The lengths of each side of the triangle LMN are, LM = 4 units, MN = 3.606 units, and NL = 2.236 units.
The lengths of each side of the triangle L'M'N' are, L'M' = 4 units, M'N' = 3.606 units, and N'L' = 2.236 units.
We can conclude that all corresponding sides are equal, and the two triangles are congruent.
All angles must be congruent, as the image L'M'N' has been parallelly translated from the preimage LMN.
The coordinates of the image are L' (-4, 1), M' (-4, 5), and N' (-2, 2). The length of each side of the triangle LMN:
LM = √((2 - 2)² + (-6 - (-2))²),
or, LM = √((0² + (-4)²),
or, LM = √16 = 4 units.
MN = √((2 - 4)² + (-2 - (-5))²),
or, MN = √((-2)² + (3)²),
or, MN = √(4 + 9) = √13 = 3.606 units.
NL = √((4 - 2)² + (-5 - (-6))²),
or, NL = √((2)² + (1)²)
or, NL = √(4 + 1) = √5 units = 2.236 units.
The length of each side of the triangle L'M'N':
L'M' = √((-4 - (-4))² + (5 - 1)²),
or, L'M' = √((0² + (4)²),
or, L'M' = √16 = 4 units.
M'N' = √((-4 - (-2))² + (5 - 2)²),
or, M'N' = √((-2)² + (3)²),
or, M'N' = √(4 + 9) = √13 = 3.606 units.
N'L' = √((-4 - (-2))² + (1 - 2))²),
or, N'L' = √((2)² + (1)²)
or, N'L' = √(4 + 1) = √5 units = 2.236 units.
Now, since LM = L'M', MN = M'N', and NL = N'L', that, is all the corresponding sides are equal, we can conclude that all corresponding sides are equal, and the two triangles are congruent.
Since the triangles are congruent, the image L'M'N' has been parallelly translated from the preimage LMN.
Thus, all angles must be congruent, as the image L'M'N' has been parallelly translated from the preimage LMN.
Every point moves the same amount and in the same direction throughout a translation. As a result of the picture being identical in size and shape to the preimage, a translation is referred to as a rigid transformation or isometry.

A soccer team won only 10 of their first 30 games. How many of their remaining 20 games will they have to win to have a .500 record??
Answer: 5 games
Step-by-step explanation: A .500 record means that the soccer team won half of their games ( that's how I interpret it). Since they are going to play 30 games, they need to win half of 30 or 15 games to have that record. 15-10 = 5. So, they need to win 5 more games to have a .500 record.

When you send out a resume, the probability of being called for an interview is 0. 40. what is the probability that the first interview occurs on the fifth resume that you send out?
The probability that the first interview occurs on the fifth resume that you sent is 0.2592.
According to the given question.
The probability of being called for an interview, p = 0.40.
So, the probability of not being called for an interview, q = 1 - 0.40 = 0.60
As we know that binomial distribution summarizes the number of trials, or observations when each trial has the same probability of attaining one particular value. The binomial distribution determines the probability of observing a specified number of successful outcomes in a specified number of trials.
Therefore, the probability that the first interview occurs on the fifth resume that you send out
= [tex]^{5} C_{1} (0.40)^{1} (0.60)^{4}[/tex]
= 5(0.40)(0.1296)
= 0.2592
Hence, the probability that the first interview occurs on the fifth resume that you sent is 0.2592.

Measure of angle TRV?
Answer:
130 degrees
Step-by-step explanation:
We know (x-10)+(2x+10) is 180 degrees.
So first we need to find x. (x-10)+(2x+10)=3x
3x=180
x=60
Angle TRV is 2x+10.
If we input 60 in the place of x, it is 2(60)+10=120+10=130.

How to find the equation of quadratic regression using a calculator?To find the equation, we need to insert the points (x,y) in the calculator.
In this problem, we have that the function initially increases, then it decreases, which means that it is a quadratic function. The points (x,y) to be inserted into the calculator are given as follows:
(1, 20), (2,17), (3, 16), (4,16), (5,18), (6,21), (7,25), (8,31)
Inserting these points into the calculator, the prediction of y for a value of x is given as follows:
y = 0.702x^2 - 4.726x + 23.857
Hence, when x = 10, the prediction is:

