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 given statement about the identification of poor performers is a challenge that has existed since the earliest days of performance management is TRUE
<h3>What is Performance Management?</h3>
This refers to the corporate management tool that enables managers to track and analyze the work of their employers.
Hence, we can see that the identification of poor performers is a challenge that has existed since the earliest days of performance management and this also shows that the performance management process does not seem to be particularly good at weeding out poor performers.
