Find the value of x in the triangle shown below.
Using the Pythagorean Theorem 2 4 X
Answer: We are given a right triangle where the two legs have lengths 2 and 4, and we need to find the length of the hypotenuse (which is denoted by x in the question). We can use the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. That is,
hypotenuse^2 = leg1^2 + leg2^2
Plugging in the values we know, we get:
x^2 = 2^2 + 4^2
Simplifying the right-hand side, we get:
x^2 = 4 + 16
x^2 = 20
Taking the square root of both sides (and noting that x must be positive since it is a length), we get:
x = sqrt(20) = 2sqrt(5)
Therefore, the length of the hypotenuse is 2sqrt(5).

Members of a softball team raised $2252.25 to go to a tournament. They rented a bus for $1018.50 and budgeted $58.75 per player for meals.
Answer: 2252.25 - 1018.50 = P58.75
Step-by-step explanation:
Let S = {4, 9, 14, 19, 24, 29}, E = {9, 19, 29}, F = {4, 14, 24}, and G = {24, 29}. (Enter ∅ for the empty set.) Find the event (E ∩ F ∩ G)c.
Answer: Recall that E ∩ F ∩ G denotes the intersection of the three sets E, F, and G, and the superscript "c" denotes the complement of this set (i.e., everything outside of this intersection).
First, let's find E ∩ F ∩ G:
E ∩ F ∩ G = {24, 29}
Now, let's find the complement of this set:
(E ∩ F ∩ G)c = S - {24, 29}
This means that we take the set S and remove the elements 24 and 29.
So,

C-The upper half of Sample A's data is closer to the value 10 than the upper half of Sample B's data.
D-The data in Sample B is clustered around the center where Sample A is more spread out
The statement that is most likely true is: "The data in Sample B is clustered around the center where Sample A is more spread out."
What is data set?A dataset is a collection of information, often represented in a tabular form, that contains one or more variables or pieces of data for a particular set of individuals or observations. Each individual or observation in the dataset is typically represented by a row in the table, while the variables are represented by columns. Datasets can be used to study a wide variety of phenomena, from social and economic trends to scientific experiments and medical studies. They can be collected through a variety of methods, including surveys, experiments, observations, and automated data collection systems, and can be analyzed using statistical methods to gain insights into the underlying patterns and relationships in the data.
Here,
This is because Sample A has a larger range than Sample B, indicating that the data points in Sample A are more spread out across the number line. Additionally, the median for both samples is the same (5), but the mean for Sample A is higher than the mean for Sample B, which could suggest that there are some larger values pulling the mean upward in Sample A. Taken together, these characteristics suggest that Sample A has more variability in its data points, while Sample B is more clustered around the center.

What are Factors?
Factors are numbers or algebraic expressions that can be multiplied together to obtain a given product.
In algebra, factors are often used to factorize polynomials or other expressions, which involves expressing them as a product of simpler expressions.
One way to determine the factors of x³ + 11x² - 3x - 33 by grouping is:
x²(x + 11) - 3(x + 11)
We can see that the two terms have a common factor of (x + 11), so we can factor it out as follows:
= x³ + 11x² - 3x - 33
=x²(x + 11) -3(x +11)
= (x² - 3) (x+11).
The quadratic factor can be factored further using the difference of squares formula:
(x + 11)(x - √3)(x + √3)
So the factors of x³ + 11x² - 3x - 33 are (x + 11)(x - √3)(x + √3).

Find m1 if m5 = 142 and m4 = 65
The angles measures are m∠1 is 103, m∠2 is 38, m∠3 is 77.
Describe Angles?In geometry, an angle is a measure of the amount of turn between two lines or line segments that meet at a common endpoint, called the vertex of the angle. Angles are measured in degrees or radians.
A degree is a unit of measure for angles, where one full circle contains 360 degrees. A right angle, which forms a quarter of a circle, is 90 degrees. Angles that are smaller than a right angle are called acute angles, while angles that are larger than a right angle are called obtuse angles. Angles that add up to a straight line, which forms half of a circle, are called supplementary angles, while angles that add up to a full circle are called explementary angles.
A radian is another unit of measure for angles, where one full circle contains 2π radians. A right angle, which forms a quarter of a circle, is π/2 radians.
Here, m∠5 + m∠2 = 180 [ Supplementary Angles ]
142 + m∠2 = 180
m∠2 = 180 - 142 = 38
Now, m∠2 + m∠3 + m∠4 = 180 [ Angles in a Triangle ]
38 + m∠3 + 65 = 180
m∠3 = 180 - 103
m∠3 = 77

