Answer:

The first '5' terms of the given sequence

[tex]\frac{7}{2} , 4 ,\frac{9}{2} ,5,\frac{11}{2}[/tex]

Step-by-step explanation:

Explanation:-

Given that the [tex]n^{th}[/tex]    aₙ =     [tex]\frac{N}{2} + 3[/tex]

first term

Put n=1  ⇒     [tex]\frac{1}{2} + 3 = \frac{7}{2}[/tex]

second term

Put n=2 ⇒   [tex]\frac{2}{2} + 3 = 1+3=4[/tex]

Third term

Put n=3 ⇒   [tex]\frac{3}{2} + 3 = \frac{3+6}{2}=\frac{9}{2}[/tex]

Fourth term

Put n=4 ⇒  [tex]\frac{4}{2} + 3 = 2+3 =5[/tex]

Fifth term

Put n=5 ⇒ [tex]\frac{5}{2} + 3 = \frac{5+6}{2}=\frac{11}{2}[/tex]

The first '5' terms of the given sequence

[tex]\frac{7}{2} , 4 ,\frac{9}{2} ,5,\frac{11}{2}[/tex]

Step-by-step explanation:

9=3^2 and 10^4=(10^2)2

The number 9 x 10⁴ is a square number. which the correct answer would be an option (B).

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

As per option (A),

4 x 10⁵

This number is not a square number.

As per option (B),

9 x 10⁴  = (3² x 10²)²

This number is a square number.

As per option (C),

4 x 10³

This number is not a square number.

As per option (D),

9 x 10³

This number is not a square number.

Thus, the number 9 x 10⁴ is a square number.

Hence, the correct answer would be option (B).

Answer:

AB ≈ 8.86 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{13.5}[/tex] ( multiply both sides by 13.5 )

13.5 × sin41° = AB , then

AB ≈ 8,86 cm ( to 3 significant figures )

Answer:

8.87

Step-by-step explanation:

use the sin law for right triagles sin(θ)= opposite/hypotenuse so

sin(41)=(AB)/13.5

13.5×sin(41)=AB

8.87=AB

 [tex](-4)^{2} = \frac{1}{16}[/tex]

Step-by-step explanation:

Explanation:-

Given    (-4)⁻²

we will apply (a)⁻ⁿ = [tex]\frac{1}{a^{n} }[/tex]

       (-4)⁻² =  [tex]\frac{1}{(-4)^{2} }[/tex]

                [tex]= \frac{1}{(-1)^{2} (4)^{2} }[/tex]

               [tex]= \frac{1}{16}[/tex]

 [tex](-4)^{2} = \frac{1}{16}[/tex]
