Find the Properties (x^2)/25+(y^2)/4=1

Problem

(x2)/25+(y2)/4=1

Solution

1. Identify the type of conic section. Since the equation is in the form (x2)/(a2)+(y2)/(b2)=1 with a2>b2 it is a horizontal ellipse centered at the origin (0,0)

2. Determine the values of a and b We have a2=25 and b2=4 which gives a=5 and b=2

3. Calculate the distance to the foci c using the formula c2=a2−b2

c2=25−4

c2=21

c=√(,21)

4. Find the vertices and co-vertices. The vertices are at (±a,0) and the co-vertices are at (0,±b)

Vertices⇒(±5,0)

Co-vertices⇒(0,±2)

5. Locate the foci. The foci are at (±c,0)

Foci⇒(±√(,21),0)

6. Compute the eccentricity e using the formula e=c/a

e=√(,21)/5

Final Answer

Center: *(0,0), Vertices: *(±5,0), Foci: *(±√(,21),0), Eccentricity: √(,21)/5
