Question

can anyone help me more with equations of ellipses and hyperbolas? i would love to get passed this stuff already. been on it for a few weeks.

Answer 1

I'd love to your problems of ellipses and hyperbolas.

Answer 2

the problem is \[4x ^{2}+9y ^{2}-8x-18y-23=0\]
find the center and separate the values with a comma

Answer 3

Are you telling me that
center (1,1)
Major axis vertices (4,1) , (-2,1)
Minor axis vertices (1,3) , (1,-1)
Foci (1 + sqrt 13,1) , (1 - sqrt 13,1)
were wrong???

I would like to know because I am sure it is correct.

Answer 4

well on the assignment i was doing, i can only miss 2 questions. 3 were wrong. so i exited out of the assignment because i was going to fail it anyways. so then i had to start over. and now it's not always the same questions

Answer 5

Well this one was the same one... I think on the second one you didn't type it in correctly. I think you missed a sign. Now when it comes to the sqrt 13, I don't know if it want you to use a calculator and estimate or use the sqrt 13.. You will have to know which one they want.

Answer 6

I will stick with you until you get enough correct if you want. If not, I will move on

Answer 7

you have to figure out the square & round it. but yeah, it's the same one. but it's very uncommon that it will repeat questions. i have no idea at all how to do any of this. kinda the reason why i have been on it for almost a month now

Answer 8

Put those answers in and tell me if they were wrong.

Answer 9

i just brought the assignment back up, it's not the same question.

Answer 10

What is the question?

Answer 11

find the center:
\[-4x ^{2}+y ^{2}-8x-12y+36=0\]
use commas to separate the values

Answer 12

How about (-1,6) .. does it say it is an hyperbola?

Answer 13

yeah, it's a hyperbola

Answer 14

Next question.
find the vertices for the hyperbola.
write your answer as (x1,y1),(x2,y2)

Answer 15

(-2,6),(0,6)

Answer 16

find the foci for this hyperbola
write your answer as (x1,y1),(x2,y2)
round if necessary to the nearest hundredth.

Answer 17

(-3.24,6),(1.24,6)

Answer 18

find the equation that represents the asymptotes of this hyperbolas
A.\[y=\pm2x\]
B.\[y-6=\pm1/2(x+1)\]
C.\[y-6=\pm2(x+1)\]
D.\[y=\pm1/2x\]

Answer 19

A.

Answer 20

WAIT

Answer 21

Did you put it in... I don't think it is correct. I forgot about the center..

Answer 22

no not yet

Answer 23

It is C.

Answer 24

find the center of this ellipse:
\[9x ^{2}+y ^{2}+36x-4y+31=0\]
use commas to separate the value

Answer 25

(-2,2)

Answer 26

find the major axis vertices for the ellipse
write your answer in this form (x1,y1),(x2,y2)

Answer 27

(-2,5),(-2,-1)

Answer 28

find the major axis vertices for this ellipse
write your answer in this form (x1,y1),(x2,y2)

Answer 29

minor not major

Answer 30

(-3,2),(-1,2)

Answer 31

is that the minor?

Answer 32

Yes

Answer 33

find the foci vertices for this ellipse
write your answer in this form (x1,y1),(x2,y2)
round if necessary to the nearest hundredth

Answer 34

(-2,5.16),(-2,-1.16)

Answer 35

thanks!
