Question

Jill has been watching the squirrels that live in her neighborhood. The number of squirrels changes each week.

n f(n)
1 8
2 12
3 18
4 27


Which function best shows the relationship between n and f(n)?

f(n) = 12(1.5)n

f(n) = 12(1.5)n-1

f(n) = 8(1.5)n

f(n) = 8(1.5)n-1

Answer 1

Which do you think it is

Answer 2

f(n) = f(1) • r^n-1

Answer 3

8*r^8-1

Answer 4

what is r

Answer 5

I'm guessing r is 1.5 and the answer is D

Answer 6

Nope, 8*1.5^4-1
8*1.5^3 = ?
It is D. Could you solve?

Answer 7

The exponent is time

Answer 8

Geddit? :D

Answer 9

yes thanks

Answer 10

@tHe_FiZiCx99 witch was the answer

Answer 11

What?

Answer 12

was it D

Answer 14

-_- Lol really? You're actually asking me for the answer to a problem I explained? Look at the explanation.. and get you're answer through that. @Lena772 was able to understand it, I'm not giving you the answers..

Answer 15

its D LOL

Answer 16

Then why'd you ask??

Answer 17

I'm guessing r is 1.5 and the answer is D
cause she said this and then you said

Nope, 8*1.5^4-1
8*1.5^3 = ?
It is D. Could you solve?

Answer 18

Yes, what didn't you get?

Answer 19

Nope, 8*1.5^4-1
8*1.5^3 = ?
It is D. Could you solve?
you said nope

Answer 20

What she got wrong is that she thought it was 8-1.. ^n-1 is to find which ever value you want.

Suppose you wanted to find for the 3rd week you would subtract 3-1 = 2

So, 8(1.5)^2

8*2.25 = 18

Answer 21

oh lol okay can you help me in one more

Answer 22

Which?

Answer 23

Zoe keeps track of the miles per gallon her car gets per week. She has accumulated the following data:

(1, 24), (2, 24.38), (3, 24.76), (4, 25.14)

What is the common difference or ratio?

The common difference is 0.38.

The common difference is 0.76.

The common ratio is 0.99.

The common ratio is 1.02.

Answer 24

This is arithmetic simply because their difference is .38

Subtract 24.76 - 24.38 = .38

Arithmetic is common difference. Geometric is common ratio.

Answer 25

so its A

Answer 26

Yes..

Answer 27

YAY LOL


last one

Answer 28

Melinda has shown that a function, f(x), increases by 4 for every unit in the domain. What does this prove?

The function f(x) is an arithmetic sequence.

The function f(x) is a geometric sequence.

The function f(x) is not a sequence.

This does not prove anything.

Answer 29

It increases by 4. is 4 geometric or arithmetic

Answer 30

arithmetic

Answer 31

Ok

Answer 32

so its A

Answer 33

Think of a graph.. have a better idea? Does that look geometric?