===================================================
Explanation:
The short leg is y because it is opposite the 30 degree angle.
The connection between the long leg and short leg is through this formula
[tex]\text{long leg} = (\text{short leg})*\sqrt{3}[/tex]
which applies to 30-60-90 triangles only.
Let's use that template to solve for y.
[tex]\text{long leg} = (\text{short leg})*\sqrt{3}\\\\20 = y\sqrt{3}\\\\y = \frac{20}{\sqrt{3}}\\\\y = \frac{20\sqrt{3}}{\sqrt{3}\sqrt{3}}\\\\y = \frac{20\sqrt{3}}{\sqrt{3*3}}\\\\y = \frac{20\sqrt{3}}{\sqrt{9}}\\\\y = \frac{20\sqrt{3}}{3}\\\\[/tex]
Then to find the hypotenuse x, we double the short leg.
[tex]x = 2y\\\\x = 2*\frac{20\sqrt{3}}{3}\\\\x = \frac{2*20\sqrt{3}}{3}\\\\x = \frac{40\sqrt{3}}{3}\\\\[/tex]
This formula works for 30-60-90 triangles only.

Answer:
x = 23.09 (2 d.p.)
y = 11.55 (2 d.p.)
Step-by-step explanation:
The interior angles of a triangle sum to 180°. Therefore, from inspection of the given diagram, the interior angles of the given right triangle are:
30°, 60° and 90°.This means the triangle is a special right triangle and that the 30-60-90 theorem can be applied to quickly find the measures of the missing sides.
What is a 30-60-90 triangle?A 30-60-90 triangle is a special right triangle where the measures of its sides are in the ratio 1 : √3 : 2.
Therefore, the formula for the ratio of the sides is b : b√3 : 2b where:
b = the shortest side opposite the 30° angle.b√3 = the side opposite the 60° angle.2b = the longest side (hypotenuse) opposite the right angle.From inspection of the given triangle, the side opposite the 60° angle is 20. Therefore:
[tex]\implies b\sqrt{3}=20[/tex]
[tex]\implies b=\dfrac{20}{\sqrt{3}}[/tex]
[tex]\implies b=\dfrac{20\sqrt{3}}{3}[/tex]
Substitute the found value of b into the expressions for the other two sides to find the values of x and y.
x is the side opposite the right angle. Therefore:
[tex]\implies x=2b[/tex]
[tex]\implies x=2\cdot \dfrac{20\sqrt{3}}{3}[/tex]
[tex]\implies x=\dfrac{40\sqrt{3}}{3}[/tex]

