In 1845, many mill girls earned 40 cents a day for working 12 hours. In 2001, the minimum, or lowest allowed, wage in the United States was $5.15 hour. About how much did the mill girls earn an hour?

  3 1/3 cents per hour

Step-by-step explanation:

The 1845 earnings per hour were ...

  (40 cents)/(12 hours) = (10/3) cents/hour = 3 1/3 cents/hour

Comment on the rate of increase

That's an average rate of increase of wages of about 3.28% per year, substantially higher than the 2.04% average rate of inflation over that period. The mill girls' wage is roughly equivalent to $0.78 per hour in 2001 dollars.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
