question 124

Multiple Choice

An equation of a parabola is given. Write the equation of the parabola in standard form, and identify the
vertex and the equation of the directrix.
- $$y ^ { 2 } + 16 x - 4 y + 52 = 0$$

• A) \(( y + 2 ) ^ { 2 } = - 16 ( x - 3 )\)
• vertex: \(( - 3,2 )\); focus: \(( 7,2 )\)
• B) \(( y + 2 ) ^ { 2 } = - 16 ( x - 3 )\)
• vertex: \(( 3 , - 2 )\); focus: \(( 7 , - 2 )\)
• C) \(( y - 2 ) ^ { 2 } = - 16 ( x + 3 )\)
• vertex: \(( - 3,2 )\); focus: \(( - 7,2 )\)
• D) \(( y - 2 ) ^ { 2 } = - 16 ( x + 3 )\)
• vertex: \(( 3 , - 2 )\); focus: \(( - 7 , - 2 )\)

Definitions:

Atrial Fibrillation

A cardiac rhythm disorder characterized by rapid and irregular beating of the atria of the heart.

Sinoatrial (SA) Node

A group of cells located in the right atrium of the heart that acts as the natural pacemaker, initiating the heart's electrical impulses.

Atrioventricular (AV) Node

A component of the cardiac electrical conduction system located between the atria and ventricles that delays the transmission of electrical impulses to allow for proper filling of the ventricles.

Bundle of His

A collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the AV node to the point of the apex of the fascicular branches.
