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:

\frac{(x - 5)^2}{625} -\frac{(y - 4)^2}{225} =1

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.

Jack invested $500 in the shares of a company x and $750
-BARSIC- [3]

Assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3

First step is to calculate x return on investment

x return on investment = $600 - $500

x return on investment= $100

Second step is to calculate y return on investment

y return on investment= $900 - $750

y return on investment= $150

Now let determine the ratio of return on investment from company x to that from company y

Using this formula

Ratio of return on investment=x return on investment/y return on investment

Let plug in the formula

Ratio of return on investment=100/150

Ratio of return on investment=2/3

Ratio of return on investment=2:3

Inconclusion assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3
