Give the equation of the circle centered at the origin and passing through the point (0,-8)

Norma-Jean [14]

Answer:

The answer to your question is x ² + y² = 64

Step-by-step explanation:

Process

1.- Find the length of the radius

C (0, 0)

P (0, -8)

d = $\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2} }$

d = $\sqrt{(0- 0)^{2}+ (-8 - 0)^{2} }$

d = $\sqrt{64}$

d = 8

2.- Find the equation of the circle

$(x - h)^{2} + (y - k)^{2} = r^{2} \\$

h = 0 and k = 0

$(x - 0)^{2} + (y - 0)^{2} = 8^{2}$

x² + y² = 64

Find the center, vertices, and foci for the ellipse 25x^2+64y^2=1600

Ronch [10]

Answer:

Step-by-step explanation:

Answer:

Data

Equation 25x² + 64y² = 1600

Process

1.- Divide all the equation by 1600

25x²/1600 + 64y²/ 1600 = 1600/1600

-Simplify

x²/64 + y²/ 25 = 1

2.- Equation of a horizontal ellipse

3.- Find a, b and c

a² = 64 a = 8

b² = 25 b = 5

-Calculate c with the Pythagorean theorem

a² = b² + c²

-Solve for c

c² = a² - b²

-Substitution

c² = 8² - 5²

-Simplification

c² = 64 - 25

c² = 39

-Result

c = √13

4.- Find the center

C = (0, 0)

5.- Find the vertices

V1 = (-8, 0) V2 = (8, 0)

6.- Find the foci

F1 = (-√13, 0) F2 = (√13, 0)
