A square has an area of 56 units, find the length of the side in simplest form. Has to be an Improper fraction.
Answers
The length of the side of the square in simplest form is 2sqrt(14).
The area of a square is given by the formula \(A = s^2\), where A is the area and s is the length of a side.
We are given that the area of the square is 56 units, so we can set up the equation:
\(56 = s^2\)
To solve for s, we can take the square root of both sides of the equation:
sqrt(56) = \(sqrt(s^2)\)
We can simplify the square root of 56 by factoring it:
sqrt(56) = sqrt(222*7) = 2sqrt(14)
So, we have:
2sqrt(14) = s
This is an improper fraction because the numerator is larger than the denominator. Therefore, the length of the side of the square in simplest form is 2sqrt(14).

Answers
For a curve to be a density curve, it must meet certain conditions such as it should be non-negative, and the area under the curve should equal 1. Furthermore, the curve should be continuous and smooth, and there should be no values outside the range of the data.
Let's see how the height would need to be for this curve to be a density curve.A density curve is a statistical representation of the distribution of a dataset or population. Density curves are used to describe the distribution of continuous data and provide a visual representation of the likelihood of an event occurring within a specific range of values. It helps to determine the proportion of data that falls within a given range of values. A density curve is used to provide a graphical representation of data without showing the individual data points.To be a density curve, a curve must have the following properties:The curve should be non-negative.The area under the curve should be equal to 1.The curve should be smooth and continuous.There should be no values outside the range of the data.From the above properties, we can conclude that the height required for a curve to be a density curve depends on the data that the curve represents. As long as the curve meets the above conditions, it can be considered a density curve. So, there is no specific height required for a curve to be a density curve. The height of the curve can vary depending on the range of the data and the distribution of the data.For such more question on properties

The grade point average for college students is based on a weighted mean computation. For most colleges, the grades are given the following data values: A (4), B (3), C (2), D (1), and F (0). After 60 credit hours of course work, a student at State University earned 6 credit hours of A, 15 credit hours of B, 31 credit hours of C, and 8 credit hours of D.
a. Compute the student's grade point average. Round your answer to two decimal places.
b. Students at State University must maintain a 2.5 grade point average for their first 60 credit hours of course work in order to be admitted to the business college. Will this student be admitted?
Answers
The student's grade point average is 2.32.
The student will not be admitted to the business college.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
(a)
Total grade points earned
= (6 x 4) + (15 x 3) + (31 x 2) + (8 x 1)
= 24 + 45 + 62 + 8
= 139
Total credit hours.
= 6 + 15 + 31 + 8
= 60
Now,
The student's grade point average:
= Total grade points earned / Total credit hours taken
= 139 / 60
= 2.32
(b)
2.32 < 2.5
This means,
The student's grade point average is lower than the required 2.5 GPA for admission to the business college.
Thus,
The student's grade point average is 2.32.
The student will not be admitted to the business college.

Let f (x) = x4 + x3 + x2 + x + 1 ∈ Z2[x]. Prove that f(x) is irreducible over Z2[x] or not?
Answers
Answer and Step-by-step explanation:
Let f(x) = x4 + x3 + x2 +x + 1 Є Z2[x]. Prove that f(x) is irreducible over Z2[x] or not?
Proof:-
Let f(x) = x4 + x3 + x2+ x+1 Є Z2[X].
Then f (0) = 1 = f(1), so f(x) has no roots, By Factor theorem, which states that polynomial f(x) has a factor(x-a) if and only if f(a)=0. Hence, f(x) has no linear factor. If f(x) is reducible, it must have factors of degree 2 and degree 3. But f(x) has no degree 2 factors.
We know that only irreducible quadratic in Z2[X] is x2 + x +1. When we divide f(x) by x2 + x +1 we get a remainder of 1, so x2 + x +1 is not a factor of f(x) therefore f(x) is irreducible.
Given the points P (3, 5) and Q (-5, 7) on the cartesian plane such that R (x, y) is
the midpoint of PQ, find the equation of the line that passes through R and
perpendicular
to PQ.
Answers
Answer:
-22=22
Step-by-step explanation:
3,5-5,7=
-22/22
The equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.
To find the equation of the line passing through the midpoint R and the points P and Q, we first need to find the coordinates of the midpoint R. The midpoint coordinates can be found by taking the average of the x-coordinates and the average of the y-coordinates of P and Q.
The x-coordinate of the midpoint R is (3 + (-5)) / 2 = -1/2.
The y-coordinate of the midpoint R is (5 + 7) / 2 = 6.
So, the coordinates of the midpoint R are (-1/2, 6).
Next, we can use the two-point form of the equation of a line, which states that the equation of the line passing through points (x₁, y₁) and (x₂, y₂) is given by:
(y - y₁) = (y₂ - y₁) / (x₂ - x₁) \(\times\) (x - x₁)
Substituting the coordinates of R (-1/2, 6) and P (3, 5) into the equation, we have:
(y - 6) = (7 - 5) / (-5 - 3) \(\times\)(x - (-1/2))
Simplifying the equation:
(y - 6) = (2 / -8) \(\times\)(x + 1/2)
(y - 6) = -1/4 \(\times\)(x + 1/2)
4(y - 6) = -x - 1/2
Therefore, the equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.

The slope the given straight line is 5/4.
What is defined as the slope of the straight line?A line's slope is characterised as the transformation in y coordinate with regard to the shift in x coordinate.
The net y coordinate change is Δy, while the net x coordinate change is Δx. So the transformation in y coordinate in connection with the shift in x coordinate is written as, m = Δy/Δx, where,m is the slopetan θ = Δy/Δx; tan θ is the slope of the line.The formula for the slope when the coordinates of the two points are given;
m = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)
Consider two points from the graph;
(x₁, y₁) = (4, 4) and (x₂, y₂) = (0, -1)
Put the values in the slope formula;
m = (y₂ - y₁)/(x₂ - x₁)
m = (-1 - 4)/(0 - 4)
