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.

The true statement about white-tailed deer is that they no longer live in an area they were once found; option D.
<h3>What is true of the White-tailed deer of the Puget sound?</h3>
The passage describes two types of Deer found in the area called Puget Sound.
The passage indicates that the white-tailed deer together with the black-tailed deer were the once the two prevalent deer of the Puget Sound.
However, only the black-tailed deer are more common now as the white-tailed deer has been restricted to the low marshy areas and Islands of the Columbia river.
Although the reason for this decline was not given, but it can be inferred that environmental changes led to the decline of the white-tailed deer in the area of Puget sound.
When species of organisms are not able to fully adapt to changes in their environment, the population of that species of organism will reduce until they eventually are no more found in that environment.
In conclusion, white-tailed deer are no longer common in the Puget Sound.
