Answer 3

O @Unavailabilityy

Answer 4

Answer 5

great i can't wait. quickly please i am Timed

Answer 6

aww ok after i get her

Answer 7

nvm she can

Answer 8

@acxbox22 you have a high rank am sure you can do something here./..

Answer 9

I will help

Answer 10

Yea well I was just refreshing my knowledge on average rate of change.

Answer 11

What do you know to begin with?

Answer 12

@Kevin can help he helped my sister just a couple min ago and she got her thing right!

Answer 13

a = 8

an = a x r^(n-1)
an = 8 x 1/2(n-1)

average rate of change
a3 - a1/ (3 - 1) =
8 - 2 / 2 =
6 / 2 =
3

So the answer is the third poin

Answer 14

acxbox can you list your answer i can't explain now really am doing other problems.. Thank you

Answer 15

Kevin you sure that the answer is C?

Answer 16

Since you are given choices, you can test the equations with the graph.

Answer 17

Tq @GIitter :D
Thx for mentioning me ^^

Answer 18

the answer is not c

Answer 19

Uh, I;m terrible at algebra ;-;

Answer 20

the answer is E

Answer 21

acxbox i will give you all kinds of awards just list you explanation and answer.

Answer 22

I'm sorry
I calculate it wrong

Answer 23

@Kevin please dont give direct answers

Answer 24

an = a x r^(n-1)
an = 8 x 1/2(n-1)

average rate of change
a3 - a1/ (3 - 1) =
2 - 8 / 2 =
-6 / 2 =

-3 So the answer is the A

Answer 25

^

Answer 26

WHAT @acxbox22 SAID

Answer 27

Sorry caps lol

Answer 28

Keving you sure this time? it's worth 12% of the general test

Answer 29

So testing the equations,

we can see that when we substitute in the values of n or x in the equations, only the first and third equations make sense

when n is equal to 1, 8(1/2)^(1-1)

= 8(1/2)^0= 8

and looking at the graph

when n=1, y is equal to 8 meaning our equation is correct.

Answer 30

who do you trust @Will.H?

Answer 31

yup, I'm sure

Answer 32

wbu @acxbox22

Answer 33

A is the correct answer as @Kevin mentioned but it is important for the person to understand how we got there.

Answer 37

Kevin can i reach to you for other questions?

Answer 38

you may give it to anyone you wish, we are all friends here

Answer 39

my pleasure :)

Answer 40

So continuing on, we are left with answer choices A and C.

The next part is average rate of change.
We need the average rate of change between n=1 and n=3

so we use the formula \[(f/b-f/a)/b-a\]

when n=1, the function is 8 and when n=3 the function is 2

so we have \[(8-2)/(1-3)\]

which is equal to -3 or the average rate of change for the function.

Answer 41

Brilliant! Thanks a lot for yall

Answer 42

np ;)

Answer 43

u're welcome :)

Answer 44

Good job guys!

Answer 45

If I could I would go and give you both a medal but I gave to Will for asking the question and being patent for the answer :).
