Ahh i see thanks for the trick!

im blind

sos, my fualt

ive changed my answer and ignore the other post

You are right, 12% is indeed 0.12.

However for the percentage increase you add this to 1 to make 1.12

12%=0.12 not 1.2

So...

x=initial

x*1.12=26.88

Therefore x=26.88

                     ........

                    1.12

Answer:£24.00

LOL!!!!

The "formulas" for the first two are similar.......just the times compounded per year are different

A = P (1 + r / n)^(n *t)     where P is the principal, r is the interest rate, n is the number of compoundings per year and t is the number of years

A)  Yearly

5000(1 + .085/ 1)^(1 * 6 )  ≈  $8157.34

B) Monthly

5000(1 +.085/12)^(12* 6)   ≈ $ 8311.50

C)  Continuously ......   use  A =    Pe^(rt)      

5000e^(.085 * 6)  ≈  $8326.46

We are using   log(a * b)   = log a+ log b    ......so.......

log (4m^3n^7)  =  

log 4 + log m^3  + log n^7

Now we can use    log a^b    =  b log a

log 4 + 3 log m  + 7 log n

---   First Take out a 3, since 3 can go into 3 and 6

3x²      

3x

----      Then, since there is an x on top and an x on the bottom you can get rid of one from each the top and bottom

x²

3/x    Would then be the answer.

Are you trying to find the diameter or what is it you are trying to find?

(2/3)^2 = 0.4444444444444444

c=62.83cm

Well....it could be lots of things.....but....let's try this one.........

Let's assume that this is the bottom half of a sideways parabola opening to the right

Let's call the vertex  (h,k)  =  (5 ,6)     and we know that point  (9, -2)  is on the graph.......so........we have this form :

(x - 5) = a(y - 6)^2      now......substitute 9 for x and -2 for y   and solve for a......and we have

(9 -5)  = a(-2 - 6)^2

4  = a(64)   divide both sides by 64

a = 4/64   = 1/16

So........our full equation is

(x - 5)  = (1/16)(y - 6)^2     but we only want the bottom part of the graph....so....    

Multiply both sides by 16

16(x - 5)  = (y - 6)^2         take the pos/neg square roots of both sides

± 4 √ (x - 5)  = y  - 6

Since we want the bottom part, we will take the negative root

- 4 √ (x - 5)  = y  - 6     add 6 to both sides

-4 √ (x - 5) + 6  = y    and we can write this as :

y = -4 √ (x - 5) + 6 

Here's the graph : https://www.desmos.com/calculator/tpovquifna

1.A snail has a foot but no legs...maybe

2.Nothing

3.Rain

4.A candle

5.Mary is the fifth daughter

6.A pant pocket could have a hole in it.

7.No stairs. One story house.

8.The person operating on the son was the Mother.

9.A umbrella

I got the same result as Alan did.....as a check......

y - p^2x   .......     let x = 5p - 5/p  .....    and let y = -x      ....   and we have....   

[5/p - 5p] - p^2 [ 5p - 5/p]  =

5/p - 5p - 5p^3 + 5p  =

5/p - 5p^3       and this  =  the right side

So.......the solution should be :

(x , y)   =   ( 5p - 5/p ,  5/p - 5p )

Arctan(0.4) ≈ 21.8 degrees

The standard deviation is the square root of the variance.

Replace y by -x

-x - p^2*x = 5/p - 5p^3

-x*(1 + p^2) = (5/p)*(1 - p^4)

-x*(1 + p^2) = (5/p)*(1 + p^2)*(1 - p^2)

-x = (5/p)*(1 - p^2)

x = -5/p + 5p

Hence y = 5/p - 5p

Hmm, doesn't match your desired solution!

a hill has a foot but no legs

?

?

a mountain is tall when it is young and short when it is old

mary is the fifth daughters name

the pocket still has air in it

there are no stairs in a one-story house

the son has two dads

69.

write as 21/8 * 11/4

mulptiply 21/8 by 125 to get 2625/1000

multiply 11/4 by 250 to get   2750/1000

2625/1000 becomes 2.625

2750/1000 becomes 2.75

multiply to get 2.625*2.75=7.21875

(i know there is an easier way but i cant think of it off the top of my head)
