i replied it just a moment before

3. Bri_Love

yeah i didnt get it so i re posted to get different help

4. Bri_Love

@bookaholic do you know this one

5. bookaholic

I'm looking it over to see if I can solve it

6. Bri_Love

ok

7. bookaholic

Roh how did you solve it?

8. Roh

i think we have to break the exponents of 2^20 lets get togather and break the power

9. bookaholic

2^20=1048576

10. Bri_Love

is that the answer for a or B?

11. Roh

lolz i mean we have to break the power no need of just calculating this because we should figure out how many 2^3 is inside this figure

12. bookaholic

niether and to get the number of bits youd multiply that by 2^3 or 8

13. Bri_Love

Whattt

14. PinkPanda

10^-10 x 1000 100 = 10^3 so 10^-10 x 10^3 add exponents... 10^-7 m

15. bookaholic

the number of bits in a megabyte is 8388608 buy Im not sure how to put that as a power of 2

16. Bri_Love

@PinkPanda what one it that?

17. PinkPanda

the first one

18. Bri_Love

A ok do you ahve B yet?

19. PinkPanda

ultraviolet rays is 0.000010 m 0.00000038<visible light<0.00000076

20. Bri_Love

ok and do you have task 3?

21. PinkPanda

one sec

22. Bri_Love

ok

23. PinkPanda

i gonna have to write this one out so hold on

24. Roh

the number of MB in Bytes are : 2^16 . 2^4 and i am trying to find out how to make it based on 2^3

25. PinkPanda

Model the population growth of chessvile with an exponential function (y=50,000 x 1.07^x. Use the function from the first step to find the population of chessville in 2011,2012,2013,2014 (53,500: 57,245: 61,252: 65,540). model the population decline of checkersville with an exponential function ( y= 70,000 x .96^x) Use the function from the third step to find the population of checkersville in 2011,2012,2013,2014 (67,200: 64,512: 61,932: 59,454) Compare the result from the second step and the fourth step. Determine when the population of chessville first exceeds that of chessville ( on January 1, 2014 the population of chessville is 65,540 and the population of checkersvile is 59,454. So the population of chessvill will exceed that of checkersville sometime during the year of 2013

26. Bri_Love

ok that last thing you posted^ what one is that for???

27. Bri_Love

@PinkPanda

29. Bri_Love

what is for B on task 2?

30. PinkPanda

To find the number of megabytes in 1 gigabyte, divide the number of bytes in 1 gigabyte by the number of bytes in 1 megabyte (2^30/2^20 = 2^10 mb). to find the number of bits in 1 gigabyte, multiply the number of bytes in 1 gigabyte by the number if bits in 1 byte ( 2^30 x 2^3 = 2^33 bits).

31. Bri_Love

What?????? Im so confused!!!!

32. Bri_Love

oh wait I see how you did that ok i get it and that is for B?

33. PinkPanda

yes that is for 2b

34. Bri_Love

ok and then which one is for a and b on #3 that you did?

35. PinkPanda

the really big message i did is for task 3 that one has no part a and b its just one q

36. Bri_Love

oh ok thanks!

37. PinkPanda

No problem!
