Question

I need to identify the conic section for these 10 questions. I need help to find out whether they are Elipse, Hyperbole, or Circle. Hold on I shall post the questions.

Answer 1

1. x^2/9 + y^2/100 =1

Answer 2

2. y^2/25 - x^2/1 = 1

Answer 3

3.( x^2)/(28) - y = 0

4. (y^2)/(16) + (x^2) / (16) = 1

Answer 4

5. (x^2) -( (y-8)^2 / (36) ) =1

Answer 5

6. (1)/(80) y^2 =x

7. (y+2)^2 / (49) + (x^2)/ (4) = 1

8. (x-2)^2 + (y+3)^2 = 16

Answer 6

9. x^2 -10x+25 = y

10. ((x-11)^2 / (144)) - ((y-1)^2 /(81)) =1

Answer 8

I think #1 is elipse and #2 is hyperbole

Answer 9

and I think #10 is Elipse

Answer 10

here is a website I just googles that has a nice summary of conic section equations

http://math2.org/math/algebra/conics.htm

and 1 is an ellipse
2 is a hyperbola

good luck

Answer 11

wait am I right for #10?

Answer 12

can someone please tell me 3-9? :(

Answer 13

@mustry ?

Answer 14

@hba ?

Answer 15

@radar

Answer 16

I need 3-10

Answer 17

Wouldn't 4. be a circle?

Answer 18

that's what I was thinking. what about 3?

Answer 19

Ima lookin at 3.

Answer 20

OH WAIT! it says Parabola is an option too

Answer 21

Is 6 a parabola?

Answer 22

Wouldn't 3 be a parabola??

Answer 23

I believe so, what about 6?

Answer 24

And isn't 10 ellipse?

Answer 25

I think 6 also a parabola.

Answer 26

I think so too. Is 10 ellipse?

Answer 27

?

Answer 28

@mustry

Answer 29

I am not sure of 10. The fact that it is a difference confuses me otherwise it would be a circle (I think), but with the minus, I am confused.

Answer 30

Hm, well what about 5, 7, 8, and 9?

Answer 31

I think 9 is a parabola.

Answer 32

8. would be a circle whose origin is not at (0,0)

Answer 33

alright, I just need 5, 7, and 10

Answer 34

isn't 7 a hyperbola?

Answer 35

5 is similar to 10 (whatever that is !!)

Answer 36

isn't 7 a hyperbola?

Answer 37

7 circle and 5 and 10 hyperbola. These are guesses.

Answer 38

I am sorry it is obvious I need to review the conics. lol

Answer 39

thank you so much lol
