CPhill but when i checked at the back of the book , the final answer isnt this , it is coming 4,913 .

i really cant understand it!i shall read your answer when i return!now im off to school!so bye!

OK, rosala....we can do it for 6 months.....then n will just equal (1/2)  (half  a year) in the equation

So we have

A = 4096(1 +.0625)^((1/2)*2) =

A = 4096(1 +.0625)^(1) =  Rs 4352  

This make sense....we just compounded the amount 1 time (for just 1/2 of a year) !!!

Does that help??

but CPhill , the question was given like this only and nothing more!my teacher did it using 6 months as i remember , maybe that n represents something else too or maybe u can decrease the rate to half according to half year and give no years!do u have any particular way of own to solve this?

4096 if he gave it for 12 1/2% per annum interest being componded half yearly?

OK , rosala....since the interest is being compounded twice a year we need to adust it to 12.5%/2 = 6.25% =  .0625 

So we have

A = 4096(1 +.0625)^(nt)       where n is the number of years  and t is the number of times compounded per year.....in this case, 2

So this simplifies to

A = 4096(1 +.0625)^(n*2) 

You didn't specify the number of years in your question....if you can give me that, I'll do an edit and compute the amount for you !!!

Problems are frequaently easier to solve if they have no denominators; multiply both sides by 4:

    4 x 1/4 (4x + 10)  =  4 x 8

         4x + 10  =  32

Subtract 10:

         4x  =  22

Divide by 4:

        4x  =  5.5

2a + 9  =  6a - 15

Get all the variable on one side; since 6a is bigger than 2a, subtract 2a from both sides:

2a - 2a + 9  =  6a - 2a - 15

     9  =  4a - 15

Add 15 to both sides:

     9 + 15  =  4a - 15 + 15

     24  =  4a

Divide both sides by 4:

     24 / 4  =  4a / 4

      6  =  a

It is just usual to use x.

Letters such as a, b, c, d, and e are often reserved for constants and u, v, w, x, y, and z are usually reserved for variables.

There is no mathematical "rule"  that requires that you use x for the variable.

3/14 x 8/18 x 12/20

Reduce 8/18 to 4/9 by dividing both by 2  --->  3/14 x 4/9 x 12/20

Reduce 12/20 to 3/5 by dividing both by 4  --->  3/14 x 4/9 x 3/5

The two 3's will cancel out the 9  --->  1/14 x 4/1 x 1/5

Reduce the 4 and the 14 by dividing both by 2   --->  1/7 x 2/1 x 1/5

Multiply the numerators together and the denominators together  --->  2/35

-9x + 1 = 80    subtract 1 from both sides

-9x = 79          divide both sides by -9

x = -79/9

|3(x-2)+7|=6   simplifying within the absolute value, we have

l3x - 6 + 7l = 6

l3x + 1l = 6      because lal = a  or  l-al = a  .... this implies that either

3x + 1 = 6       or       -(3x + 1) = 6

So, solving the first equation, we have

3x + 1 = 6       subtract 1 from both sides

3x = 5             divide both sides by 3

x = 5/3

And solving the second equation we have

-(3x + 1) = 6

-3x - 1 = 6         add 1 to both sides

-3x = 7              divide both sides bt -3

x = -7/3

To find the slope of the line you need two points and then plug them in to an equasion.

y2-y1

--------

x2-x1

The then fill in the numbers and it will give you the slope.

Exactly there is four on the inside and four on the outside and that equals eight.

lol i remember when i tried to buy 3 watermelons for this party i was having. Everybody stared at me like i was crazy....

No there's 8 sides on a square you dummy!
