How would you solve the equation 5 t^2 + 3 t + 2 = 4 t - 7 using DERIVE?
How would you enter the data points (0, 100), (10, 70), (20, 50) into DERIVE?
How would you then fir a quadratic function to this data set?
The following data were taken for a series of pendulums:
| pendulum length in feet | number of cycles counted in 60 seconds |
| 1 | 55 |
| 2 | 40 |
| 3 | 33 |
| 4 | 29 |
| 5 | 23 |
Plot this data, with y being the number of cycles and x being the pendulum length:
If this function is modeled by a power function of the form y = a x^p, then do you think p is positive or negative, and why?
