The slope of the line whose equation is 5x - 3y = 4 is 4/5 5/3 -3/5
The slope of the relation with the equation 5x - 3y = 4 is 5/3
Calculating the slope of the relationTo find the slope of the line whose equation is 5x - 3y = 4, we need to rearrange the equation to be in slope-intercept form, y = mx + b, where m is the slope of the line.
First, we'll subtract 5x from both sides:
-3y = -5x + 4
Next, we'll divide both sides by -3 to isolate y:
y = (5/3)x - 4/3
Now we can see that the slope of the line is 5/3.
So the correct answer is: 5/3

Find the length of the third side. if necessary, round to the nearest tenth of 1 and 3
Using the Pythagorean theorem we know that the third side is 15 units.
What is the Pythagorean theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.
The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a² + b², are equal to the squares on the legs.
To determine c, use the Pythagorean Theorem as follows:
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c
c² = 225
c = √(225)
c = 15

The total power being emitted by the source, given the radiant flux density, is 28,274.3 watts of power.
How to find the total power emitted ?The inverse square law can be used with the formula :
I = P / ( 4 π r ²)
We are given the radiant flux density I = 90 W/m² and the distance r = 5 m.
The power being emitted is therefore :
P = 90 W/ m ² x (4 π ( 5 m) ² )
P = 90 W / m ² x ( 4 π x 25 m ² )

Using the discriminant
Answer:
n = 20/3
Step-by-step explanation:
Theory about the discriminant, and how solutions are acquired via the quadratic formula
One variable quadratic equations in the form [tex]0=ax^2+bx+c[/tex] have exactly one solution when the discriminant [tex](b^2-4ac)=0[/tex].
This is because for quadratic equations of the original form, the two solutions are given by the quadratic formula:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
which is equivalent to [tex]x=\dfrac{-b}{2a}\pm \dfrac{\sqrt{b^2-4ac}}{2a}[/tex].
The [tex]x=\dfrac{-b}{2a}[/tex] is the axis of symmetry, and the [tex]\dfrac{\sqrt{b^2-4ac}}{2a}[/tex] part is how much the solutions deviate from the axis of symmetry. If the deviation is zero, then the two solutions are both ON the axis of symmetry, and are the same number, giving exactly one solution.
Addressing the given equation
Putting it into standard form
Given the given equation...
[tex](n-4)u^2+6=8u[/tex]
subtract 8u from both sides to obtain an equation that looks like the standard form equal to zero...
[tex](n-4)u^2-8u+6=0[/tex]
The variable here is "u" instead of "x", so the solutions to this equation would be [tex]u=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex], where [tex]a=n-4[/tex], [tex]b=-8[/tex], and [tex]c=6[/tex].
Identifying the discriminant
The discriminant then, with values of a, b, and c, substituted, becomes:
[tex]Discriminant=(-8)^2-4(6)(n-4)[/tex]
If we want the discriminant to equal zero (so that there is exactly one solution for "u"), substitute zero on the left side of the equation, and solve for n.
Solving for n
[tex]0=(-8)^2-4(6)(n-4)[/tex]
[tex]0=64-4(6)(n-4)[/tex]
[tex]0=64-24(n-4)[/tex]
Add -24(n-4) to both sides...
[tex]24(n-4)=64[/tex]
Divide both sides by 24...
[tex]n-4=\dfrac{64}{24}[/tex]
Reduce the right hand side...
[tex]n-4=\dfrac{8}{3}[/tex]
Add 4 to both sides...
[tex]n=\dfrac{8}{3}+4[/tex]
Find a common denominator...
[tex]n=\dfrac{8}{3}+\dfrac{12}{3}[/tex]
Find a common denominator...
[tex]n=\dfrac{20}{3}[/tex]
So, if [tex]n=\dfrac{20}{3}[/tex], then the equation [tex](n-4)u^2+6=8u[/tex] has exactly one solution. Furthermore, this is the only value of "n" for which the equation has exactly one solution, because it is the only value of "n" for which the discriminant is zero.

One factor of this polynomial is (x + 8).
2) + 522 - 11x + 104
Use synthetic division to find the other factor of the polynomial.
Answer:
We can use synthetic division to divide the polynomial 2x^3 + 522x^2 - 11x + 104 by x + 8, since x + 8 is a factor of the polynomial:
-8 | 2 522 -11 104
| -16 -412 2584
|--------------------
2 506 -423 2688
The numbers in the bottom row of the synthetic division represent the coefficients of the quotient polynomial, in order of decreasing degree. So the quotient polynomial is:
2x^2 + 506x - 423
Therefore, the other factor of the polynomial is 2x^2 + 506x - 423.

She got extra credit on her project with a score of 29 out of 25 possible points, and she had perfect attendance to class. Compute Tasheena's grade percentage in the class so far.
Tasheena's grade percentage in the class so far is approximately 71.00935%.
How do you find percentages?The percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
To compute Tasheena's grade percentage in the class so far, we can calculate the weighted average of her scores based on the weightage of each component of the final grade.
Given:
Quizzes: 15% weightage
Exams: 55% weightage
Projects: 25% weightage
Attendance: 5% weightage
Tasheena's scores:
Quizzes: 117 out of 150 points
Exams: 74, 86, and 91 on the first three exams (each worth 100 points)
Projects: 29 out of 25 possible points
Attendance: Perfect attendance
Let's calculate Tasheena's grade percentage:
Quizzes:
Tasheena's quiz score percentage = (117 / 150) * 100 = 78%
Exams:
Tasheena's exam average = (74 + 86 + 91) / 3 = 83.67
Tasheena's exam score percentage = (83.67 / 100) * 55 = 46.017%
Projects:
Tasheena's project score percentage = (29 / 25) * 100 = 116%
Attendance:
Tasheena's attendance score percentage = 100% (since she had perfect attendance)
Now, let's calculate the weighted average of Tasheena's scores:
Weighted average = (Quizzes weightage * Quiz score percentage) + (Exams weightage * Exam score percentage) + (Projects weightage * Project score percentage) + (Attendance weightage * Attendance score percentage)
= (15% * 78%) + (55% * 46.017%) + (25% * 116%) + (5% * 100%)
= 11.7% + 25.30935% + 29% + 5%
= 71.00935%
Hence, Tasheena's grade percentage in the class so far is approximately 71.00935%.

What are the coordinates of point S’?
Therefore, the coordinates of [tex]S'[/tex] are [tex](-2, -1)[/tex] .
What are coordinates?A series of numbers called coordinates is used to describe a point's location in a two- or three-dimensional space.
Typically, coordinates in a two-dimensional space are expressed as a pair of integers (x, y), where x denotes the point's horizontal location (also known as the abscissa) and y denotes its vertical position (also known as the ordinate).
Coordinates are commonly expressed as a triplet of numbers (x, y, z) in a three-dimensional space, where x, y, and z stand for the locations along the x, y, and z axes, respectively.
In order to describe the location of objects or points in space, coordinates are often employed in a variety of disciplines, including mathematics, physics, engineering, and computer graphics.
To rotate a point 180° about the origin, we need to negate the x-coordinate and the y-coordinate of the point.
So to find the coordinates of S', we can apply this rule to the coordinates of S:
x-coordinate of [tex]S' = -x-[/tex] coordinate of [tex]S = -(2) = -2[/tex]
y-coordinate of [tex]S' = -y-[/tex] coordinate of [tex]S = -(1) = -1[/tex]
Therefore, the coordinates of S' are [tex](-2, -1).[/tex]
