The true statement about the directrix is that each directrix of this ellipse is 31.25 units from the center on the major axis.
<h3>How to determine the distance of the directrix?</h3>
The equation of the ellipse is given as:
The above means that:
a^2 = 625
a = 25
b^2 = 225
b = 15
Calculate c using:
c^2 = a^2 - b^2
This gives
c^2 = 625 - 225
Evaluate the difference
c^2 = 400
Evaluate the square root
c = 20
The equation of the directrix is
x - x₀ = ± a²/c
So, we have:
x - x₀ = ± 625/20
Evaluate the quotient
x - x₀ = ± 31.25
This means that, each directrix is 31.25 units from the center on the major axis.

Answer:
The poultry house must have to be well ventilated.
Ensure sufficient entrance of sunlight and fresh air inside the house.
It would be better if the house become situated north to south faced.
The proper distance of one house to another house is about 40 feet.
Clean the house properly before keeping the birds inside the poultry house.
Make a deep liter and keep it dry and clean always.
Wooden and rice bran can be used for making liter.
Keep feed and feeding equipment in proper distance inside the poultry house according to the number and demand of poultry birds.
The poultry house and all equipment must have to be free from virus, parasites and germs.
Build the poultry house in such a place where all the poultry birds are free from all types of wild animals and other predators.
The poultry housing area will be free from loud sound/sound pollution.
Make the poultry house in quite and calm place.
It would be better if the house located in an open air place.
However, to be successful in poultry farming the producers must have to be aware in making the poultry house. Be sure that all necessary equipment and facilities are available inside the poultry house.

Explanation:
A timeline can be defined as a graphical representation of a series of important events in order in which they have occurred i.e in a chronological or sequential order. Thus, a timeline shows the order of events from top to bottom or left to right, starting with the earliest and moving forward to the most recent (latest).
Generally, a timeline is typically considered to be a cause and effect graphic organizer due to the fact that it illustrates events in a chronological or sequential order, their place in history, and how these events are interrelated or led to another.
This ultimately implies that, timelines show;
a. The order of events.
b. An event’s place in history.
c. Why an event may have taken place.
<em>For example, a timeline can be used to show the order in which the various battles fought during the American Revolutionary War occurred. </em>
