EJERCICIO 1.

LA COMPUTADORA EMPIEZA A HACER RUIDOS RAROS EN EL CPU, PERO NO LE TOMAS IMPORTANCIA; A LA SEMANA SE APAGA Y REINICIA SOLA MIENTRAS SE ESTA USANDO.

ACCION: DECIDES REVISAR LA COMPUTADORA Y TE DAS CUENTA QUE TIENE CABLES QUEMADOS, POR LO CUAL LA REPARAS DE INMEDIATO.

MANTENIMIENTO PREVENTIVO:

Cprogram to find //perimeter of rectangle printf(" \n perimeter of rectangle \n"); printf(""); printf("\n enter width and length of the rectangle : "); scanf("%f%f", & width,& length); perimeter = 2 * (width + length); printf("perimeter of rectangle is: %.3f", perimeter);  

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 !

The answer is: a join on clause.
