Answer: vertices of hyperbola=(0,+_6) we know vertices of hyperbola =(0,+_ b) b=6 eccentricity e=5/3 we know b^2(e^2-1)=a^2 6^2((5/3)^2)-1)=a^2 36(25/9-1)=a^2 36×16/9=a^2 a=6×4/3 a=8 now -x^2/a^2+y^2/b^2=1 -x^2/8^2+y^2/6^2=1 -x^2/64+y^2/36=1 Reply
Answer:
vertices of hyperbola=(0,+_6)
we know vertices of hyperbola =(0,+_ b)
b=6
eccentricity e=5/3
we know
b^2(e^2-1)=a^2
6^2((5/3)^2)-1)=a^2
36(25/9-1)=a^2
36×16/9=a^2
a=6×4/3
a=8
now
-x^2/a^2+y^2/b^2=1
-x^2/8^2+y^2/6^2=1
-x^2/64+y^2/36=1
