deleted.................  I am not sure about my answer

You can have: 4^4 = 256 - different sum of money.

  Well, N....what do YOU think is the answer......YOU have to do some of the work to learn anything.....we can't spoonfeed all of the answers to you....

    trust yourself a bit and answer the question with what YOU think the answer is....maybe it is correct....maybe not.....but TRY!

Umm this is my only question today!

Hex   4 A 7 ?  divisible by 17

4 x 16^3 +

10 x 16^2 +

7 x 16 = 19056       19056/17 = 1120.94117      1121x 17= 19057

Untis digit needs to be 1

4 x 16^3 +

10 x 16^2 +

7x 16 +

1               =  19057    which is divisible by 17

4A70 [Hex Number]
3210=[16^3 * 4] + [16^2 * 10] + [16^1 * 7] + [16^0 * 0]
         =   16,384    +   2560        +     112         +      0
         =19056 mod 16 = 16 - Since the remainder is 1 < 17, it therefore follows that the first digit is 1. So, the Hex number would be:4A71 =19,056 + 1 =19,057 mod 17 in base 10 = 0.

Im altough not sure! 

So the answer is (C)? 

18% of 95 is 17.1 

17.1*5= -85.5 Meters? 

18% of 95 meters every second

What is 18% of 95 ?    It goes this far every second

    once you calculate that number, multiply it by 5 seconds.....  

Well I'm leaving this in your judgemnet to figure that part out. we have presented how to solve for the solution.

So (B)? 

You want to make both denomiator's in this problem the same, So you have: \(\frac{2}{3} - \frac{2}{6} = ?\)We can find the LCM

(Least common mulitple) of these numbers, which is 6 because 6*1 = 6 and 3*2 = 6 So now we know we have \(\frac{2}{6}\)but we need to change \(\frac{2}{3}\) to a denomiator of 6, we

can do this by simply changing it to six and to find the numerator we divde 6 by 3 and then multiply the quotient by the numerator of 2/3 which is to

so 2*2 is equal to 4 so now we have \(\frac{4}{6}-\frac{2}{6}=\frac{2}{6}\) 

So now we know \(\frac{2}{6}\) is or answer. whic reduces to \(\frac{1}{3}\)

Oh (B) 

Thanks EP so what Letter would it be 

A. 

B. 

C. 

D. 

Not to be rude 

Thanks Chris, that should help Juriemagic to understand the rectangle idea.

The rectangles can be represented in a number of different ways.  

They are estimates of  the area under the curve and in certain cases they can give exact areas.

I'd just like to talk a little more about this.

Jurimagic,

You know how the integral sign looks like a stylized S   ?

Well that is not a coincidence.

That S stand for sum. 

Consider definite integrals where there is a number at the bottom B and a number at the top T    and it is dx

The integral will will give the sum of the areas of the rectangles that are under she curve between B and T.

The rectangles will be evenly spaced along the x axis between the lowest value B and the highest value T

The width of the rectangles is the difference between 2 adjacent x values.  ie    dx     d stands for difference.

For example if two adjacent x values are 3 and 4 then the difference between them is 4-3=1   This is the width of the rectangle.

ONLY with integration the difference between the x values approaches 0  

So a definite integral give the sum of an infinite number of infinitely thin rectangles and hence gives the accurate area under the curve.

I am not sure if you can understand what I am saying when I have not any diagram to show you.

Try drawing what i have described.

If you want me to try and explain better ask and I will try.  :)

2/3 - 2 (1/6) = 2/3 - 2/6

                    = 4/6 - 2/6 = 2/6 = 1/3

My goodness you are a lazy git.  Three questions in a row and you are too lazy to even attempt to present any of them properly.

Thanks (Ep) (: 

Ohh I see Thanks! 

thank you kindly.....appreciate!!..

Step 2 SHOULD be   -26.7  *  (+3)      SHe multiplies by -3

Ah....you a referring  to the concept of the "Riemann Sum"

Here is a very good tutorial on this....it explains it much more clearly than I can :
