**RES/342**

a scatter plot of the number of women in the workforce versus the number of Christmas trees sold in the United States for each year between 1930 and the present, you would find a very strong correlation. Does one cause the other? Why do you think this correlation might be true?

**RES/342**

A political action committee decided to poll its membership to determine if they were in favor of a certain potential law, similar to gun control. The results that came back were 125 in favor of the law, and 120 against. Given that the crew at the center would use the fact ...

f(t)=1/3(t+145)^2 - 67 Find the inverse? is it t=1/3(f+145)^2-67

**Calculus**

For a given take-off weight, the take-off distance increases if the air temperature increases. For a specific example, if a KC-135 weighs 200,000 lbs, the take-off distance is modeled by f(t)=1/3(t+145)^2 - 67. If D = f(t) , where D is the take-off distance as a function of t...
