Question

The table below represents the atmospheric temperature at a location as a function of the altitude:
- Altitude (in thousand feet) x : 15, 20, 25, 30
-Temperature (in °C) f (x) : 4, -6, -16, -26
The average rate of change of the function between x = 15 to x = 25 is______ degrees Celsius per thousand feet and represents the rate of change of temperature per thousand feet.

Answer 1

Answer:

2°C

Step-by-step explanation:

change in altitude = 25000-15000 =10000 feet

change in temperature=4-(-16) =20 degree Celsius

therefore change in temperature per thousand feets= 20/10 = 2 degree Celsius
