together.

Ligaments that hold organs are actually pseudo ligaments which are actually folds of peritonium that holds the organs in place.

the sequence {a_n} is defined by a_1= 1 and a_(n+1) = 1/2( a_n+ (4/a_n) ) for >=1. Assuming that {a_n} converges, find its li

katen-ka-za [31]

$a_{n+1}=\dfrac{a_n+\frac4{a_n}}2$

Assuming convergence of the sequence, we have $a_n\to L$ for some limit $L$ as $n\to\infty$ . This also means $a_{n+1}\to L$ . So in the above equation, we can substitute and solve for $L$ :

$L=\dfrac{L+\frac4L}2$

$\implies2L^2=L^2+4$

$\implies L^2=4\implies L=\pm2$

The limit can only be one of these values; otherwise, the sequence would be divergent. To decide which one is correct, we can observe that the sequence is strictly positive. So $L=2$ .
