Answer:
The domain of function 
is set of all real numbers.
Domain: (-∞,∞)
Step-by-step explanation:
Given:
the domain of both the above functions is all real number.
To find domain of :
Substituting functions 
and 
to find
The product can be written as difference of squares. ![[a^2-b^2=(a+b)(a-b)]](https://tex.z-dn.net/?f=%5Ba%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29%5D)
∴ 
The degree of the function is 2 as the exponent of leading term 
is 2. Thus its a quadratic equation.
For any quadratic equation the domain is set of all real numbers.
So Domain of is (-∞,∞)
Using the line of the best fit, the predicted student's score in English test is 48
<h3>How to determine the student's score in English?</h3>
From the question, we have:
Mathematics score = 60
The scores in English tests are plotted on the y-axis.
On the given graph, we have:
(x,y) = (60,48)
This means that when x = 60, the value of y is 48
This in other words means that the student's score in English test is 48

Answer:
16 meters.
Step-by-step explanation:
There are two things to keep in mind at this point, the first is that a square has all its sides equal and the second is that the perimeter in this type of figure is the sum of all the sides.
Knowing the above, we can deduce that therefore each side of the square measures 4 meters and the perimeter could be calculated since we know the value of all the sides, we know that a square has four sides:
p = 4 +4 +4 +4
p = 16
that is to say that the perimeter is equal to 16 meters.
Answer: 1/6
Reason:
There's 1 side labeled "4" out of 6 sides total. So that's where the 1/6 comes from.
The "given that you already rolled a four on the first die" is unneeded info in my opinion, because each die is separate or independent from one another.
