Assume that f is a polynomial and x=10 is a critical number for f. If
f′′(10)=−√2,
what do we conclude from the Second Derivative Test?

A) f has a local maximum at x=10
B) f has a local minimum at x=10
C) f has inflection point at x=10
D) f is concave up for x>10
E) f is concave down for x>10

For a school newspaper article, cienna conducted a survey to find out students’ favorite subjects. she polled all the students in mrs. lopez’s advanced dance class. why is her data likely to be skewed? honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented. cienna should have interviewed all the students in the school to get more accurate data. honors dance students are more likely to enjoy dance than students in the general population, so dance will be underrepresented. cienna should have interviewed only every other student in the class to avoid having too many people.

The ratio pv to nrt is plotted against pressure for ch4 at 0°c and 200°c. why does the curve for 0°c drop below the horizontal line for an ideal gas whereas the curve for 200°c does not?

What is the quadric regression equation that fits these data
