## anonymous 5 years ago Ok, this is the final one of this one......... Different one........ Suppose that y is directly proportional to x. (a) Use the given formula to find the constant proportionality k. (b) Then use y=kx to find y for x=6. y=-53 when x=7 k=

1. anonymous

OH MY GOD!!

2. anonymous

Shut it Anwar......it kept changing on me! lol.

3. anonymous

god, all your questions are in 1 form, just the numbers that were changed. why don't you just plug the new numbers in the formula

4. anonymous

Because I don't get it......if I knew, I wouldn't be bothering u guys!

5. anonymous

a) y is directly proportional to x so y=kx when x=7, y=-53. Substitute these in y=kx so -53=k*7 k=-53/7 b) y=kx=(-53/7)x x=6 so y=(-53/7)*6=calculator

6. anonymous

he/she is going to post another question in the same form very soon!!

7. anonymous

let's bet =))

8. anonymous

...........

9. anonymous

u know what, you can just copy paste the answer, then change the number lol

10. anonymous

Cant do that, I have tried!

11. anonymous

so, you get it yet?

12. anonymous

WHat does y=?

13. anonymous

question b?

14. anonymous

Yep!

15. anonymous

y=_when x is 6

16. anonymous

y=kx, you know k and x, so just plug them in. (-53/7)*6= copy that and google? you'll get the result.

17. anonymous

HAHA I don't think he/she knows google

18. anonymous

Didn't work.

19. anonymous

dude, its not nice to make fun of blondie -.-

20. anonymous

LOL

21. anonymous

Whatever Anwar, don't be a wingspan.

22. anonymous

do you have a calculator?

23. anonymous

Yes

24. anonymous

Yes I do.

25. anonymous

then you go - 5 3 / 7 x 6

26. anonymous

do you believe that she really can't do it?? I am sure that she's smarter than she seems.

27. anonymous

But........not in math!

28. anonymous

some of them don't lol. used to be one in my high school, cant even expand a(b+c)

29. anonymous

when are you going to post ur next question??

30. anonymous

I get the same equation from Google and my calculator, but it's saying the answer is incorrect.

31. anonymous

Well I still think she's smarter, but she is just messing with us.. if I am wrong, then I am sorry for all I have said so far.

32. anonymous

33. anonymous

whatever, nothing wrong

34. anonymous

(-53/7)*6=-318/7

35. anonymous

Too late on that one. If I do a similar exercise it will give me different numbers again.

36. anonymous

is you room on first floor?

37. anonymous

The distance D in miles to the horizon can be estimated by D (h)=1.22$\sqrt{h}$ where h is the height of the person above the ground in feet.

38. anonymous

How high does a person need to be to see 26 miles?

39. anonymous

D=26 26=1.22sqrt(h) find h yourself. and i'm gonna put a .22 in my brain/

40. anonymous

No clue.

41. amistre64

breath in ....breath out......breath in....................uhoh, now what?

42. anonymous

ok, which floor are you in just now?

43. anonymous

2nd'

44. anonymous

hmmm, not high enough. Last time I throw a boy from 2nd floor and nothing happened

45. anonymous

What's that got to do with how many feet?

46. anonymous

Ok, well thanks.......I guess I am going to bed and can hopefully get these things beat asap.

47. anonymous

well, nothing really. I already gave you the answer up there. So are you gonna jump out of ur window? if you wont then i will

48. anonymous

You did?

49. anonymous

How? I mean don't help me if it is going to cause you to become suicidal!

50. anonymous

yeah, I did it. and I'm standing behind you right now hihihi

51. anonymous

Sigh....

52. anonymous

i'ts not right. 26?

53. anonymous

no, find square root of h first then find h. im off to bed. btw, what are u studying? Art or business or something?

54. anonymous

Yeah. Both.

55. anonymous

Sqrt of h, then find h? Wth?

56. anonymous

cool, but reading those things sucks. why do you have to do this math stuff anyway? Even accounting is different. D (h)=1.22√h we know D=26 so 26=1.22√h √h=26/1.22 h=(26/1.22)^2 take a sleep then start this stuff again, if u was serious about ur ability lol

57. anonymous

i get accounting

58. anonymous

accounting has nothing to do with this kind of math right?

59. anonymous

I still dont get feet from that

60. anonymous

Not really.

61. anonymous

percents, etc, I get that.

62. anonymous

I bought mathway, but it doesnt seem to work for this stuff

63. anonymous

i got accounting last year, compulsory. hated it

64. anonymous

26/122^2 gets me nothing.

65. anonymous

Lol

66. anonymous

i think you need a personal tutor instead

67. anonymous

I got two weeks and I am done with math

68. anonymous

(26/1.22)^2=26^2/1.22^2

69. anonymous

yeah, you better be without it. 2weeks huh? damn those exams

70. anonymous

...........

71. anonymous

Thank GOD...........finally!

72. anonymous

Go to bed..........I am. Thanks. Bad part is, I still have a lot to do!

73. anonymous

See I can get the equations, it's figuring out all the mumbo jumo junk

74. anonymous

not the worst thing in the world lol. u should be happy. I have to stick to maths my whole life. fml.

75. anonymous

Hey, u must like it!

76. anonymous

no way i like it haha. i like those machinery stuff but not maths, which always comes along. I'm here just because fb anf utube waste me too much time. So I rather waste my time on helping people abit heer.

77. anonymous

Good deal!

78. anonymous

anyway. im off to bed too. the birds are chirping already lol. goognight

79. anonymous

morning for me though
