I just took the pre-SAT. I thought it was going to be harder than it actually was. When I took it, it took 3 hours. The first part was reading passages and answer questions about it. That was 1 hour. The next part is on grammar. You look at sentences and figure out if they used the right set of words or punctuation. That was 45 min. The 3rd and 4th part was on math. On the third part there was like 12 multiple choice questions and like 4 problems you had to work out. The fourth part had like 21 multiple questions. and 4 problems you had to work out.

Anastasy [175]

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.

vodka [1.7K]

Culture and technology have allowed anatomically modern humans to adapt beyond our biological limits.
Culture is what makes us human, and different from animals. We have developed culture over a long period of time, and even though it changed throughout the ages, it is what defines us nevertheless. And obviously technology is advancing the society to an even greater extent.
