Question

help

Answer 1

a)list all factors of 18, don't forget the \(\pm\)

Answer 2

i put that?

Answer 3

no, you do that !!

Answer 4

u wont help

Answer 5

k lets see

Answer 6

i dont get it

Answer 7

what numbers go in to 18 evenly?

Answer 8

2, 3, 6, 9

Answer 9

also 1 and 18

Answer 10

kk

Answer 11

and like i said, don't forget the \(\pm\)
in front of each

Answer 12

do you know how to do synthetic division? it is real easy, but very hard to write here

Answer 13

lemme look it up

Answer 14

ok
your answer there is good

Answer 15

looks confusing.. but go on

Answer 16

\[~~1~~-3~~-7~~15~~18\]

Answer 17

that is a list of the coefficients
since you are dividing by \(x-3\) you put a \(3\) on the side \[

Answer 18

\[~~1~~-3~~-7~~15~~18\\3\]

Answer 19

then you drop down the 1

Answer 20

\[~~~1~~-3~~-7~~15~~18\\
3\\
~~~1\]

Answer 21

ok but you do not need that line above, the answer will be below
3 times 1 is 3

Answer 22

\[~~~1~~-3~~-7~~15~~18\\
3~~\\
~~~1\]

Answer 23

that didn't work, let me try again

Answer 24

\[~~~1~~-3~~-7~~15~~18\\
3~~3\\
~~~1\]

Answer 25

one more time

Answer 26

cant u draw it

Answer 27

\[~~~1~~-3~~-7~~15~~18\\
3~~~~3\\
~~~1\]

Answer 28

that second 3 should go under the -3

Answer 29

then \(-3+3=0\)

Answer 30

\[~~~1~~-3~~-7~~15~~18\\
3~~~~~~3\\
~~~1~~~~0\]

Answer 31

you need three rows all together
write it like i am trying to write it

Answer 32

kk

Answer 33

\[~~~1~~-3~~-7~~15~~18\\
3~~~~~~3~~~~~~0\\
~~~1~~~~0~~~~~~-7\]

Answer 34

\[~~~1~~-3~~-7~~15~~18\\
3~~~~~~3~~~~~~0~~~~-21\\
~~~1~~~~0~~~~~-7~~~~-6\]

Answer 35

your 1 should be on the bottom row, one more line and we are done

Answer 36

what about between 1 and 1?

Answer 37

?

Answer 38

\[~~~1~~-3~~-7~~15~~18\\
3~~~~~~3~~~~~~0~~~-21~~~-18\\
~~~1~~~~0~~~~-7~~~-6~~~0\]

Answer 39

i told you it was hard to write here

Answer 40

see if you can line them up
the 3 on further to the left
the 1 is directly under the top 1, but on the bottom row

Answer 41

second one is perfect

Answer 42

now we have to write the answer, which you get from the bottom line the coefficents are \[1,0,-7,-6\] so your answer to the division problem is \[x^3-7x-6\] with no remainder

Answer 43

to finish part b), there is no remainder, so \(x-3\) goes in to \(f(x)\) evenly and so \(f(x)\) factors as \[x^4-3x^3-7x^2+15x+18=(x-3)(x^3-7x-6)\]

Answer 44

good enough, i would use a lower case x

Answer 45

for part c) "factor completely" the answer is \[

Answer 46

\[(x - 3)^2 (x + 1) (x + 2)\]

Answer 47

how you are supposed to "show your work" for that one i have no idea

Answer 48

lets just skip the show ur work

Answer 49

ok fine last step is to graph

Answer 50

make it look like the top one

Answer 51

http://www.wolframalpha.com/input/?i=(x-3)(x%5E3-7x-6)

Answer 52

ew

Answer 53

the curve should cross the x axis at -2 and -1 but just come down and touch it at 3 and go back up

Answer 54

Golden.

