Triangle LMK has vertices L(-6, 0), M(0, -6), and K(-6, -6) and triangle XYW has vertices X(0, 6), Y(8, 6), and W(4, 2). Using the definition of congruence, decide whether the two triangles are congruent. Explain your answer. Give coordinate notation for the transformations you use.
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.

an isosceles triangle has an angle that measures 40 what measures are possible for the other two angles
Answers
The measures are possible for the other two angles are 70 degrees respectively
Isosceles triangleAn isosceles triangle is a triangle that has 2 of its sides and angles to be equal.
Let the measure of the other possible angles be x and y such that x = y
Since the sum of angle in a triangle is 180 degrees, hence;
x+y +40 = 180
x+x+40=180
2x+40=180
2x=180-40
2x = 140
x = 70
x = y = 70 degrees
Hence the measures are possible for the other two angles are 70 degrees respectively

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

The answer is expressed in terms of unit vectors x^ and y^ as B = B (cos θ x ^ + sin θ y ^)
For expressing the magnetic field B in terms of vectors we need to know the magnitude of the magnetic field and the angle between them.
the angle we have is with respect to the positive side of the x-axis, let's use trigonometry.

On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 0.44)
On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)
On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 2. It crosses the y-axis at (0, 3)
Answers
the correct option is:
"On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)"
Which is the graph of the given function?
Here we have the exponential function:
g(x) = (2/3)^x - 2
Now, remember that for any real number different than zero, we have that:
x^0 = 1
So if we evaluate our function in x= 0 we will get:
g(0) = (2/3)^0 - 2 = 1 - 2 = -1
Then the function passes through the point (0, -1)
With this in mind, we conclude that the correct option is:
"On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)"

write the standard form of the equation of the circle with the given characteristics. endpoints of a diameter: (3, 4), (−13, −14)
Answers
The standard equation of the circle will be (x+5)²+(y+5)²= 145
The center of the circle, which is the midpoint between those two locations, may be found first since you know the diameter endpoints.
formula for the midpoint
= ((x1+x2)/2, (y1+y2)/2)
Given points are - (3, 4), (−13, −14)
The circle's center is at (-5,-5)
Therefore, the circle's equation will take the form (x+5)²+(y+5)²=R², where R is the circle's radius.
The distance between a point on the circle and the circle's center in order to get the radius.
Therefore, let's calculate the distance between (-5, -5) and (-13,-14)
Radius R = √((-13+5)²+(-14+5)²) using the distance formula.

What is a sequence of numbers?A sequence is series of objects that follow each other in a particular order.
a. The terms of sequence A are;
1/4, 1/2, 1, 2, 4
Therefore, each term is produced from the previous term by multiplying the previous term by 2 as follows;
1/4 × 2 = 1/2,
1/2 × 2 = 1
1 × 2 = 2
2 × 2 = 4
b. The values in sequence B are;
2, 12, 22, 32, and 42
Therefore, each term is produced from the previous term by adding 10 to the previous term as follows;
2 + 10 = 1212 + 10 = 2222 + 10 = 3232 + 10 = 42c. The definition of the nth term of sequence A is found using the formula for a geometric progression as follows;
nth term of a GP is; A(n) = a•r^(n-1)
Where;
a = The first term = 1/4
r = The common ratio = 1/2/(1/4) = 2
The nth term of sequence A is therefore;
[tex] A(n) = \frac{1}{2} \times 2^{(n-1)} [/tex]d. The definition of the nth term of sequence B is found using the formula for a arithmetic progression as follows;
nth term of a AP is; B(n) = a + (n-1)•d
Where;
a = The first term = 2
d = The common difference = 12 - 2 = 10
The nth term is therefore
B(n) = 2 + (n-1) × 10
e. The value of A(9) is therefore;
[tex] A(9) = \frac{1}{2} \times 2^{(9-1)} = 64 [/tex]
Which gives; A(9) = 64
The value of B(9) = 2 + (9-1) × 10 = 82

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.
