Question

The table below represents the atmospheric temperature at a location as a function of the altitude.
Altitude
(in thousand feet)
x
Temperature
(in °C)
f (x)
15
4
20
-6
25
-16
30
-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. (3 points)

Answer 1

best time to do hw is right now because only pros at this help you since everyone sleeping

Answer 2

-12?

Answer 3

x= 15 y = 4
x = 25 y = -16

Basically, what is the different of 4 and -16

Answer 4

difference

Answer 5

-12...

Answer 6

What is 4 - -16

Answer 7

oops

Answer 8

20

Answer 9

So when the graph went up 10k feet in the atmosphere, the temperature went down 20 degrees

This means that every 10k increase in altitude, there is drop of 20 degrees Celsius

Answer 10

Now the question is asking per thousand feet, not per 10k feet

Answer 11

So

\[\frac{ 20degreesC }{ 10,000feet }\]

Simplify the fraction down to 1000feet

Divide 20 degrees by 10, divide 10000 feet by 10

\[\frac{ 2degreesC }{ 1000feet }\]

The temperature drops 2 degrees Celsius every 1000 feet

Answer 12

ooo this was a fun problem

Answer 13

i understand now

Answer 14

thanks!
