The radius of unit circle is <u>1</u>
Answer:for the one with 16 is 28 and the one with 7 is 4
Step-by-step explanation:
13a. The figure has 5 sides and 5 vertices.
13b. None of the sides are congruent, so the figure is not a regular polygon.
13a. The sides are the straight lines and vertices are the points.
13b. It is not regular because regular polygons have congruent sides.
Answer:
The answer to your question is below
Step-by-step explanation:
Data
Center = (0, 0)
Vertex = (13, 0)
Focus = (12, 0)
Process
From the data we know that it is a horizontal ellipse.
1.- Calculate "a", the distance from the center to the vertex.
a = 13
2.- Calculate "c", the distance from the center to the focus
c = 12
3.- Calculate b
Use the Pythagorean theorem to find it
a² = b² + c²
-Solve for b
b² = a² - c²
-Substitution
b² = 13² - 12²
-Simplification
b² = 169 - 144
b² = 25
b = 5
4.- Find the equation of the ellipse
