1. 4x^2-4x-24=0
2. 3p^2-5p-28=0
Answers
4(x^2-x-6) = 0
Next, we can factor the quadratic expression in the parentheses:
4(x-3)(x+2) = 0
This gives us two solutions:
x-3 = 0, so x = 3
x+2 = 0, so x = -2
Therefore, the solutions to the equation 4x^2-4x-24=0 are x=3 and x=-2.
To solve the equation 3p^2-5p-28=0, we can use the quadratic formula:
p = (-b ± sqrt(b^2-4ac)) / 2a
where a = 3, b = -5, and c = -28. Substituting these values, we get:
p = (-(-5) ± sqrt((-5)^2-4(3)(-28))) / 2(3)
Simplifying:
p = (5 ± sqrt(289)) / 6
p = (5 ± 17) / 6
Therefore, the solutions to the equation 3p^2-5p-28=0 are p = 6 and p = -4/3.
1. x = 3 and x = -2.
2. p = 4/3 and p = -7/3.
Step-by-step Explanation:
4x^2-4x-24=0
First, we need to factor out the greatest common factor, which is 4:
4(x^2 - x - 6) = 0
Next, we can factor the quadratic expression inside the parentheses:
4(x - 3)(x + 2) = 0
Now we can use the zero product property, which states that if the product of two factors is 0, then at least one of the factors must be 0. So we set each factor equal to 0 and solve for x:
x - 3 = 0 or x + 2 = 0
x = 3 or x = -2
Therefore, the solutions to the equation 4x^2-4x-24=0 are x = 3 and x = -2.
3p^2-5p-28=0
To solve this quadratic equation, we can use the quadratic formula:
p = (-b ± √(b^2 - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.
In this case, a = 3, b = -5, and c = -28. So we have:
p = (-(-5) ± √((-5)^2 - 4(3)(-28))) / (2(3))
p = (5 ± √(25 + 336)) / 6
p = (5 ± √361) / 6
p = (5 ± 19) / 6
p = 4/3 or p = -7/3
Therefore, the solutions to the equation 3p^2-5p-28=0 are p = 4/3 and p = -7/3.

What is graph?mathematics, a graph is a data structure that represents a collection of vertices (also known as nodes) and edges between them.
A graph can be used to represent a wide range of real-world systems, such as social networks, transportation networks, and electrical circuits.
In a graph, vertices are usually represented as points or circles, and edges are represented as lines or arrows that connect pairs of vertices. Each edge can be directed (pointing from one vertex to another) or undirected (connecting two vertices without any specific direction).
Graphs can be classified in many ways, such as by their density (the ratio of edges to vertices), their connectivity (how many separate components the graph has), and their degree distribution (the distribution of the number of edges connected to each vertex). Graph theory, which is the study of graphs, has many practical applications in computer science, mathematics, and other fields.
Which graph shows the relationship given in the table?
A) graph with the x axis labeled number of days and the y axis labeled total amount of
sunglasses and a line going from the point 0 comma 52 through the point 1 comma 50.
B) graph with the x axis labeled number of days and the y axis labeled total amount of
sunglasses and a line going from the point 0 comma 56 through the point (1,54)
C) graph with the x axis labeled number of days and the y axis labeled total amount of

What is the image point of (-2, 10) after the transformation R270° 0 D₁?
Answers
To find the image point of (-2, 10) under this transformation, we can apply each step of the transformation in turn.
Rotation of 270 degrees counterclockwise about the origin:
The point (-2, 10) will rotate counterclockwise by 270 degrees to a new point. To perform this rotation, we can switch the x and y coordinates of the point, and negate the new x-coordinate. Thus, the rotated point will be (10, 2).
Reflection in the x-axis:
The point (10, 2) will reflect across the x-axis. To perform this reflection, we simply negate the y-coordinate of the point. Thus, the reflected point will be (10, -2).
Therefore, the image point of (-2, 10) after the transformation R270° 0 D₁ is (10, -2).

