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.

Fossils on continents that are now separated by <u>oceans</u> support the theory of continental drift.
<h3>What is the theory of
continental drift?</h3>
The theory of continental drift was proposed by Alfred Wegener in 1912 and it states that continental landmasses shift position over geologic time on Earth's surface, thereby, appearing to drift together across oceans and into each other.
Thus, the theory of continental drift is supported by Fossils on continents that are now separated by <u>oceans</u>.
Also, we know that continents that are closer to the equator have warmer climates but fossils of <u>tropic plants</u> have been found on islands near the North Pole, thereby, suggesting that islands drifted from the equator.
In conclusion, coal fields in <u>Europe</u> match those that are found in North America, and this supports the theory of continental drift.
