again :D

Thanks Solveit, 

So that means that the kite is approx 184.7 feet above the ground !

Don't forget to put the units in your final answer     

pi have infinitly number of digits

You could use an iterative numerical method.  Suppose you want to find the square root of the number m, say.  

Makle an initial guess x₀ (just set it to m/4 or something like it) then for a number of iterations i, use

x_i = (x_i-1 + m/x_i-1)/2   until x_i is the same as x_i-1.

For example, suppose you want to find the square root of 3:

​

If it is 40° then:  x = 12*tan(40°) = 12*0.8391 = 10.0692

I do not thnk 7up has a specific role in Camelot does he Rosala?

I know the 2 of you are good friends but he is not here very often ://

Density is weight per volume but you need units :/

With the first option....the total amount that you have earned =

1000 (30)(31)/2  = $465,000

With the second option.....the amount you have earned =

.01[1 - 2^30] / [1 - 2]  = $10,737,418.23   ......!!!!

Obviously.....the second one is better

We need to solve this equation for n to find out when the second is better than the first

1000(n)(n + 1)  / 2   <  .01[1 - 2^n] / [ 1 - 2]

This is best solved using an online app....WolframAlpha shows the answer to be about 24.98 days......so .....option 2 is better in about 25 days

LOL ZEGROES! That is what reasonning is called!

Because Melody. He's a b***h... a MATHBITCH...What?

Thanks, guys. I should.

Mathsbitch, why are you rude to people?  

Do you have some huge chip on your shoulder the size of Mt Everest?

That is what I think that your problems is.....

I have seen you give some good answers.  

You could fit in here nicely if you wanted to and you could make some real friends.  

Why are you so intent on alientating everyone?

Just ignore him DS. He obviousy doesn't know the value of art...or respect

It is mine, not yours, you dumb c**p!

That is very rude! I keep them as a collection, you RETARDED C**P!

Standard normal distribution

P ( x < 0,31 ) = 0.62172

P(-2.96 < x < 0.25 ) = 0.59871 - ( 1 - 0.99846 ) = 0.59871 - 0.00154 = 0.59717 = 0.597(17)

Solveit,

Your answer is very good but you would have been better off to stick to exact values.

AD =sqrt (10)

AB = 2*sqrt(10)

so     AB/AD = 2

I am sure that this would be true for the other ratios that you looked at as well.

So the triangles are similar AND the dimensions of the bigger one are exactly twice that of the smaller one  :))

Thanks, all! I am posting another one!

Nice, DS !!!!!

1. Ball up: n=11

\(\small{\begin{array}{lrcll} 1. \text{ Ball up }: \qquad && s_{10} = 40\cdot ( \frac{1-0.7^{10}}{1-0.7} ) &=& 129.5669967\ m\\ 2.\text{ Ball down }: \qquad &+& s_{10} = 40 \cdot ( \frac{1-0.7^{10}}{1-0.7} ) &=& 129.5669967\ m\\ 3.\text{}: \qquad &-& &&40\ m \\ \end{array}}\)

= 2 * 129.5669967 - 40  m

= 219.1339934 m

25/y = 10     multiply both sides by y, divide both sides by 10

25/10  =  y   =  5/2   =  2.5
