10(1 +r)^20   = 96    divide both sides by 10

(1 + r)^20 = 9.6        take the log of both sides

log( 1 + r)^20  = log (9.6)    and we can write

20* log (1 + r)  = log(9.6)      divide by 20 on both sides

log (1 + r)  =  log(9.6) / 20     and this says

10^ [ log(9.6) / 20 ]  = 1 + r    subtract 1 form both sides

10^[log(9.6)/ 20] - 1  = r  = about  0.1197   = about 11.97%  per month

i got anime as an answer

This looks like the volume of a sphere :

(4/3) * 3.14 *  6^3  =   904.32 units^3

250,000 / 100 * $1.09  =

2500 * $1.09  =

$ 2725

Let's see how Spawn got that...

16% decrease means that each successive week, the number is 84% of the that of the previous week....so we have

50(.84)^N < 5       where N is the number of weeks  .....divide both dises by 50

(.84)^N  <  .10       take the log of both sides

log (.84)^N < log ( .10)     and we can write

N log(.84) < log (.10)     divide both sides by log (.84).....notice....since this is a negative quantity, we must reverse the inequality sign

N >  log(.10) / log(.84)

N > 13.2

But....since the answer must be in whole units, N = 14

2+2 = 4

19a-12-4a=57     simplify the left

15a - 12  = 57     add 12 to both sides

15a  = 69     divide  both sides by 15

a = 69 / 15    =  23 / 5

14 weeks

50(.84)^14 = 4.3539

x^13 / x^6  =

x^(13 - 6)  =

x^7

the answer to life, the universe, and everything (including your answer) is 42!  

but really, the answer is obviously 25.

W*F?!?

hello

x - 7  > -2       add 7 to both sides

x >  5

hey

5 / [x^2 + 6x + 8]   =  A / [x + 2 ]  + B / [ x + 4]

On the right, we can get a common denominator   and write

[ A ( x + 2)] + [ B(x + 4)]    =  5

(A + B)x + 2A + 4B  = 5

Equating co-efficients, we have

A + B  = 0     →   B = -A   (1)

2A + 4B  = 5     (2)

And subbing (1)  into (2), we have

2A + 4(-A)  = 5

-2A  = 5       →  A  = -5/2  = -2.5

And, using (1), B = 2.5

So......A + B = 0
