After a weather balloon is launched the following data is sent back to the meteorological center. The column marked time,
Approximately how fast (in ft/sec) is the balloon rising at
seconds? Since we cannot find the derivative (IROC), calculate the average rate of change.
For:
You could use Hana’s method:
or Anah’s method:
or Hanah’s method:Approximately how fast is the temperature changing (in °F/ft) at
feet? Use Hana, Anah, or Hanah's method to approximate the rate of change for
at . Approximately how fast is the temperature changing (in °F/sec) at
seconds? Use Hana, Anah, or Hanah's method to approximate the rate of change for
at . Why would you expect the product of the answers to (a) and (b) to equal answer (c)?
