i got f(n)=4.5n
ccswims
  • ccswims
yea, your right, lol. ^.^
anonymous
  • anonymous
can you help me with this one?
Ineedhelpfast12
  • Ineedhelpfast12
4.5n
anonymous
  • anonymous
b) Suppose the total cost for n tickets is $36. What is the total cost if one more ticket is purchased?
ccswims
  • ccswims
ok, now just plug in 36 for f(x)
Ineedhelpfast12
  • Ineedhelpfast12
36+4.50
ccswims
  • ccswims
no
ccswims
  • ccswims
36 = 4.5n
anonymous
  • anonymous
ok thanks
anonymous
  • anonymous
thanks for being helpful. mind if you help me with other ones? @ccswims
ccswims
  • ccswims
sure!
anonymous
  • anonymous
is 20-2*3^2
anonymous
  • anonymous
does it equal 2?
ccswims
  • ccswims
yes :)
anonymous
  • anonymous
can you show me step by step how to do it
ccswims
  • ccswims
ok, use PEMDAS, or order of operations. Parenthesis Exponents Multiply Divide Add Subtract that is the order you go through things if you have a problem you just showed me
ccswims
  • ccswims
since we have no parenthesis, but we do have exponents, we would simplify the exponent first
anonymous
  • anonymous
ok
ccswims
  • ccswims
that would leave us with 20 - 2*9 now
ccswims
  • ccswims
then we have multiplication, so we do 2*9 next
ccswims
  • ccswims
and then subtract 20 - 18 last
anonymous
  • anonymous
ok thx
anonymous
  • anonymous
5*2^2 / 2+8 = 18 right?
ccswims
  • ccswims
yes
anonymous
  • anonymous
if s=4 and t=8 what is (st)^2 / (st^2)
anonymous
  • anonymous
@ccswims
ccswims
  • ccswims
ok, so according to PEMDAS parenthesis always comes first
ccswims
  • ccswims
so with that information, what can you do by yourself?
anonymous
  • anonymous
how is the equation set up?
ccswims
  • ccswims
(4*2)^2 / (4*2^2)
ccswims
  • ccswims
WAIT
ccswims
  • ccswims
(4*8)^2 / (4*8^2)
ccswims
  • ccswims
for some reason i put 2 instead of 8 in the first expression i gave you
anonymous
  • anonymous
oh
ccswims
  • ccswims
so work on (4*8)^2 / (4*8^2) and then tell me your answer when you get it
anonymous
  • anonymous
1?
anonymous
  • anonymous
@ccswims
ccswims
  • ccswims
not quite. when you multiply 4*8 you get 32 32^2 / (4*8^2) now, the (4*8^2) part can get tricky because i used to think you need to multiply 4*8 first then use the exponent. but what that parenthesis tells us is that its actually 4 * 8^2 and the 8 is the only one with the exponent. so its actually 32^2/256
ccswims
  • ccswims
then its 1024/256 = 4
ccswims
  • ccswims
so the answer is 4
anonymous
  • anonymous
can you help me with a few more plz
ccswims
  • ccswims
yea sure
ccswims
  • ccswims
do you get the problem tho?
ccswims
  • ccswims
like, do you understand how i got 4?
anonymous
  • anonymous
yeah i saw my mistake
ccswims
  • ccswims
ok, as long as you understand how to do it :)
anonymous
  • anonymous
ok so if s=4 and t=8 what is 2s^2-t^3 / 16
anonymous
  • anonymous
just tell me the set up and ill try to get it
ccswims
  • ccswims
ok, you you need to plus in 4 for s and 8 for t 2*4^2 - 8^3 / 16
anonymous
  • anonymous
ok
anonymous
  • anonymous
i messed up i think @ccswims
anonymous
  • anonymous
i got 0
ccswims
  • ccswims
the answer is actually 1, can you show me your work so i can see where you went wrong?
