Question

What is the equation of the following graph?
Answers:
x2/9 - y2/36=1
x2/35-y2/9=1
x2/36+y2/9=1
x2/9+y2/36=1

Answer 1

major axis is along y

Answer 2

ok?

Answer 3

x^2/a^2 + y^2/b^2 = 1

a must be less than b

Answer 4

check your options and figure out which has a < b

Answer 5

The standard formula for a tall ellipse centered at (0,0) is
\[\frac{ x^2 }{ b^2 } + \frac{ y^2 }{ a^2 } = 1\]
Where a the length from the center to the edge of the major (longer) axis and b is the length from the center to the edge of the minor axis.

Answer 6

ok so my answer I got is c

Answer 7

@DDCamp

Answer 8

c is not correct

Answer 9

If its not c then its definitely d

Answer 10

you have it !

Answer 11

yes but u must understand why it is the vertices is in (0, +-a) so it is (0, +-6) replacing that in the equation for the ellipse u get the answer d

Answer 12

ok Ima write that down
