What conic section degenerates into a line?<br> Ellipse<br> Circle<br> Hyperbola<br> Parabola
musickatia [10]

Answer:

The answer is "parabola."

Step-by-step explanation:

Parabola- this is a symmetric open-plane curve that is formed by the intersection of a cone with a plane parallel to its side.

Degenerate Conic- this is generated when a plane intersects with the vertex of the cone.

Plane- a flat, two-dimensional surface that extends infinitely far.

Cone- a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex.

In Mathematics,<em> </em><em>t</em><em><u>he degenerate form of a parabola is a line or two parallel lines.</u></em> The <u><em>degenerate form of a hyperbola is two intersecting lines while a degenerate form of a circle or an ellipse is a singular point. </em></u>

Thus, the answer is parabola.

maks197457 [2]

Answer:

Let c represent the number of cows

Let h represent the number of horses

There are 2 more horses than cows in a field

⇒there are extra two horses are always than cows

⇒ horses-cows =2

⇒ hourses=2+cows

⇒ h =2+c

There are 16 animals in the field in all.

⇒ h +c=16

⇒ (2+c)+c=16

⇒ 2+2c=16

⇒ 2+2c-2=16-2

⇒2c=16-2

⇒ 2c=14

c=7

Help please!!!! Asap!! math whizzes!!!
Katyanochek1 [597]

Answer:

5xy^3 \sqrt{3x}

Step-by-step explanation:

The radical \sqrt{75x^3y^6} can be simplified by breaking it down into factors and removing the perfect squares from inside the radical.

\sqrt{75x^3y^6} =\sqrt{3*25*x^2*x*y^6} =5xy^3 \sqrt{3x}

25 is a perfect square and is 5 outside the radical.

x^2 is a perfect square and is x outside the radical.

y^6 is a perfect square and is y^3 outside the radical.
