just rearranging. Explanation is not needed.
Use modular arithmetic to prove that 3|(221 – 1) for an integer n > 0. Hence, 3|(221 – 1) for n > 0. To show that 3|(221 – 1), we can show that (221 – 1) = 0 (mod 3). We have: (221 – 1) = (4” – 1) (mod 3) Then, (22n – 1) = (1 - 1) = 0 (mod 3) Since 4 = 1 (mod 3),...

a). Provide a DFA M such that L(M) = D, and provide an English
explanation of how it works (that is, what each state
represents):
b). Prove (by induction on the length of the
input string) that your DFA accepts the correct inputs (and only
the correct inputs). Hint : your explanation in part a) should
provide the precise statements that you need to show by induction.
For example, you could show by induction on |w| that

6. Suppose we want an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 10. a) How many parity bits are necessary? b) Assuming we are using the Hamming algorithm presented in this chapter to design our error-correcting code, find the code word to represent the 10-bit information word: 1001100110

Please solve all parts of the question
6. (10 points 5+5) We want to prove by contradiction that, for all integers k not divisible by p, if p is prime then no two different numbers in the set Ak(k,2k, 3k.. 1)k) are congruent mod p. (a) Clearly state the assumption to begin the proof by contradiction. (b) Complete the proof by making two observations regarding this assumption that immediately lead to a contradiction

This assignment asks you to prove the following Proposition 1 Let {n} and {n} are two sequences of real numbers and L is a number such that (1.a) un → 0, and (1.b) V EN, -L Swn. We illustrate the proposition. To begin, one can check from the definition that 1/n 0. This fact, plus the arithinetic rules of convergence, generate a large family of sequences known to converge to 0. For example, 11n +7 1 11 +7 3n2 -...

Please do exercise 129:
Exercise 128: Define r:N + N by r(n) = next(next(n)). Let f:N → N be the unique function that satisfies f(0) = 2 and f(next(n)) =r(f(n)) for all n E N. 102 1. Prove that f(3) = 8. 2. Prove that 2 <f(n) for all n E N. Exercise 129: Define r and f as in Exercise 128. Assume that x + y. Define r' = {(x,y),(y,x)}. Let g:N + {x,y} be the unique function that...

Approximating With Simpson's Rule 6) Now we want to use Simpson's Rule to find the volume of the machine part. Remember that Simp- son's Rule approximates integrals, not just areas. Since we don't just want the area under the radius function, we can't just apply Simpson's Rule to the radius function. If we let f(x) be the radius of the machine part at the point x, write down the integral that gives the volume of the machine part (with an...
