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.

Consider the following code segment. String[][] arr = {{"hello,", "hi,", "hey,"}, {"it's", "it is", "it really is"}, {"nice", "g
katrin2010 [14]
"Hi, it is great to get to see you again." would be printed when the code segment is executed.
<h3>The kinds of data type.</h3>
Basically , there are five (5) main recognized data types used in computer programming and these include the following:
- Floating point type (float).
<h3>What is a string?</h3>
A string can be defined as a data type which is commonly used for data values that contain ordered sequences of characters. Also, a string can either contain a single character or be entirely empty.
For instance, "Hello world" is a typical example of a string in computer programming.
Based on the given code segment, "Hi, it is great to get to see you again" would be printed when it is executed by using a compiler.

First, we want to solve for b.
In order to solve for b, we plug in x=6 and f(x)=7 into the equation, since we know f(6)=7
7 = (3/2)(6) + b
7 = 9 + b
Subtract both sides by 9
b = -2
Now, let's insert this value into the equation
f(x) = (3/2)x - 2
Now, plug in x = -2 into the equation to calculate f(-2)
f(-2) = (3/2)(-2) - 2
= -3 -2
= -5
Thus, your answer is A.
Have an awesome day! :)
