Answer:
C.<em> BE:KA</em>
Step-by-step explanation:
The segments that have a ratio of lengths 1:2 are <em>BE</em> and <em>KA</em>.
A diameter is a straight line that touches 2 points on the circumference of a circle and touches the point at the center. <em>KA</em> is the diameter.
A radius is a straight line touches a point on the circumference of a circle and touches the point at the center. <em>BE</em> is the radius.
The radius of a circle is half the diameter.

If the radius is 1 cm, then the diameter is 2 cm.
Answer:
y + 4 = a(x - 7)^2
Step-by-step explanation:
The standard vertex form of a parabola with vertex at (h, k) is
y - k = a(x - h)^2
and if we start with the simplest case, y = a(x)^2 and translate its graph 7 units to the right and 4 units down, we get y - {-4] = a(x - 7)^2, or
y + 4 = a(x - 7)^2
