In a video game,a guppy that escapes a net turns into three goldfish.Each goldfish can turn into two betta fish.Each betta fish can turn into two angelfish.Write and evaluate an expression for the number if angelfish that can be formed from one guppy.

The shape of an ellipse is defined by its two focii.

What is Ellipse?

A type of geometric shape that is symmetric and resembles a flattened circle is called Ellipse.

Two fixed points of a shape define focii  which are located on the major axis of the ellipse.

The longest diameter of the ellipse is called Major Axis, and  length of the major axis is equal to distance between the two focii.

The  curvature of the ellipse is determined by the focii of an ellipse.

if focii are further apart, the ellipse will be more circular and  focii are close together, the ellipse will be more elongated.

In addition to the focii, the shape of an ellipse is also determined by a second set of fixed points called vertices, which are located on the minor axis of the ellipse.

Hence,  the shape of an ellipse is defined by its two focii.

Answer: The answer is b i took the test plsss tell me if it helps;)

Answer:

You need to find equation of line containing (1,-3) and (7,15)

First find slope (m) = 15+3)/7-1 = 18/6 = 3

So, eq of line is y +3 = 3( x-1)

y+3 = 3x -3

y-3x +6 = 0
