Linear, when you plot the numbers it will be in a line. Remember “(line)ar”

a. 01011111110110010111

b. 0110000100001010

c. 1010101111001101

d. 0000000100000000

Explanation:

In the conversion from hexa decimal to binary, we know that 1 bit of a hexa decimal number is 4 bits of its binary equivalent. so here, in each one bit we will have a binary equivalent bit in group of 4 against each one, starting from LSB:

a. 5FD97:

The binary equivalent of each:

5 = 0101

F = 1111

D = 1101

9 = 1001

7 = 0111

Therefore, the bit pattern for it is:

5FD97 = 01011111110110010111

b. 610A:

6 = 0110

1 = 0001

0 = 0000

A = 1010

Therefore, the bit pattern for it is:

610A = 0110000100001010

c. ABCD:

A = 1010

B = 1011

C = 1100

D = 1101

Therefore, the bit pattern for it is:

ABCD = 1010101111001101

d. 0100:

0 = 0000

1 = 0001

0 = 0000

0 = 0000

Therefore, the bit pattern for it is:

0100 = 0000000100000000

The bit pattern 3.6.9 in dotted decimal notation can be represented as follows: 00000011.00000110.00001001 Each number is converted to equivalent binary notation in octet form. In binary notation the rightmost bit represents 1, the next 2, 4,8,16,32 and so on. This notation is used to denote iPv4 addresses in Internet protocol.

choice C. Perfect square trinomial is correct.

Step-by-step explanation:

We need to find the pattern which is represented by the polynomial $4x^2+12x+9$.

To find that pattern, we need to factor $4x^2+12x+9$

$4x^2+12x+9$

$=4x^2+6x+6x+9$

$=2x(2x+3)+3(2x+3)$

$=(2x+3)(2x+3)$

$=(2x+3)^2$

which is a perfect square.

Hence choice C. Perfect square trinomial is correct.

Option C - Perfect square trinomial.

Step-by-step explanation:

Given : Polynomial $4x^2+12x+9$

To find : What pattern is represented by the polynomial?

Solution :

First we make the polynomial in factor form,

Polynomial $4x^2+12x+9$

Since, it is not factor clearly so try to make the square.

Taking 4 common,

$=4(x^2+3x+\frac{9}{4})$

Identifying the x and y terms in the identity,$(x+y)^2=x^2+y^2+2xy$

$=4((x)^2+2\times x\times \frac{3}{2}+(\frac{3}{2})^2)$

Factor the perfect square trinomial,

$=4(x+\frac{3}{2})^2)$

Therefore, The pattern polynomial represent is perfect square trinomial.

So, Option C is correct.
