Giovanna recibe actualmente un ingreso anual de $42 000. normalmente, recibe
un aumento salarial de 2% al año debido al «costo de la vida».
1. determine cuál sería la ecuación que representa su situación actual.

Step-by-step explanation:

The salary per year is the combination of the $42000 per year (constant) plus the 2% rise per year. So the ecuation is:

Firt year

Second year

Generalizing:

For any item 5 pounds or greater, the following equation gives the price, p(w), of shipping the item between two locations as a function of the item's weight, w, in pounds. Then, the equation is for w>=5 (pounds).

The company does not use the following equation to determine shipping prices for items which are greater than 80 pounds. Then, the equation is used for
w<=80 (pounds)

The domain of p(w) is the values we can give to w, then
Domain of p(w) is 5<=w<=80
Domain of p(w) = [5, 80]

Domain of p(w) = [5, 80]
