part B
Answer:
The endpoints of the latus rectum are
and
.
Step-by-step explanation:
A parabola with vertex at point
and whose axis of symmetry is parallel to the y-axis is defined by the following formula:
(1)
Where:
- Independent variable.
- Dependent variable.
- Distance from vertex to the focus.
,
- Coordinates of the vertex.
The coordinates of the focus are represented by:
(2)
The <em>latus rectum</em> is a line segment parallel to the x-axis which contains the focus. If we know that
,
and
, then the latus rectum is between the following endpoints:
By (2):


By (1):



There are two solutions:




Hence, the endpoints of the latus rectum are
and
.
Water cooler
holds = 50 pt of water
1 L≈1.06 qt (which is the value of US liquid quart)
1.06 qt = 2.12 pt (which is the value of US liquid pint)
So when we are calculating how many liters of water cooler holds,
divide the 50pt with 2.12pt
50pt/2.12pt = 23.6 Liters
<span>So 23.6 is the correct answer.</span>
