The size and shape of things are preserved by stiff transformations (reflections, translations, and rotations). As a result, archetypes and visuals are always compatible.
What is rigid transformations?The separation between each pair of the geometric object's points is preserved during a rigorous change of the object. In other words, a rigid transformation maintains the object's size and shape. For instance, the rigid transformation of a triangle retains the angles and lengths of the triangle. Imagine a stiff shape distortion, similar to a cardboard shape. The form remains the same after being pushed left and right, rotated, and flipped. When the mold was created using putty, the opposite was true. The thing can then be twisted and stretched. These conversions, nevertheless, are not exact. Stretching a form alters the distances between each pair of its points.

how do you solve this ?
Step-by-step explanation:
first of all, remember for life :
the sum of all angles in a triangle is always 180°.
so, in this right-angled triangle we have therefore
180 = b + 90 + 71
b = 180 - 90 - 71 = 19°
and then regarding a and b :
the sum of all angles around a single point on one side of a line is also always 180°.
why ? because the line can be seen as the extended diameter of a circle, with that point being the center of the circle. and one side of the line is representing half of that circle. and a half-circle is 180°.
so,
a + b = 180
a + 19 = 180
a = 180 - 19 = 161°
FYI, the reason for the first principle (all angles in a triangle are together 180°) is also based on a half-circle concept : any right-angled triangle can be seen as inscribed into a half-circle, with the Hypotenuse (the baseline opposite of the 90° angle) being the diameter of the circle, and the center of the circle being the midpoint of the Hypotenuse.

What does distribution mean in work?
Distribution is the activity of both selling and delivering products and services from manufacturer to customer. This can also be called product distribution. As businesses become more global it becomes important to improve distribution to ensure that customers and all members of the distribution channel are happy.
To obtain the marginal distribution of gender :
Total number of civilians (male + female)
(26393 + 27330) = 53,723
Male :
P(male) = number of male / total
P(male) = 26393 / 53,723 = 0.4912793
P(Female) = number of Female / total
P(Female) = 27330 / 53,723 = 0.5087206

The dot plots show rainfall totals for several spring storms in highland areas and lowland areas.
The dot plots show that the lowland areas experienced significantly more rainfall than the highland area during spring storms, with a larger range and maximum rainfall.
The dot plots show the rainfall totals for several spring storms in both highland and lowland areas. The dots representing the lowland areas are more spread out and have a larger range compared to the dots representing the highland areas. This indicates that the lowland areas experienced more rainfall than the highland areas during these storms. Additionally, the maximum rainfall for the lowland areas is greater than the maximum rainfall for the highland areas, further emphasizing the difference in rainfall between the two areas. This could be due to a number of factors, such as the higher elevation of the highland areas resulting in less moisture being able to accumulate, or the lower temperature of the highland areas resulting in less evaporation and thus less rainfall. Additionally, the lower elevation of the lowland areas could result in more moisture being able to accumulate, and the higher temperature of the lowland areas could result in more evaporation, leading to increased rainfall. Regardless of the cause, the data from the dot plots clearly show that the lowland areas experienced more rainfall than the highland areas during these spring storms.

