Answers
Using the distance between two points formula to calculate the side lengths, it is found that the figures are not congruent.
What are congruent figures?Congruent figures are figures that have the same outer side lengths.
We are given the vertices for this problem, hence we use the distance between two points formula to calculate the lengths.
What is the distance between two points?Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
This formula is derived from the Pythagorean Theorem, as the points form a right triangle in the xy-plane, with the hypotenuse being the distance between them.
For Triangle LMK, the side lengths are given as follows:
[tex]LM = \sqrt{(0 - (-6))^2+(-6 - 0)^2} = 6\sqrt{2}[/tex][tex]KM = \sqrt{(-6 - (-6))^2+(-6 - 0)^2} = 6[/tex][tex]LK = \sqrt{(-6 - (-6))^2+(-6 - 0)^2} = 6[/tex]For Triangle XYW, the side lengths are given as follows:
[tex]XY = \sqrt{(8 - 0)^2+(6 - 6)^2} = 8[/tex][tex]WY = \sqrt{(8 - 4)^2+(6 - 2)^2} = 4\sqrt{2}[/tex][tex]XW= \sqrt{(4 - 0)^2+(6 - 2)^2} = 4\sqrt{2}[/tex]Due to different side lengths, the figures are not congruent, and nothing can be stated about the transformations that were used.

Answers
The point (1,1) represents 1+i in the two dimensional complex plane. Absolute value of 1+i = [tex]\sqrt{2}[/tex].
Given the complex number, z = 1+i
The general form of a complex plane is x+iy, where x and y are real numbers.
We can place any complex number into a two-dimensional complex plane with two axes - X and Y.
For z = 1+i, x = 1 and y = 1. So the point (1,1) will represent z = 1+i in the two dimensional complex plane.
The absolute value of a complex number z = x+iy is given by ,

What’s the domain and range?
Answers
Answer:
Domain: x > -4
Range: y > -1
Step-by-step explanation:
Domain is the points on the x axis that could be vaild for that line.
Range is the points on the y axis that could be valid for that line.
The range is: -4 < y < ∞
To find the domain, we need to look at the graph from a left-to-right standpoint (look at the x-axis). When doing so, the furthest point to the left we see is -4. Given that value, we put that as the first value. Then, we can put x since we’re looking at the x-axis. That would leave us with:
-4 < x < ?
Since there is an arrow on the farthest right side, we would put an infinity sign because it goes on forever. The same process is applied to the y-axis, and when doing so, we will get the same answer but with y.

Angle R and angle J are a linear pair. If the measure of R = 3x - 5 and the measure of J = 5x + 1 find the measure of J.
Answers
The measure of angle J is 116°
What are linear pairs of angle?Linear pair of angles are angles formed when two lines intersect at a single point.
Angles are said to be linear if they are adjacent to each other with the intersection of the two lines.
Note that the sum of angles of a linear pair is equal to 180°.
From the information given, we have that;
Angle R = 3x - 5Angle J = 5x + 1But we have the expression as;
Angle R + Angle J = 180°
substitute the values into the equation
3x - 5 + 5x + 1 = 180°
collect like terms
8x - 4 = 180°
8x = 180 + 4
8x = 184
To determine the value of x, divide both sides by the 8
8x/8 = 184/8
Divide through
x = 23
But we have that;
Angle J = 5x + 1
Angle J = 5(23) + 1
Angle J = 115 + 1
Angle J = 116°
Thus, the measure of angle J is 116°

Verify whether x = -1/√3 is a zero of the polynomial 3x²-1.
Answers
Answer:
Below.
Step-by-step explanation:
3x² - 1 = 0
3x² = 1
x² = 1/3
x = ±√(1/3)
= -1/√3, 1/√3.
So, -1/√3 is a zero of 3x² - 1 .
Yes, x = -1/√3 is a zero of the polynomial 3x² - 1 because substituting the value results in zero, confirming its solution to the equation.
To verify whether x = -1/√3 is a zero of the polynomial 3x² - 1, we need to substitute this value into the polynomial and check if it results in zero.
Given polynomial: 3x² - 1
Now, substitute x = -1/√3 into the polynomial:
3(-1/√3)² - 1
Now, simplify:
3(1/3) - 1
1 - 1
The result is zero. Since the expression evaluates to zero when x = -1/√3, this means that x = -1/√3 is indeed a zero of the polynomial 3x² - 1.

how many liters of acid must be added to a 100-liter solution that is 20 percent acid in order to product a solution that is 25 percent acid?
Answers
You can make 106.67 L of 25% v/v acid solution by mixing 6.67 L of pure acid with 100 L of 20% v/v acid solution.
What is an acid?Acids are a type of chemical that can either absorb electrons or give off protons or hydrogen ions. An anion and a cation can form in water when a hydrogen atom that is bonded to an acid releases (dissociates). How acidic a substance is and how acidic its solution pH is depends on how many hydrogen ions it produces.
The word acid stems from the Latin words acidus or acere, which suggest "sour," because one of the characteristics of acids in water is a sour taste (e.g., vinegar or lemon juice).
How thoroughly an acid splits into its ions after being dissolved in water indicates whether it is strong or weak. A strong acid, like hydrochloric acid, completely dissociates into its ions in water.
100 liters * (20/100) = 20 liters acid
Let's assume that the number x represents the amount of pure acid you need to add to your initial solution. The volume of acid will increase by x because you are working with pure acid.
V(acid) = 20 +x
V(solution) = 100+ x
As a result, the percent concentration by volume of the target solution will be equal to
{V(acid)/V(solution)} * 100 = 25%
{(20+x)/(100+x)} * 100 = 25%
(20 +x) 100 = 25(100+x)
2000+100x = 2500 + 25x
75 x = 500
x = 6.67 liters

If 75% of the employees in a company are female and 5% of those female employees are over 6 feet tall what percentage of the company’s employees are both female and over 6 feet tall
Answers
The percentage of the company’s employees are both female and over 6 feet tall is 3.75%
Let the total number of employees in the given company be x. So, the number of female employees in the company are : 75% × x
Number of female employees in company = 0.75x
Now, calculating number of female employees that over 6 feet tall = 0.75x × 5%
The number of female employees that over 6 feet tall = 0.0375x
Percentage of the company’s employees are both female and over 6 feet tall = percentage of female and tall employees ÷ total number of employees × 100
Percentage of the company’s employees are both female and over 6 feet tall = (0.0375x÷x)×100
Percentage of the company’s employees are both female and over 6 feet tall = 3.75%
