Write the equation of the ellipse graphed below.

Step-by-step explanation:

This is a horizontally stretched ellipse.  That means that the horizontal line which is represented by the x-axis is the longer one.  The equation for this type of ellipse is

In an ellipse, the a value is ALWAYS bigger than the b value, and since the x-axis represents the longer axis, the a goes under the x-squared term.  

To solve for the h, the k, the a, and the b, we simply have to do some counting.  The center of the ellipse, the (h, k) our of equation, is sitting at (4, 6).  Put them where they belong in the equation.  The a axis (the horizontal one) is 8 units long, and the b axis (the vertical one) is 4 units long.  Square both of them and put them where they belong in the equation:

There you go!

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
