I thought it was EPs comment but no - it was The Ninja's answer.   LOL

Sorry guys.

i know, just trollin

The answers are identical EP :/

A little error EP.

It is not  0.1632  it is  0.165    :)

36.....

ha.....ha...ha..ha.ha.ha.HAHAHAHAHAHAH.no.

f(x) = ax^2+bx+c

x = (-b+sqrt(b^2-4ac))/2a

x = (-b-sqrt(b^2-4ac))/2a

if that is what u mean then there

Lol thanks!

For Guest's question. It took 3 hours but i had nothing else to do so yeah whatever. Probably wrong

18072.3 + 18997.6/(x + 1) + 18819.8/(x + 1)^2 + 18638.5/(x + 1)^3 + 18453.5/(x + 1)^4 + 18264.8/(x + 1)^5

Answer: x = -2.01045

x = -1.51032 - 0.865886 i

x = -1.51032 + 0.865886 i

x = -0.510056 - 0.866066 i

x = -0.510056 + 0.866066 i

Sorry CPhill but that is incorrect. The correct answer is 5 7/20

Linda owes $3,861 on a credit card with a 22.3% interest rate compounded monthly. What is the monthly payment she should make in order to pay off this debt in 2 years, assuming she does not charge any more purchases with the card?

That interest rate is a nominal annual rate.

The effective rate is really    22.3/12 = 1.8583 repeater %  per month

So you have

rate =i = 0.0185833333 repeater

number of time intervals  = n=24

PV=$3861

Payments made at the end of each period so it is the present value of an ordinary annuity.

\(3861=C*\frac{1-1.018583333333^{-24}}{0.018583333333}\\ 3861\div \frac{1-1.018583333333^{-24}}{0.018583333333}=C\\\)

3861/((1-1.018583333333^-24)/0.018583333333) = 200.87401691850546370528435959

Monthly payment (at end of month) = $200.87

5.35   = 

5 +  35 / 100  =

5 +  7 / 20 

Why would you assume that guest.  You have explained nothing, so what was the point in answering?

Hi Guest,

You have put your question on the end of an ancient post (april 2015)

I can see thast CPhill is answering it for you but often it would go un-noticed.

You need to post a new question on a new thread and then it is usually answered quite quickly :)

A 25 foot ladder is placed against a building. The bottom of the ladder is 7 feet from the building. If the top of the ladder slips down 4 feet, how many feet will the bottom slide out?

In the first instance, the ladder's height up the wall =

√ [25^2 −  7^2]  = √ [625 −  49]  = √ 576   =  24 ft

If it slips down 4 ft....the bottom  will be

√ [25^2 −  20^2]  = √ [625 −  400]  = √ 225   =  15 ft     from the wall

So....he bottom slides out  15 −  7   = 8 ft

A 25 foot ladder is placed against a building. The bottom of the ladder is 7 feet from the building. If the top of the ladder slips down 4 feet, how many feet will the bottom slide out?

You start with 100% 

you loose 5%

You are left with    (100-5)% = 95%

so if you start with $250 and you loose 5% you end up with

95% of 250 = 0.95*250 = $237.50

Do you have a more precise queestion?    That is a bit vague to me.....

Thats really clever with those brackets :)

Very nice, Melody.....!!!!

solve for 2017 using these numbers only once: 100, 50, 8, 2, 1, 1

I'll give you my logic first and follow it with the answer.

8*50=400

8*2*100=1600

8*2=16

400+1600+16   +1 = 2017

so

8(50+200+2)  +1 =  2017

8[ 50 +2(100+1) ]+1 = 2017

----------------------------

so we have

100+1=101

2*101=202

202+50=252

252*8=2016

2016+1=2017

I am going to assume that you already know and have the formula to calculate a loan payment! Based on that, Linda's monthly payment on her Credit Card over a 2-year, or 24-month period @ 22.3% will be =$200.87.

And NinjaAnswer is ONLY 12 years old!!.

Well....three "great minds"  couldn't possibly be wrong.......LOL!!!!!

Yep I agree with Ninja and CPhill  :)
