Question 1 5 out of 5 points True or false? log(n) is big-O of n, but n is not big-O of log(n). Selected Answer: Tru e Answers: Tru e False Response Feedback: Logarithms grow slower than linear functions. Question 2 5 out of 5 points True or false? Any polynomial function p(n) is big-O of any increasing exponential function (a is a number greater than 1). Selected Answer: Tru e Answers: Tru e False Response Feedback: Exponential functions (with base > 1) grow faster than all polynomial functions.

Answer: Correct Answer: 4 Answer range +/- 0 (4.0 - 4.0) Question 4 5 out of 5 points True or false? Any two polynomial functions are of the same order. Selected Answer: Fals e Answers: True Fals e Response Feedback: Two polynomials are of the same order if and only if they have the same degree. Question 5 0 out of 5 points True or false? To verify that 101 is prime, we merely need to test divide it by 2, 3, 5, 7. The fact that 101 is not divisible by those numbers guarantees that it is prime. Selected Answer: Fals e Answers: True False Response Feedback: To test n for primality through trial division, it is sufficient to check all primes no greater than the square root of n. Since 101 is strictly between 100 and 121, the square root of 101 is strictly between 10 and 11. The primes that are less than the square root of 101 are therefore 2, 3, 5, 7. Question 6 7 out of 7 points Enter the decimal representation of the hexadecimal number FF. Selected Answer: 255 Correct Answer: 255
Answer range +/- 0 (255.0 - 255.0) Response Feedback: Well done! Question 7 7 out of 7 points Enter the octal representation of the decimal number 13.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
