17. The function f(x) = - 5x ^ 2 + 17x + 21 models the predicted sales of a pen after price increases . Use the table showing actual and predicted sales to find the residuals for the model.

X. - Actual Sales. - Predicted sales - residuals
0 - 22 - 21
1 - 33 - 33
2 - 36 - 35
3 - 28 - 27

18. Function g also models the data in Question 17. For function g, the average distance of the residuals from the line y = 0 is 1.1 . Is f or g a better model for the data?

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?
