Question

Help please ! I'll be your fan
Part 1: Create a scenario for an arithmetic sequence. For example, Jasmine practices the piano for ______ minutes on Monday. Every day she ___________ her practice time by _________. If she continues this pattern, how many minutes will she practice on the 7th day? Be sure to fill in the blanks with the words that will create an arithmetic sequence. Use your scenario to write the function for the 7th term in your sequence using sequence notation.

Answer 1

Part 2: Create a scenario for a geometric sequence. For example, Anthony goes to the gym for ______ minutes on Monday. Every day he _________his gym time by ____________. If he continues this pattern, how many minutes will he spend at the gym on the 5th day? Be sure to fill in the blanks with the words that will create a geometric sequence. Use your scenario to write the formula for the 5th term in your sequence, using sequence notation.

Part 3: Use your scenario from part 2 to write a question that will lead to using the geometric series formula. Use the formula to solve for Sn in your scenario.

Answer 3

I have a plan. Stop sucking!

Why not just fill in the blanks?

Jasmine practices the piano for __(A)____ minutes on Monday.
Every day she ____(B)_______ her practice time by ___(C)______.
If she continues this pattern, how many minutes will she practice on the 7th day.

(A) A nice non-negative number, please. 3, 6, 8, 16, 34, 16, 7 - Seriously, just pick one.

(B) Increases or Decreases? Be careful with "Decreases".

(C) Pick a nice non-negative number, please. 0, 5, 14, \(\sqrt{2}\) - Seriously, just pick one.

Answer 4

Lol, you dont understand, this is my second time taking algebra. Im perfect in every subject except algebra. Thanks for your help but it really did not help at all, I didnt understand anything you typed.

Answer 5

I do understand. You do not understand what I understand.

Pick a number. That's it. Look at the fingers on your hand. Decide how many of them to include. What do you get?

Answer 6

ok i pick 5 now what do i do

Answer 7

Arithmetic is a difference, so pick numbers that have a common difference that increase at a linear rate.

Answer 8

Perfect. We have filled in the first blank.

Jasmine practices the piano for FIVE minutes on Monday.
Every day she ____(B)_______ her practice time by ___(C)______. If she continues this pattern, how many minutes will she practice on the 7th day.

Now, type the word "increases:.

Answer 9

1 hour

Answer 10

That is NOT the word "increases". Just type the word. seriously. You can do it.

Answer 11

ok im not that stupid, she increases her practice by one hour, im trying to go alittle bit faster

Answer 12

Create a scenario for an arithmetic sequence. For example, Jasmine practices the piano for five minutes on Monday. Every day she increases her practice time by 10 minutes.

Answer 13

there, done, now what

Answer 14

Perfect. So you see, you DO understand more than you are admitting. Let's not hear that silliness again.

Okay, then here we are.

Jasmine practices the piano for FIVE minutes on Monday.
Every day she INCREASES her practice time by TEN MINUTES.

If she continues this pattern, how many minutes will she practice on the 7th day.

Monday is Day 1. We already established that she practiced five minutes on Day 1.
Tuesday is Day 2. Increase 5 minutes by 10 minutes. How many minutes did she practice on Tuesday?

Go!

Answer 15

15

Answer 16

@tkhunny

Answer 17

Perfect. How many minutes practiced on Wednesday, Day 3?

Answer 18

wed-35
thurs-45
fri-55

Answer 19

so wed-25 thurs-35 fri-45 ?

Answer 20

it increases by 10 doesnt it

Answer 21

How did we get to Wed = 35? Tue = 15 increased by 10 gives Wed = 25.

Give it another go and get all the way to Sunday.

(1) Mon = 5
(2) Tue = 15
(3) Wed =
(4) Thu =
(5) Fri =
(6) Sat =
(7) Sun =

It might help to get them all in front of you at the same time. It also might help if you just go one step at a time. So far, you have not liked what I have asked you to do. If you HAD done what I asked you to do, you would not have gotten a wrong answer. Since you became impatient and launched off, somewhere, you also became careless. One thing at a time. Start with patience. You may suck at high-speed math. Try slowing down and sucking less.

Answer 22

You forgot Tues

Answer 23

We volunteer, its not our responsibility to help you. You could be nicer because he probably has better stuff to do than help you.

Answer 24

Math is everywhere, so doing math is not a waste of time.

Answer 25

Nope. Your screen name suggests to me that you need "mentoring," as you call it. Since you have submitted yourself to this sort of assistance, maybe you should trust me. How did it go YOUR WAY the first time you took algebra?

I couldn't care MORE about you because I already care the maximum amount. You need to learn a little mathematics and I am quite capable of doing it. I've been in this effort since I was in the second grade (nealy 50 years!). I LOVE helping people. Over the years, I realized that I didn't love the students. Now I do. YOU are awesome and YOU can do it.

Did you fill in the chart all the way to Sunday?

Answer 26

You hurt him, smh *hugs tkhunny*

Answer 27

Worse. Decades of experience telling people what they need - even after they resist! :-) You want to learn mathematics, you are in touch with the right folks around here. A bunch of volunteers who have very little to gain except helping people! It's a pretty sweet deal.

Answer 28

*Pats himself on the back* You did good fiz, you did good.

Answer 29

How's that chart coming?

Answer 30

anyway, back to math, wed-25 thurs-35 fri-45 sat-55 sun-65, it increases by 10 each day doesnt it

Answer 31

they;re not negatives btw, just dashes

Answer 32

"...cause math is just not my thing" You simply HAVE to stop saying that. Math is everyones' thing. Like it or not, it is unavoidable.

That is super. You have just answered the first question. If she starts with 5 minutes and increases 10 minutes per day, day seven will get 65 minutes. That can also be thought of as six increases of 10 minutes each. 5 + 6(10) = 5 + 60 = 65 ----- Smae answer. Almost magic. :-)

It is very important that you have understood the idea that it "increases by 10 minutes each day". One day to the next, just another 10 minutes. How about the next day? Yup! Another 10 minutes. ALWAYS the same. This will arm you against liars.

When someone tells you,

It cost $10 two years ago
Then it cost $20 last year
Now, here it is this year at $30!!!!
Wow!!! The price is growing EXPONENTIALLY.

You can say,

No it's not, Silly! Don't you know anything?! The price is increasing in an arithmetic sequence. That's only LINEAR growth, not EXPONENTIAL growth.

Arithmetic Sequence (Linear Growth) changes by the same AMOUNT every time it changes.

Geometric Sequence (Exponential Growth) changes by the same PERCENTAGE every time it changes.

Now, go tackle Scenario #2. I have to go. You are doing excellent work. So much for that sucking you were talking about. :-)

Answer 33

@tkhunny yeah thanks, you lost me at linear and exponential and percentage and arithmetic and geometric ... and for the first scenario it says write a function for the 7th term in the sequence using sequence notation.... basically i dont even know how to write a function in the first place much less in a seqeunce notation

Answer 34

I also need help with the geometric sequence ...
Create a scenario for a geometric sequence. For example, Anthony goes to the gym for ______ minutes on Monday. Every day he _________his gym time by ____________. If he continues this pattern, how many minutes will he spend at the gym on the 5th day? Be sure to fill in the blanks with the words that will create a geometric sequence. Use your scenario to write the formula for the 5th term in your sequence, using sequence notation.
