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 element must be in the fifth, sixth, or seventh energy shells.
Explanation:
Because the first ionization energy is less than calcium's, the element must be larger and in the next energy shell. Calcium is in the fourth energy shell, so the element must be in the fifth, sixth, or seventh energy shells.

The President would be responsible for appointing committees including acting with them as an ex-officio, non-voting member.
The work of committees includes monitoring ongoing government operations, identifying issues that call for legislative investigation, gathering and analyzing data, and recommending to the Senate a plan of action.
The chief duty of the President would be to preside over the house. The President would be in charge of maintaining order and also applying but also interpreting the practices as well as procedures of the house using standard procedures, precedents, decisions created by various presidents, as well as other procedural authorities.
The term "president" is used to describe the leader of the country in most republics. The president of such a nation generally performs the roles of the nation's ceremonial head of state, head of its executive branch, and chief moral authority.