Find the value of $x$ . Two segments start at a point outside the circle intersect the circle at two points that divide the segments. The length of the first segment is 45 units and length of the segment outside the circle is labeled x. The length of second segment is 50 units and length of the segment outside the circle is 27 units. $x\ =\ $
Answers
The value of x is 29.5 units. Since the segments inside the circle have the same length, we can set 52.5 - x = 23 and get the value of x.
What is radius?It is half of the diameter of the circle. The radius is used to calculate the area of a circle and the length of an arc or a circular sector.
In order to find the value of x, we need to first determine the radius of the circle.
In this problem, the first shorter side is 45 units, and the second shorter side is 27 units. Thus, we can find the radius of the circle by using the following method,
Radius of the circle = √(45² + 27²)
= √(2754) = 52.5 units
Now that we know the radius of the circle, we can use this information to find the value of x. We know that the total length of the first segment is 52.5 units. This means that the length of the segment outside the circle is x units and the length of the segment inside the circle is 52.5 - x units.
Similarly, the total length of the second segment is 50 units, so the length of the segment outside the circle is 27 units and the length of the segment inside the circle is
50 - 27 = 23 units.
Since the segments inside the circle have the same length, we can set 52.5 - x = 23 and solve for x.
52.5 - x = 23
x = 52.5 - 23
x = 29.5 units
Therefore, the value of x is 29.5 units.

Increasing [tex]\frac{15}{16}[/tex] by [tex]\frac{3}{4}[/tex] of it and then increasing the result by [tex]\frac{3}{5}[/tex] of it gives us the fraction of [tex]\frac{45}{32}[/tex].
To increase [tex]\frac{15}{16}[/tex] by [tex]\frac{3}{4}[/tex] of it, we can multiply [tex]\frac{15}{16}[/tex] by [tex]\frac{3}{4}[/tex], which gives us:
[tex]\frac{15}{16}[/tex] × [tex]\frac{3}{4}[/tex] = [tex]\frac{45}{64}[/tex]
Adding this result to [tex]\frac{15}{16}[/tex], we get:
[tex]\frac{15}{16}[/tex] + [tex]\frac{45}{64}[/tex] = [tex]\frac{225}{256}[/tex]
Now, to increase this result by [tex]\frac{3}{5}[/tex] of it, we can multiply [tex]\frac{225}{256}[/tex] by 3/5, which gives us:
[tex]\frac{225}{256}[/tex] × [tex]\frac{3}{5}[/tex] = [tex]\frac{135}{256}[/tex]
Adding this result to [tex]\frac{225}{256}[/tex], we get the final answer:
[tex]\frac{225}{256}[/tex] + [tex]\frac{135}{256}[/tex] = [tex]\frac{360}{256}[/tex]
Simplifying this fraction, we get:
[tex]\frac{360}{256}[/tex] = [tex]\frac{45}{32}[/tex]
The problem involves increasing a fraction by a certain percentage twice. To solve the problem, we first find the increase in the fraction by multiplying it with the given percentage. We then add the result to the original fraction to get the new fraction. This process is repeated for the second increase. Finally, we simplify the resulting fraction if possible. In this specific problem, we are increasing [tex]\frac{15}{16}[/tex] by [tex]\frac{3}{4}[/tex] of it and then increasing the result by [tex]\frac{3}{5}[/tex] of it to find the resulting fraction [tex]\frac{45}{32}[/tex].