21. Brian took out a 48-month (4 years) loan for $1,800 at
an annual interest rate of 12%. Andy took out a
2-year loan for $4,200 at an annual interest rate of
10%. Who paid more in interest and how much more
did he pay?
A. Andy paid $34 more in interest.
B. Brian paid $34 more in interest.
C. Andy paid $24 more in interest.
D .Brian paid $24 more in interest.
Answer:
To find the total interest paid by Brian, we can use the simple interest formula:
I = P * r * t
where I is the interest, P is the principal (the amount borrowed), r is the annual interest rate as a decimal, and t is the time period in years.
For Brian's loan, we have:
I = 1800 * 0.12 * 4 = $864
So Brian paid a total of $864 in interest over the 4-year term.
For Andy's loan, we can use the same formula:
I = 4200 * 0.10 * 2 = $840
So Andy paid a total of $840 in interest over the 2-year term.
To find the difference in interest paid, we subtract the smaller amount from the larger amount:
864 - 840 = $24
Therefore, Brian paid $24 more in interest than Andy. The answer is option D.
Answer: the answer is C. Brian paid $24 more in interest than Andy.
Step-by-step explanation: To find out how much interest each person paid, we can use the formula:
Interest = Principal x Rate x Time
where Principal is the amount borrowed, Rate is the annual interest rate (as a decimal), and Time is the length of the loan (in years).
For Brian's loan:
Principal = $1,800
Rate = 0.12
Time = 4 years
Interest = $1,800 x 0.12 x 4 = $864
For Andy's loan:
Principal = $4,200
Rate = 0.10
Time = 2 years
Interest = $4,200 x 0.10 x 2 = $840
So Andy paid $840 in interest, while Brian paid $864 in interest. To find out how much more Brian paid than Andy, we can subtract:
$864 - $840 = $24
Find the median of the set: 200,125,150,225,150,175,150,250,175
Answer:
175
Step-by-step explanation:
To find the median of a set of numbers, we must first arrange them numerically.
Arranging the given set in ascending order, we get:
125, 150, 150, 150, 175, 175, 200, 225, 250
The median is the middle number when the set is ordered this way. If the set has an odd number of values, the median is the middle value. If the set has an even number of values, the median is the average of the two middle values.
In this case, the set has nine values, so it is odd. The middle value is the fifth number, which is 175. Therefore, the median of the set is 175.

What's the lateral and the total surface area
The lateral surface area is 84 square centimeters and the total surface area is 96 square centimeters. The solution has been obtained by using the triangular prism.
What is a triangular prism?
A pentahedron with nine different nets, the triangular prism. Through their three rectangular sides, the bases' vertices and edges are connected. The rectangular sides of the triangular prism are joined side by side to one another. A triangle is represented by any cross-section that is parallel to the base faces.
We know that lateral surface area of prism is given by
A = (a + b + c) * h
Here, we are given
a = 4
b = 3
c = 5
h = 7
On substituting this, we get
⇒ A = (4 + 3 + 5) * 7
⇒ A = (12) * 7
⇒ A = 84 square centimeters
The formula for total surface area is
A = 2 * (area of base) + lateral surface area
Area of base = 0.5 * 3 * 4
Area of base = 6 square centimeters
So, we get
⇒ Total surface area = 2 * 6 + 84
⇒ Total surface area = 12 + 84
⇒ Total surface area = 96 square centimeters
Hence, the lateral and total surface area of the prism are obtained.

Trig Identities---
1. Use the pythagorean identity
Find cotθ if cosθ = 1/7 and the value exists in the first quadrant.
I have a calculus exam tomorrow and have no idea how to solve this equation, please provide a detailed explanation. I'm slow.
Answer:
Let's first recall the Pythagorean identity:
sin²θ + cos²θ = 1
We can use this identity to find the value of sinθ, given that cosθ = 1/7 and θ is in the first quadrant. Since θ is in the first quadrant, both sinθ and cosθ are positive.
cosθ = 1/7
cos²θ = (1/7)² = 1/49
sin²θ + cos²θ = 1
sin²θ + 1/49 = 1
sin²θ = 1 - 1/49 = 48/49
sinθ = √(48/49) = (4/7)√3
Now we can use the definition of cotangent to find cotθ:
cotθ = cosθ/sinθ
Substituting the values we found for cosθ and sinθ, we get:
cotθ = (1/7)/[(4/7)√3] = √3/4
Therefore, cotθ = √3/4 when cosθ = 1/7 and θ is in the first quadrant.

7.Almost" latest release DVDs and Video Games are on special at RetraVision. Todd buys two Games and three DVDs at a total cost of $148.85. His more extravagant friend buys three Games and 5 DVDs for a total of $230.75. Determine the sale price of each DVD and Video Game
Answer:
let video game be x
let DVDs be y
2x+3y=148.85
3x +5y=230.75
make x the subject of the formula
x=148.85-3y/2
3(148.85-3y/2)+5y =230.75
446.55-3y/2=230.75
461.5=446.55-3y
461.5-446.55 =-3y
-3y = 14.95
y=-4.987
x=
