Answer 1

The table below represents the volume of a liquid sample as a function of its temperature:
Temp (C) Volume (ml)
x f(x)
11 95
16 100
21 105
26 110
The average rate of change of f(x) between x=11 to x=21 is _____ ml per C ((degrees)) and represents the rate of change of volume per degree rise in temperature
I keep getting 5 but im not sure please help :(

Answer 2

@ganeshie8

Answer 3

do you know what they mean by rate of change ???

Answer 4

no

Answer 5

Answer 8

which formula you used

Answer 9

y2-y1/x2-x1

Answer 10

yes so
now solve

Answer 12

I got 1 so is 1 the answer?

Answer 13

yea

Answer 14

yes that is your answer

Answer 15

but remember formula is \[m = y _{2} - y _{1} / x _{2} - x _{1}\]
so always you have to plug y2 value first
