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.

Wind turbines generate electricity by following a simple principle. Moving wind transfers energy to the blades of the windmill, which results in spinning of the blades. These blades are connected to an internal shaft which also starts spinning. This spinning of the shaft generates electricity, which is further distributed to electrical substations to provide electricity to homes and businesses.
<h3>What is a wind turbine?</h3>
Wind turbines work by creating kinetic energy when the power of the wind makes their blades spin. This kinetic energy is converted into electrical energy.
Thus, the steps describing how a wind turbine functions are,
Step 1: Wind moves the blades of the turbine.
Step 2: Internal shaft spins
Step 3: Generator produces electricity
Step 4: Distribution lines carry electricity to substation
