A palindrome is a string whose reversal is identical to the string. How many bit strings of length n are palindromes?

alisha [4.7K]

Answer:

The number of palindromes is

$2^{\frac{n}{2} }$ when n is even and

$2^{\frac{n +1}{2} }$ when n is odd

Step-by-step explanation:

From the question we are told that

The length of the string is $n$

Generally palindrome is evaluated by considering the first part of a string

When the the length of the string is an even number then

it means that the first part of the string is $\frac{n}{2}$

Hence the number of bit strings of length n that are palindromes is evaluated as

$p(n_{even }) = 2^{\frac{n}{2} }$

But When the the length of the string is an odd number then

it means that the first part of the string is $\frac{n-1}{2}$

Hence the number of bit strings of length n that are palindromes is evaluated as

$p(n_{odd }) =2^{\frac{n -1}{2} +1 } = 2^{\frac{n +1}{2} }$

Generally each bit could be either 0 or 1

Hence the number of palindromes is

$2^{\frac{n}{2} }$ when n is even and

$2^{\frac{n +1}{2} }$ when n is odd

The figure shows a quarter circle and an equilateral triangle. What is thearea of the shaded part? Give your answer to 3 signifi

ad-work [718]

Explanation

The shaded area represents a segment. This can be solved with the formula below;

$\mleft(\frac{\theta}{360}\mright)\times\pi r^2-\frac{1}{2}r^2sin\theta$

Since the triangle is an equilateral triangle, it implies that the angle subtended at the centre is 60 degrees. Also, the given radius is 7 cm

$\begin{gathered} =7^2(\frac{60}{360}\times3.14-\frac{1}{2}\times\sin 60)^{}_{} \\ =49(\frac{3.14}{6}-\frac{\sqrt[]{3}}{4}) \\ =4.43\operatorname{cm}^2 \end{gathered}$

Answer:

$4..43\operatorname{cm}^2$

Between which two thousands is the number 36,219

Anastasy [175]

32,000 and 42,000. I know this because the question states "Two Thousands." 32,000 and 42,000 are both two thousands because 32 and 42 both end with 2's because of the "Two" in "Two Thousand."
