Each of the following problems describes an algorithm implemented on a computer satisfying the axioms (13.5) and (13.7). for each one, state whether the algorithm is backwad stable, stable but not backward stable, or unstable, and prove it or at least give a reasonably convincing argument. be sure to follow the definitions as given in the text. (a) data: x e c. solution: 22, computed as x q x. (b) data: x e c. solution: x2, computed as x @ x. (c) data: x e c \{o). solution: 1,computed as x @x. (a machine satisfying (13.6) will give exactly the right answer, but our definitions are based on the weaker condition (13. (d) data: x e c. solution: 0,computed as x x. (again, a real machine may do better than our definitions based on (13.

Answer (c) worn brakes pads;

It’s definitely true

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !
