After t seconds the displacement, s(t), of a particle moving rightwards along the x-axis is given (in feet) by
s(t) = 4t^2-5t+3
By determining the average velocity
successively over the time intervals
[1, 1.1], [1, 1.01],
what is a plausible estimate for the instantaneous velocity, v(1), of
the particle at time t = 1.
ANSWER CHOICES:
1. v(1) = 3 ft/sec
2. v(1) = 1 ft/sec
3. v(1) = 4 ft/sec
4. v(1) = 5 ft/sec
5. v(1) = 2 ft/sec

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?