anonymous
  • anonymous
ok
ccswims
  • ccswims
WAIT, never mind you got it right
ccswims
  • ccswims
i messed up and divided 32 by 32, and you need to subtract 32 and 32
ccswims
  • ccswims
which im guessing you did because the answer is 0 and you got 0.
anonymous
  • anonymous
2*4^2-8^3 / 16 2*16-512 / 16 32-512 / 16 32-32
ccswims
  • ccswims
yes, you got it right
ccswims
  • ccswims
it was my mistake. your getting the hang of equations like this really well
anonymous
  • anonymous
so is it 1 or 0?
ccswims
  • ccswims
it is 0, you were right :)
anonymous
  • anonymous
hay!!!!!!! lol
anonymous
  • anonymous
thx. can you help me with 4 more?
ccswims
  • ccswims
yes :)
anonymous
  • anonymous
dang im invisible lmfao
ccswims
  • ccswims
lol nah i see you
anonymous
  • anonymous
YAY :D
anonymous
  • anonymous
i can help
anonymous
  • anonymous
ok
anonymous
  • anonymous
here is the next one
anonymous
  • anonymous
just screenshot it
anonymous
  • anonymous
\[2[(8-4)^{5} \div 8]\] \[22+1^{3}+(3^{4}-7^{2})\] ____________________________ 2^3
anonymous
  • anonymous
i have no clue
anonymous
  • anonymous
i cant screenshot it its paper
anonymous
  • anonymous
this problem is confusing
ccswims
  • ccswims
are they 2 different problems?
anonymous
  • anonymous
is that all one problem?
anonymous
  • anonymous
yeah one problem
anonymous
  • anonymous
i can skip it if u want
anonymous
  • anonymous
no no
anonymous
  • anonymous
well the top part is 256
anonymous
  • anonymous
ops its only the top one! ha lol
ccswims
  • ccswims
yea, just remember what we talked about in the beginning, PEMDAS, use your order of operations
anonymous
  • anonymous
the one that starts with 2?
anonymous
  • anonymous
yeah
anonymous
  • anonymous
the answer is 256
ccswims
  • ccswims
and the bottom one is a fraction right?
anonymous
  • anonymous
i dont need to do the bottom
anonymous
  • anonymous
okie :P
anonymous
  • anonymous
so how do i do this?
anonymous
  • anonymous
8-4=?
ccswims
  • ccswims
wait, i got 704?
anonymous
  • anonymous
4
anonymous
  • anonymous
4^5
anonymous
  • anonymous
i know the answer is 256 because my teacher gave me the answer to this one but he wants me to do the work
anonymous
  • anonymous
im showing u how
anonymous
  • anonymous
ok so parentheses first?
anonymous
  • anonymous
so far we have|dw:1439253355452:dw|
anonymous
  • anonymous
then|dw:1439253413305:dw|
anonymous
  • anonymous
then what
anonymous
  • anonymous
@ccswims
anonymous
  • anonymous
i dont know what to do
anonymous
  • anonymous
|dw:1439253625948:dw|
anonymous
  • anonymous
thats 128
anonymous
  • anonymous
ok so what is the absolute value of 128?
anonymous
  • anonymous
i dont know
anonymous
  • anonymous
128
anonymous
  • anonymous
oh 256
ccswims
  • ccswims
multiply use your order of operations
anonymous
  • anonymous
absolute value is the number but positive
anonymous
  • anonymous
ok i need help with 3 more
anonymous
  • anonymous
so if you have the absolute value of -128 you would get 128
anonymous
  • anonymous
i meant 2 more
anonymous
  • anonymous
we didnt finish the steps :S
anonymous
  • anonymous
3m^2-n; m=2, n=6
anonymous
  • anonymous
@ccswims
anonymous
  • anonymous
never mind i got it its 6
anonymous
  • anonymous
ok thank you guys for helping so much. i need to go bye
anonymous
  • anonymous
bye
