125=5^3

25=5^2

5^2+5^3= 5^5 or 5x5x5x5x5

sqrt(5^5)= 5^2 sqrt(5)

4/8=1/2

1/2=z/72

(72)(1/2)=(z/72)(72)

36=z

4x4x4=64

To do fraactions, press divide. 

For example: If you want 2/3, you would do 2 divided by 3, and the rest of your equation. 

This cannot be simplified or factorised.

The graph.

It can display up to 20 or so digits. And it can handle "factorials" up to 199!=~10^372.

Let us find the square root of eg 266,256...split this into pairs 26 62 56

               ..   )26'62'56( *5 1 6     The sq rt of 26 is *5+1    We put 25 under the 26 subtract leaving 1 ..  .."..................25.               Bring down the 62 = 162

".               10) 162.         now double the answer *5=10 we now need a number which when put after the 10 and multiplied by the same number in this case 1= 101x1 subtract from 162 = 61 bring down the 56 

...............101)..101.         

                102)   61.             so we now have 6156 we double the result so far (*51)=102 apply the same as before adding a number which when put next to the 101 and multiplied by the same number which is nearest to 5156 in this case it is 6,,,,we have 1026x6=6156. So the answer to the square root of 266256 = 516

When using this method it is important to split the original number in pairs STARTING from the decimal point ie if the number is eg  23456.000the split would be  2'34'56 so the first calculation would be the nearest square root of 2 = *1 subtract from the 2=1and the next calculation would be double the *1=2 bring down the 34 =134..the number added to the 2 and multiplied using the same number which is 5 so we have 25x5=125 subtract from 134 =9 .bring down 56 =956 double answer so far (*15)=30 find the number when added and multiplied is nearest to 956 which is 3 ie 303 x3=909 leaving 47 bring down 00 giving 4700 ..double *153=306 the next number is 1= 3061 deduct from 4700 etc etc

All of this seems complicated ,but try it .

If Merin worked for 48 hours, 40 of those hours are paid as regular hours and 8 are paid as overtime hours.

Call her regular rate 'x'.

Then, since she makes 1.5 times her regular rate for all overtime hours, her overtime rate is '1.5x'.

The amount of money earned is found by multiplying the number of hours times the rate.

     --->     Regular amount =  40·x               --->     Overtime amount  =  8·1.5x

Total amount made for the week is found by adding the regular amount to the overtime amount:

    (40·x) + (8·1.5x)  =  650.00

--->     40x + 12x  =  650.00

--->               52x  =  650.00

--->                   x  =  $12.50     <---      her regular rate 

How do I solve this y=x-x^2?

I need to know the turning points. Idk if it is the right word but i hope you understand me!

This is a parabola, I know that because of the x^2 term

This is a concave down.  I know that because of the - sign in front of the x^2 term.

\(y=x-x^2\\ y=-x^2+x\\ y=-x(x-1)\\\)

The roots are  x=0  and x=1

the axis of symmetry  is x= 0.5

when x=0.5

y= -0.5 * (0.5-1)

y= -0.5 * -0.5

y= 0.25

So the tuning point is a maximum and it is at     (0.5, 0.25)

1 1/2 x 6 2/3

this is the only way :)

(1+1/2) x (6+ 2/3) = 10

This is my interpretation.

3x+3(x-2)= 3(x+6)

3*x+3*(x-2)= 3(x+6)

 x=8

\(3x+3(x-2)= 3(x+6)\\ 3x+3x-6= 3x+18\\ 6x-6= 3x+18\\ 3x-6= 18\\ 3x= 24\\ x=8\)

So yes your answer is correct.

Maybe next time you can set your question out better :)

Three.

Enter  asin(0.934)  in the calculator on the home page here.

Oh yea, I forgot about that.  Thanks Alan :)

Oh and that is if rotations are counted as the same !

Max that is not correct.

Plus you need to state the seating arrangment.

If they were sitting in a circle then the answer would be

14! - 2*13!  = 

14!-2*13! = 74 724 249 600

Come to think of it, modulus can mean the same as modulo!

.

It has several meanings in mathematics.  When used with complex numbers, for example, it means the absolute value, so the modulus of 3 + 4i, say is sqrt(3^2 + 4^2)     (i.e. 5)
