Question

I NEED MATH HELP ASAP!!!!! MEDALS WILL BE GIVEN

Answer 1

Bill is able to save $35/week after working part-time and paying his expenses. These two formulas show his weekly savings:
f(1) = 35, f(n) = f(1) + f(n-1) for n > 1
f(n) = 35n
Which one of these formulas show the sequence written recursively and which shows it written explicitly? Justify your explanations.
Use the recursive formula to make a table of values for 1 ≤ n ≤ 5. Show your calculations. Explain what your table means.
Use any formula of your choice to find f(40). Explain why you chose that method and what your answer means. Show your calculations.
Given the sequence of numbers: 5, 6, 8, 11, 15, 20, 26, 33, 41,… Explain whether or not this sequence can be considered a function.

Answer 2

do you not understand the word problem or just the problem in general.

Answer 3

?

Answer 4

Oh! and I don't need a medal I simply enjoy helping people with math so only give me a medal if I can help relieve you of your math stress.

Answer 5

As a explanation for this problem for those of you who do not understand this:
This equation discusses an arithmetic sequences using the formulas included within the problem.

Answer 6

well the formula names I mean

Answer 7

so tell me how far how you gotten on the problem or do you simply do not understand this problem.

Answer 8

if you don't understand it what do you not understand about it be specific
please :)

Answer 9

I don't understand any of it really.
Sorry I didn't respond, I stepped away for a minute

Answer 10

alright I don't need a medal really but if I can explain this problem to you well
then will be willing to join a free open math community that gives rewards for doing math if you win their competitions.

Answer 11

Ok

Answer 12

Okay before we start I recommend watch a video on sec.

Answer 14

Ok

Answer 15

Well now I understand the first one. I just need help with the rest now. I appreciate your help.

Answer 16

use this rule
A. f(1) = 35, f(n) = f(1) + f(n-1) for n > 1

make a table
n | f(n)
-----------
1 | 35
2 | ?

you need to find f(2)
the rule says, for n>1 (and here n is 2, so we use it)
f(n) = f(1)+ f(n-1)
replace n with 2: f(2) = f(1) + f(2-1)
or
f(2) = f(1)+f(1)
from the table, we see f(1) is 35, so you get
f(2) = 35+35
f(2) = 70

Answer 17

Ok, thank you SOOOO much!!!

Answer 18

np :D

Answer 19

anytime u need help let me no

Answer 20

do you need more help?

Answer 21

ty guys for all the medals!

Answer 22

Yes, I need help with…
Use any formula of your choice to find f(40). Explain why you chose that method and what your answer means. Show your calculations.
and…
Given the sequence of numbers: 5, 6, 8, 11, 15, 20, 26, 33, 41,… Explain whether or not this sequence can be considered a function.

Answer 23

No prob ;)

Answer 24

plz post as a dif question :)

Answer 25

Ok

Answer 26

hmm this looks like a funtion because it goes up a strict amount each time.

Answer 27

function*
