It will travel 3.5 meters.

Sorry, incorrect

:) 

What is a?

What is r?

What is the formula. 

Plug a and r into the formula and put it equal to 7

Then solve.

The x^3 term will be    ax^2*3x  +  -5x*bx^2 = (3a-5b)x^3

so    3a-5b = 20

Now find x^2 term and then solve simultaneously.  

I know that but I'm confused on how to solve it...

This is the infinite sum of a GP and it equals 7

Does that help?

Thanks very much! I will use your hints.

Boxes

\( \boxed{\phantom{X}}>\boxed{\phantom{X}}>\boxed{\phantom{X}}<\boxed{\phantom{X}}<\boxed{\phantom{X}}\)

LaTex for the boxes:

\boxed{\phantom{X}}>\boxed{\phantom{X}}>\boxed{\phantom{X}}<\boxed{\phantom{X}}<\boxed{\phantom{X}}

The middle one must be the smallers so the middle one is 1

Now counting.

54123

53124

52134

43125

42135

32145

so I get 6 ways

LaTex for the boxes:

\boxed{\phantom{X}}>\boxed{\phantom{X}}>\boxed{\phantom{X}}<\boxed{\phantom{X}}<\boxed{\phantom{X}}

That is interesting. I shall try and remember it. 

Hi asinus!
I think we got different answers as:

\(sin(\beta) \neq \dfrac{tan(\beta)}{\sqrt{1-tan^2(\beta)}}\)

But I think you meant: \(sin(\beta)=\dfrac{tan(\beta)}{\sqrt{1+tan^2(\beta)}}\) which is an identity.

Also, \(sin(\theta) \neq \sqrt{1-cos^2(\theta)}\) but rather, \(sin(\theta)=\pm \sqrt{1-cos^2(\theta)}\), and we choose +ve or -ve sign depending on the quadrant.

Since theta is in the third quadrant, then sin(theta) should be negative, so we must choose the -ve, and not the positive, as then theta will be in the first quadrant or second, but we are given it is in the third.

Thanks Asinus,

Also asked and answered here

I see you have asked the same question again.

Please do not do that.

You can make another post just putting a link back to the original question and asking people to answer on the original if you want to.

Guest has put a lot of work into this answers (I have not looked at it myself but at a glance it looks impressive, thanks guest.

Don't you understand the answer given?  You were asked for an exact value, not an approximation. 

You didn't thank guest for his/her efforts either.  Didn't even give him a point.

I know you are a new member so some of these oversites could just be you not understanding how it works. I am sorry if I have sounded to harsh.

Please simplify guests answer and tell us what you get. I want to see if you can do that properly.

For you and others:

You have another answer from asinus here:

The smallest possibe sum is 66.

The distance is 8.5 miles.

The probability is 7/33.

That answer is wrong.

There are 486,450 ways.

The solutions are 5 + sqrt(2) and 5 - sqrt(2).
