thanks for the detailed answers. but asinus's answer does not agree with the others. why not?

atdhvaannkcse!

You can set this up as a simple ratio:

7280/520000 = x/650000

x= 9100 tax

So, as of yesterday I was searching the internet looking for memes when I came across a african american male asking what is nine plus ten but he said 21, is he correct?

\(19_{10} = 21_9\)

FV=PV(1+i)^n

a) i = .0568/12 = .0047333 per period     periods = 6 yrs x 12 mos = 72

     FV = $ 21074.13

b) i = .0568/2 =.0284 per period              periods = 6 yrs x 2 = 12

     FV=  $ 20991.14

there's a thing called a calculator

indeed

that genius is indeed correct

I do not see my post to this question, so I will repost:

From FIRST post we found

Speed at top of window = 8.9875 m/s    Distance from roof top to top of window 4.12 m

NOW

Time to travel past window = .125    then to ground 1 sec  = total 1.25 sec

x = distance to top of window from ground

       =  xo+vot+1/2 at^2       where xo=0   vo= 8.9875 m/s (NOT zero as I previously used)  t= 1.125

         = 8.9875 (1.125) + 1/2(9.8)(1.125^2) = 16.31m

               16.31 m  <-------- add THIS to the distance from the top of the building to top of window

     16.31 + 4.12 = 20.43 m = building height      (sorry for the previous error)

x^2 +ax+b=(x+2)^2-3

\(\begin{array}{|rcll|} \hline x^2 +ax+b &=& (x+2)^2-3 \\ &=& x^2+4x+4-3 \\ &=& x^2+\underbrace{4}_{=a}x+\underbrace{1}_{=b} \\ \hline \end{array}\)

a=4 and b=1

michael writes down 4 different factors of 60.

he adds the factors together he gets a number greater than 20 but less than 35.

what 4 factors could michael have written down?

1. 1 + 2 + 3 + 20 = 26

2. 1 + 2 + 5 + 20 = 28

3. 1 + 2 + 6 + 12 = 21

4. 1 + 2 + 6 + 20 = 29

5. 1 + 2 + 10 + 12 = 25

6. 1 + 2 + 10 + 20 = 33

7. 1 + 3 + 5 + 12 = 21

8. 1 + 3 + 5 + 20 = 29

9. 1 + 3 + 6 + 12 = 22

10. 1 + 3 + 6 + 20 = 30

11. 1 + 3 + 10 + 12 = 26

12. 1 + 3 + 10 + 20 = 34

13. 1 + 5 + 6 + 10 = 22

14. 1 + 5 + 6 + 12 = 24

15. 1 + 5 + 6 + 20 = 32

16. 1 + 5 + 10 + 12 = 28

17. 1 + 6 + 10 + 12 = 29

18. 2 + 3 + 5 + 12 = 22

19. 2 + 3 + 5 + 20 = 30

20. 2 + 3 + 6 + 10 = 21

21. 2 + 3 + 6 + 12 = 23

22. 2 + 3 + 6 + 20 = 31

23. 2 + 3 + 10 + 12 = 27

24. 2 + 5 + 6 + 10 = 23

25. 2 + 5 + 6 + 12 = 25

26. 2 + 5 + 6 + 20 = 33

27. 2 + 5 + 10 + 12 = 29

28. 2 + 6 + 10 + 12 = 30

29. 3 + 5 + 6 + 10 = 24

30. 3 + 5 + 6 + 12 = 26

31. 3 + 5 + 6 + 20 = 34

32. 3 + 5 + 10 + 12 = 30

33. 3 + 6 + 10 + 12 = 31

34. 5 + 6 + 10 + 12 = 33

x = number of girls   then

1/5x = number of boys

377 + 1/5 x = adults

All of these added together = 2113

x + 1/5 x  + 377 + 1/5 x = 2113

7/5 x = 1736

x=girls=1240          (boys = 248   adults = 625)

The answer to 9+10=19

Percent just means 'hundredth'  of something.   So  3% of  20    is just 3 hundredths of 20

that is 3/100       x     20 .

14%   of     9%     is 14 hundredths  of  9 hundredths    or  14/100     x    9/100.   That's all there is to it.

Factors of 60 are  1 2 3 4 5 6 10 12 15 20 30 60

Pick four that you like that will fit the problem:

here is one set    2  3   5  15      there are a lot more.....

Thanks Heureka,

I'll go one step further:

\((-1)^n-(1)^n= (-1)^n - 1 \)

If n is even then this is      1-1=0

if n is odd then this is        -1-1=-2

hello is please tu calculator

4x - 3 =x + 9

\(4x - 3 =x + 9\\ 3x - 3 = 9\\ 3x=12\\ x=4 \)

hello is please tu calcolatur

hallo is please colc

thanks!

Hi Guys could anyone tell me what is the derivative of (cos x - sin x)^2 and the tan x/ 1- cot x??? i need it ASAP Thank you guys!!!
