7. anonymous

8. anonymous

9. anonymous

okay every one is waiting for you to start

10. anonymous

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. anonymous

12. anonymous

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

13. anonymous

i'm good at statistics

14. anonymous

15. anonymous

it was computer science

16. anonymous

so you majored in computer science

17. anonymous

yes

18. anonymous

aha i see you are working now so

19. anonymous

yes

20. anonymous

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

21. anonymous

aha, that is great

22. anonymous

are you in U.S

23. anonymous

yes

24. anonymous

i am international student in Canada

25. anonymous

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

26. anonymous

Waite iam trying to send an attaching

27. anonymous

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

28. anonymous

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

29. anonymous
30. anonymous

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

32. anonymous

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

Find the domain of the function.

34. anonymous

no

35. anonymous

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

36. anonymous

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

37. anonymous

(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. anonymous

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

39. anonymous

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

40. anonymous

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

41. anonymous

42. anonymous

43. anonymous

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

44. anonymous

45. anonymous

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

46. anonymous

47. anonymous

48. anonymous

49. anonymous

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. anonymous

yes it is the A

51. anonymous

is it the A

52. anonymous

do you have another question

53. anonymous

yes waite

54. anonymous

did you understand the first question?

55. anonymous

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. anonymous

34 option a

57. anonymous

58. anonymous

ok 34

59. anonymous

option a

60. anonymous

King thaks

61. anonymous

any more questions;ure welcome

62. anonymous

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

63. anonymous

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. anonymous

$\log_{6}36=2$

65. anonymous

that is log 36 base6 =2

66. anonymous

what grade are u in sariah?

67. anonymous

The A then?

68. anonymous

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. anonymous

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

70. anonymous

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. anonymous

72. Mimi_x3

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

73. anonymous

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

74. anonymous

75. anonymous

76. anonymous

it will tell you the answer

77. Mimi_x3

78. anonymous
79. Mimi_x3

LOL, nice.

80. anonymous

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. anonymous

i am trying but it doesn´t work...

83. anonymous

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

84. Mimi_x3

log100/log10 = ....

85. anonymous

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