If for the first 150 miles of a trip, an car drives at v mph, for the next 200 miles, the car drives at (v+25) mph and the average speed of the whole trip is 35 mph, then the value of v will be 20mph (A).
Given Information:
Average speed = 35 mph
Total distance = 150 + 200 = 350 miles
For the first 150 miles of a trip, an car drives at v mph speed
⇒ Time, t1 = 150/v hrs
For the next 200 miles, the car drives at (v+25) mph speed
⇒ Time, t1 = 200 / (v+25) hrs
Now, the formula for average speed is given as,
Total distance / Total time
= [tex]\frac{350}{\frac{150}{v}+\frac{200}{(v+25)} }[/tex]
⇒ [tex]\frac{350}{\frac{150}{v}+\frac{200}{(v+25)} }[/tex] = 35 mph
[tex]\frac{350 v (v+25)}{150(v+25) + 200v}[/tex] = 35
[tex]\frac{350v^{2} + 8750v}{150v +3750 + 200v}[/tex] = 35
350v² + 8750v = 35 (350v + 3750)
v² + 25v = 35v + 375
v² - 10v = 375
v² - 10v - 375 = 0
Now, the above equation for speed can be written as,
v² - 20v + 15v - 375 = 0
v(v-20) + 15(v-20) = 0
(v-20) (v+15) = 0
v = 20

[tex]a^{2} +(a^{2} +a^{2} )=24^{2}[/tex]
[tex]a=\sqrt[8]{3} cm[/tex]
The area of the cylinder base=[tex]\pi R^{2}[/tex]
=[tex]\pi (\frac{1}{2} \sqrt[8]{3} )^{2}[/tex]
=[tex]48cm^{2}[/tex]
The high of the cylinder is[tex]\sqrt[8]{3}cm[/tex]
The volume of the cylinder:
=s*h
=[tex]48\pi *\sqrt[8]{3}[/tex]
=[tex]384\pi \sqrt{3} cm^{3}[/tex]
The volume of the cylinder is [tex]384\pi \sqrt{3cm }^{2}[/tex].

The biggest possible volume of the cylinder will be [tex]2089.497\hspace{1mm}\text{cm}^3[/tex].
What will be the diameter and height of the cylinder obtained from a cube and what are the formulas for the diagonal of a cube and the volume of a cylinder?If a cylinder with the biggest possible volume is cut inside the cube, the height of the cylinder and the diameter of the cylinder will be equal to the side length of the cube.For example, consider the following figure in which the cylinder is cut inside of the cube and since the side length of the cube is [tex]x[/tex], the diameter and the height of the cylinder are also [tex]x[/tex]If the side length of a cube is [tex]x[/tex] unit, then its diagonal will be [tex]x\sqrt{3}[/tex] unit.The formula for the volume of a cylinder is [tex]V=\pi r^2h[/tex], where [tex]r[/tex] is the radius and [tex]h[/tex] is the height of the cylinder. If [tex]d[/tex] is the diameter, then [tex]r=\frac{d}{2}[/tex].Now, given that the diagonal of the cube is [tex]24[/tex] cm. So, if the side length of the cube is [tex]x[/tex] cm, then we must have
[tex]x\sqrt{3}=24\\\Longrightarrow x=\frac{24}{\sqrt{3}}\\\Longrightarrow x=8\sqrt{3}[/tex]
Thus, the side length of the cube is [tex]8\sqrt{3}[/tex] cm.
So, the height of the cylinder with maximum volume will be [tex]h=8\sqrt{3}[/tex] cm and the diameter will be [tex]d=8\sqrt{3}[/tex]cm i.e. the radius will be [tex]r=\frac{d}{2}=\frac{8\sqrt{3}}{2}=4\sqrt{3}[/tex] cm.
So, using the above formula for the volume of a cylinder, we get
[tex]V=\pi r^{2}h=\pi\times (4\sqrt{3})^2\times 8\sqrt{3}=2089.497\hspace{1mm}\text{cm}^3[/tex].
Therefore, the biggest possible volume of the cylinder will be [tex]2089.497\hspace{1mm}\text{cm}^3[/tex].

Which of the x values are solutions to the inequality 4(2 – x) > –2x – 3(4x 1)? check all that apply.
The solution for the inequality given exists x > -11/10. The inequality contains an infinite number of solutions as long as it is greater than -11/10.
How to determine the value of x?
Given: 4(2 – x) > –2x – 3(4x + 1)
The inequality can be simplified to
8 - 4x > -14x - 3
subtract 8 from both sides of the equation, and we get
8 - 4x - 8 > -14x - 3 - 8
- 4x > -14x - 11
Add 14x from both sides
- 4x + 14x > -14x - 11 + 14x
10x > - 11
x > - 11/10
The solution for the inequality given exists x > -11/10. This means that any number greater than -11/10 exists as a solution to the inequality given. The inequality contains an infinite number of solutions as long as it is greater than -11/10.

Answer:
y is equal to -16
Answer:
y = 8
Step-by-step explanation:
We can use proportions for this question since y varies directly with x. This means that if x changes, y changes along with the x, and vice versa.
When y = -8, x = 4, so the proportion will be -8 : 4.
We need to find the y when x is 4, so our equation will be:
-8 : 4 = y : -4
Since the proportion will be the same.
Next, we multiply the inner two numbers, and the outer two numbers, saying that the values are the same.
4y = 32
y = 8
So y = 8 will be our answer!
