OpenStudy (dan815):

shay!

OpenStudy (anonymous):

hello @dan815 and @aubreyk9616 what is the question ?

OpenStudy (luigi0210):

Question question please~

OpenStudy (anonymous):

please post the question

OpenStudy (anonymous):

you have to post the question so we can help...

OpenStudy (anonymous):

3. write an equation for the translation of y=6/x that has the asymptotes x=4 and y=5

OpenStudy (anonymous):

the original eqn is \[xy=6\] whose asymptotes are x=0 and y=0 shifting the asymptotes to x=4 and y=5 we need to shift the eqn to right by 4 units and upwards by 5 units hence the eqn becomes.... \[\left(x-4\right)\left(y-5\right)=6\]

OpenStudy (anonymous):

Awesome that's what I got

OpenStudy (anonymous):

good luck

OpenStudy (anonymous):

Do you know this one ?? What is the 20th term of the sequence that begins -4, 8,-16,32

OpenStudy (anonymous):

2097152

OpenStudy (anonymous):

Awesome thank you so much sweetie :) can you halp me with one more

OpenStudy (anonymous):

\[(-1)^n(2)^{n=1}\]

OpenStudy (anonymous):

n+1***

OpenStudy (anonymous):

it is geometric sequence which has a common ratio of -2 therefore... \[An=ar^\left( n-1 \right)\] where : An is any 'n'th term , 'a' is the first term and 'r' is the common ratio therefore...eqn comes \[A _{20}=(-4)*(-2)^{19}\] which is 2097152

OpenStudy (anonymous):

The 5th term in a geometric sequence is 140. the 7th term is 35. What are the possible values of the 6th term of the sequence

OpenStudy (anonymous):

if three number,say, a,b,c are in gp then c/b=b/a this is how u caluclate the common ratio if u simplify ...u get \[b ^{2}=ac\] therefore... in this question... a=140 c=35 therefore \[b ^{2}=140*35=4900\] therefore b= sixth term=70