b) The 25% value is 240 minutes, and the 75% value is 310 minutes.
c) The value of life in minutes that is exceeded with 95% probability is 357 minutes.
a) To find the probability that the battery lasts more than 4 hours (240 minutes), we first need to convert 240 minutes into a z-score.
z = (X - μ) / σ
z = (240 - 275) / 50
z = -0.7
Now, we'll use a z-table to find the probability that the battery lasts more than 4 hours:
P(Z > -0.7) = 1 - P(Z ≤ -0.7) = 1 - 0.2420 = 0.758
The probability that the battery lasts more than 4 hours is 0.758 (rounded to 3 decimal places).
b) To find the quartiles, we'll use the z-table to find the z-scores corresponding to 25% and 75%:
25%: z = -0.674
75%: z = 0.674
Now, we'll convert the z-scores back into minutes:
Q1 = μ + z * σ = 275 + (-0.674) * 50 = 240 (rounded to the nearest integer)
Q3 = μ + z * σ = 275 + (0.674) * 50 = 310 (rounded to the nearest integer)
The 25% value is 240 minutes, and the 75% value is 310 minutes.
c) To find the value of life in minutes that is exceeded with 95% probability, we first find the z-score corresponding to 95%:
95%: z = 1.645
Now, we'll convert the z-score back into minutes:
X = μ + z * σ = 275 + (1.645) * 50 = 357 (rounded to the nearest integer).

Reflect triangle ABC over the line y = 2. Translate the image by the directed line segment from (0,0) to (3,2). What are the coordinates of the vertices in the final image?
Answers
The coordinates of the triangle's image in the question serve as an example of transformation and are A(-2,4), B (-3,7), and C (0,6).
The triangle's coordinates are as follows:
(-6,-1), (-5,2) and (-3,0) (-3,0)
The new points are created when the triangle is mirrored over the line y = 2.
(-6,5), (-5,2) and (-3,4) (-3,4)
Then, we use the translation to translate the triangle's picture.
(x,y) -> (x + 3, y +2)
We thus have:
(-6,5) => (-6 + 3, 5 + 2) = (-3,7) (-3,7)
(-5,2) => (-5 + 3, 2 + 2) = (-2,4) (-2,4)
(-3,4) => (-3 + 3, 4 + 2) = (0,6) (0,6)
Hence, the triangle's image's coordinates are A(-2,4), B (-3,7), and C (0,6) respectively.

an article marked at rs.8,000 is sold at rs6689.60 allowing some discount and adding vat.8f the rate of discount was double then the rate of vat, find the selling price of the article without vat
Answers
The selling price of the article without VAT is Rs. 6,429.13.
What is Algebraic expression ?
In mathematics, an algebraic expression is a combination of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, and division, that represents a quantity or a relationship between quantities.
Let's assume the rate of discount to be 'x' and the rate of VAT to be 'y'.
According to the problem, the marked price of the article is Rs. 8,000.
After applying the discount, the selling price becomes:
Selling price = Marked price - Discount
Selling price = 8000 - (x÷100) * 8000
Now, we add the VAT to the selling price:
Selling price with VAT = Selling price + (y÷100) * Selling price
Selling price with VAT = [8000 - (x÷100) * 8000] + [(y÷100) * (8000 - (x÷100) * 8000)]
Selling price with VAT = 6689.60 (Given)
We are also given that the rate of discount was double the rate of VAT, i.e.,
x = 2y
Substituting this value in the above equation, we get:
6689.60 = [8000 - (2y÷100) * 8000] + [(y÷100) * (8000 - (2y÷100) * 8000)]
Simplifying this equation, we get:
6689.60 = 8000 * [1 - (2y÷100) + (y÷100) - (2y÷100) * (y÷100)]
6689.60 = 8000 * [1 - (3y÷50) + (y*y÷5000)]
Solving for y, we get:
y = 4
Now, we can calculate the selling price without VAT as follows:
Selling price without VAT = Selling price - (y÷100) * Selling price
Selling price without VAT = 6689.60 - (4÷100) * 6689.60
Selling price without VAT = Rs. 6,429.13
Therefore, the selling price of the article without VAT is Rs. 6,429.13.

For the circle with equation (x-2)^2 + (y+3)^2 = 9, what is the radius?
Answers
Answer:
The equation of the given circle is (x-2)^2 + (y+3)^2 = 9, which is in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.
Comparing the given equation with the standard form, we can see that the center of the circle is (2, -3) and the radius is 3.
Therefore, the radius of the circle is 3 units.
