Answer:

Option (B)

Step-by-step explanation:

Given system of equations is,

x² + y² = 9 ------(1)

\frac{x^2}{25}-\frac{y^2}{36}=1 -------(2)

From equation (1),

x² = 9 - y²

Substituting these values in equation (2),

\frac{9-y^2}{25}-\frac{y^2}{36}=1

Therefore, Option (B) will be the correct option.

determine if the sequence is geometric or arithmetic and find the ratio or difference. -1, 6, -36, 216
andrew-mc [135]
The sequence is an geometric progression;
Nth=a₁r^(n-1)
a₁ is the first term=-1
r=ratio=a₂/a₁=6/-1=-6

Nth=-1(-6^(n-1)

NTh=an

a
₁=-1(-6⁰)=-1
a₂=-1(-6¹)=6
a₃=-1(-6²)=-36
a₄=-1(-6³)=216

therefore this serie is rising at an increasing fast speed, it is an geometric progression.
