## Sariah Group Title Hi everybody i need help, Late i will be here i would like to know who is very smart with math in order to help me with a homework...? if is possible can you send me your answer to my E-mail: isabellaa38@gmail.com 3 years ago 3 years ago

1. King

post the question and everybody here who can help will try tto help...

2. vevernz

3. Sariah

4. Sariah

Hi vevernz. i will have all the question later

5. King

6. Sariah

ok in some minutes i will do it

7. vevernz

8. Sariah

9. salem123

okay every one is waiting for you to start

10. ktklown

I am also excited to hear Sariah's question. Who knows, maybe it will be algebra? or statistics? or geometry? or calclus? perhaps we should start taking bets

11. Sariah

12. salem123

well if it is geometry or statistics then i do not have any ideas

13. ktklown

i'm good at statistics

14. salem123

15. ktklown

it was computer science

16. salem123

so you majored in computer science

17. ktklown

yes

18. salem123

aha i see you are working now so

19. ktklown

yes

20. salem123

well i have done two years of geophysics and i am doing chemical engineering now

21. ktklown

aha, that is great

22. salem123

are you in U.S

23. ktklown

yes

24. salem123

i am international student in Canada

25. ktklown

what kind of things do you learn in a geophysics major?

26. Sariah

Waite iam trying to send an attaching

27. salem123

well in first year you go throw the general courses such chemistry and math and physics and i took statisitcs as well

28. salem123

second year was mixed of general courses but it was mostly major courses

29. salem123
30. ktklown

ah, so you didn't get m uch to the geophysics part yet

31. Sariah

$g(x)=3x$|dw:1321776430447:dw|

32. salem123

here is the link of the university I used to study geophysics in

33. Sariah

Find the domain of the function.

34. salem123

no

35. Sariah

Seleccione a. {x|x ≠ -7, 7} una respuesta. b. {x|x ≠ 0} c. all real numbers

36. salem123

the domain is going to be where ur denomerator is not zero

37. ktklown

(a), the denominator factors to (x+7)(x-7) which means it's undefined at x=7 and x=-7, since dividing by 0 is illegal, and at those values the denominator becomes 0

38. salem123

You for -infinity to -7 and from 7 to infinity

39. salem123

your domain is going to be (-infinity,-7) U (7,infinity)

40. Sariah

Seleccione una respuesta. a. {x|x ≠ -7, 7} b. {x|x ≠ 0} c. all real numbers d. {x|x > 49}

41. salem123

42. Sariah

43. ktklown

salem that's not quite right because everything between -7 and 7 is in the domain too, just not 7 and -7 exactly

44. salem123

45. salem123

i was trying to correct it any ways the right answer is a Sariah

46. Sariah

47. ktklown

48. salem123

49. ktklown

When is the denominator 0? Solve x^2-49==0, you get x^2==49, x==7 or -7, those are the places where the function is not defined

50. Sariah

yes it is the A

51. Sariah

is it the A

52. ktklown

do you have another question

53. Sariah

yes waite

54. ktklown

did you understand the first question?

55. Sariah

Find the value for the function. Find f(4) when f(4) = x^2 + 3x + 6 Question 2 Find the value for the function. Find f(4) when f(4) = x^2 + 3x + 6 Seleccione una respuesta. a. 34 b. 10 c. 22 d. -2

56. King

34 option a

57. Sariah

58. Sariah

ok 34

59. King

option a

60. Sariah

King thaks

61. King

any more questions;ure welcome

62. ktklown

sariah all you have to do is substitute 4 into the equation every place X appears. what grade are you in?

63. Sariah

Change the exponential expression to an equivalent expression involving a logarithm. 6^2 = 36 Seleccione una respuesta. a. \log_{36}6 = 2 b. \log_{6}2 = 36 c. \log_{2}36 = 6 d. \log_{6}36 = 2

64. King

$\log_{6}36=2$

65. King

that is log 36 base6 =2

66. King

what grade are u in sariah?

67. Sariah

The A then?

68. King

i dont understand the way u have typed ure options if u dont mind retyping them then i can tell u which option is answer use equation its easier

69. ktklown

sariah are you actually understanding any of this or just getting answers?

70. Sariah

Approximate the value using a calculator. Express answer rounded to three decimal places. 4.5^{1.4} Seleccione una respuesta. a. 8.213 b. 869.874 c. 4.545 d. 6.300

71. Sariah

72. Mimi_x3

Um, you can just use a calculator its common sense.

73. Sariah

Huy, I try but it doesn,t work...

74. Sariah

75. ktklown

76. ktklown

it will tell you the answer

77. Mimi_x3

78. ktklown
79. Mimi_x3

LOL, nice.

80. Sariah

Wao you don,t know that i choosed wrong this elective and now i don,t what to do...

81. Mimi_x3

Well, its your fault for picking the "elective" but can you at least try to do it.

82. Sariah

i am trying but it doesn´t work...

83. Sariah

Find the exact value of the logarithmic expression. \large\log_{10} 100

84. Mimi_x3

log100/log10 = ....

85. Sariah

Seleccione una respuesta. a. \frac{1}{100} b. -2 c. 20 d. 2