Answer 55

good enug

Answer 56

yuuuuuuuuus

Answer 57

we have for more questions btw

Answer 58

four*

Answer 59

lol not if they were as long as that one

Answer 60

a) \[4800\times (.98)^t\] where \(t\) is years after 2006

Answer 61

b) since 2018 is 12 years after 2006 it would be \[1800\times .98^{12}\] which you compute with a calculator

Answer 62

typo

Answer 63

\[4800\times .98^{12}\]

Answer 64

u r so fast

Answer 65

http://www.wolframalpha.com/input/?i=4800*.98%5E12

Answer 66

graph should look something like this
http://www.wolframalpha.com/input/?i=4800*.98%5Ex+domain+0..50

Answer 67

3766.6402739270401602551808 do i put this

Answer 68

no round, it is populaton

Answer 69

37667 would make more sense

Answer 70

3767

Answer 71

yeah that

Answer 72

hows my grpah

Answer 73

usual crack added graph is beautiful

Answer 74

:')

Answer 75

i guess you are supposed to say there is a horizontal asymptote at \(y=0\) the x axis

Answer 76

domain is tricky not sure how to answer it
maybe you are just supposed to day "all real numbers" although that is silly for a word problem but whatever

Answer 77

the range is from wherever you start to 0, not including 0
maybe you could say the range is from your starting value, \(4800\) to 0

Answer 78

ok good enuf

Answer 79

i like the wolfram graph better, but whatever

Answer 80

i like sleeping better but here i am

Answer 81

next

Answer 82

i have no idea what a five number summery is

Answer 83

nor do i know what a box and whisker plot is
you are on your own with that one

Answer 84

k

Answer 85

hold on we can do the first one by cheating

Answer 86

kk

Answer 87

guess you cheated quicker than i did
where did you get that one?

Answer 90

ok you need to do some editing

Answer 91

first of all, get rid of "best answer"

Answer 92

lol

Answer 93

then everything at the end, from 4 down, has nothing to do with this question

Answer 94

and finallly you still need a box and whisker plot

Answer 95

you can use this, put it on its side

Answer 96

here is a somewhat nicer one

Answer 97

Answer 98

it dont show nun

Answer 99

gorguss

Answer 100

it does when you put the numbers in doe

Answer 101

ok go ahead doe

Answer 102

Enter comma separated data (numbers only):

Answer 103

i did but when i sent you the link it doesn't save it

Answer 104

send me the numbers

Answer 105

the numbers in the question doe

Answer 106

but i might mess up doe

Answer 107

10,10,15,17,19,25 copy and paste lol

Answer 108

ok doe

Answer 109

this is depressing

Answer 110

yeah usually it is put on its side for you high school students

Answer 111

like the one i wrote

Answer 112

ok good all you need is the standard deviation
and yes, this bull sht is depressing
most statistics is

Answer 113

the standard deviation is computed in that yahoo answer, the one with the square root sign

Answer 114

i gotta put all that?

Answer 115

yes, that is the standard deviation apparently

Answer 116

all?

Answer 117

hold on there is some mistake there

Answer 118

good thing i checked

Answer 119

das a good boi!

Answer 120

the data is \[10,10,15,17,19,25\]

Answer 121

but dis other guy has sum dif

Answer 122

right
so the mean is \[\frac{10+10+15+17+19+25}{6}=16\]

Answer 123

btw do i keep the box lookin thing empty?

Answer 124

yeah box is right

Answer 125

five numbers summary is wrong though because the used the wrong numbers for yahoo

Answer 126

great

Answer 127

i did it with an on line calculator, it is nothing
here

Answer 128

minimum is 10
first quartile 10
median 16
third quartile 19
maximum 25

Answer 129

i got that from here

Answer 130

do i erase a

Answer 131

https://www.easycalculation.com/statistics/five-number-summary.php

Answer 132

yeah copy what i wrote, not what yahoo wrote

Answer 133

do we gotta redo everything

Answer 134

the box plot is right

Answer 135

can we skip this and go back to it..

Answer 136

the mean is right

Answer 137

what i wrote above is right just copy it

Answer 138

there is only one thing left do to, the standard deviation, which is not hard

Answer 139

yes standard deviation is all that is left

Answer 140

i will write it out for you

Answer 141

\[(10-16)^2+(10-16)^2+(15-16)^2+(17-16)^2+(19-16)^2+(25-16)^2\]
\[=6^2+6^2+1+1+3^2+9^2\]
\[=164\]
\[\sqrt{164}=12.8\]

Answer 142

wrong but we can fix it in a jif

Answer 143

is it fixed

Answer 144

\[\sqrt{\frac{164}{5}}=5.73\] now it is fixed

Answer 145

oh just the last part

Answer 146

skip the last line aboe

Answer 147

right

Answer 148

you need the \(168\)
then divide by 5, take the square root

Answer 149

i mean 164,whatever

Answer 150

le juicy?

Answer 151