distribution property
14 - 4[tex]\sqrt{6}[/tex] = (x) - (2[tex]\sqrt{xy}[/tex]) - (2[tex]\sqrt{xy}[/tex]) - (-4[tex]\sqrt{y}[/tex] *[tex]\sqrt{y}[/tex]) ==> simplify
14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) - (-4y)
14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) + 4y ==> subtracting by a negative number is
equivalent to adding by a positive number
14 - 4[tex]\sqrt{6}[/tex] = x + 4y - 4[tex]\sqrt{xy}[/tex] ==> notice any similarities?
x + 4y = 14
[tex]\sqrt{xy}[/tex] = [tex]\sqrt{6}[/tex]
xy=6 ==> solve for x
x = 6/y ==> isolate x by dividing by y on both sides
6/y + 4y = 14 ==> plugin 6/y for x in x + 4y = 14
(6/y + 4y = 14) * y ==> multiply the equation by y to remove fractions
6 + 4y^2 = 14y
4y^2 - 14y + 6 = 14y-14y
4y^2 - 14y + 6 = 0
2y^2 - 7y + 3 = 0 ==> divide both sides by 2 to simplify the equation
2y^2 - 1y - 6y + 3 = 0 ==> -1y - 6y = -7y
y(2y - 1) - 3(2y - 1) = 0 ==> factor the equation
(y - 3)(2y - 1) = 0
y - 3 = 0 ==> y=3
2y - 1 = 0 ==> 2y = 1 ==> y = 1/2
y=3: 3x = 6 ==> plugin 3 for y in xy = 6
x = 2 ==> divide both sides by 3
y=1/2: x/2 = 6 ==> plugin 1/2 for y in xy = 6
x = 12 ==> multiply both sides by 2
When y=3, x=2. When y=1/2, x=12
Hence, the answers are (2, 3) and (12, 1/2).
The expression will be simplified as x + 4y + 4√x√y -14 + 4√6 = 0.

Write a system of equations, graph them, and type the solution.
Answer: 25 weeks
Step-by-step explanation:
Let W represent the number of weeks
Judy equation is
12W + 300
Cassie equation is
20W + 100
Now let's solve it! Our system of equation is
12W + 300 = 20W + 100
Subtract 300 from both sides
12W = 20W -200
Subtract 20W from both sides
-8W = -200
W = 25 weeks
So, it takes 25 weeks for Judy and Cassie to have the same amount saved.
Answer:
let judy = 300 + 12W
cassie = 100 + 20W
300 + 12W = 100 + 20W
300 - 100 = 20W - 12W
200 = 8W
W = 25
CHECKING:
300 + 12(25) = 100 + 20(25)
300 + 300 = 100 + 500
600 = 600
Therefore, it will take 25 days for Judy and Cassie so that they have the same amount saved.

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4, and each adult ticket sells for $8. There was a total of $640 in revenue from the sale of 100 total tickets. Graphically solve a system of equations in order to determine the number of student tickets sold, x, and the number of adult tickets sold, y.
The number of student tickets sold is 40 and the number of adult tickets sold is 60.
Define System of equations
A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given,
Each student ticket sells for = $4
Each adult ticket sells for = $8
Total tickets sale = 100
Revenue from the sale of 100 tickets = $640
Let, x = number of student tickets sold
and, y = number of adult tickets sold
so, let's form a equation
x + y = 100 ------(i)
4x + 8y = 640 -------(ii)
Rewrite eq(i),
x = 100 - y
Now, substitute x value in eq(ii)
4(100- y) + 8y = 640
400 - 4y + 8y = 640
4y = 640 - 400
y = 240 / 4
y = 60
Now, put y value in eq(i)
x + 60 = 100
x = 40
Hence, the number of student tickets sold is 40 and the number of adult tickets sold is 60.
Now, to solve graphically
Let's rewrite the eq(i) and eq(ii)
y = 100 - x
y = 80 - (1/2) x

Since the surface area of A is 4 times the surface area of B, and the volume of B is 125 times the volume of C, we can write the following proportion:
(surface area of A) / (surface area of B) = (volume of B) / (volume of C)
(height of A)^2 / (height of B)^2 = (height of B)^3 / (height of C)^3
We can then cross-multiply and simplify to find the ratio of the heights:
(height of A)^2 / (height of C)^2 = (height of B)^3 / (height of B)^3
(height of A)^2 = (height of C)^2
Therefore, the ratio of the height of A to the height of C is 1:1, or simply 1.
f(x) = x^8e^x f'(x) = f"(x) = Find an equation of the tangent line to y= e^x/x, (1, e).
As per the given function, the equation of tangent line is y - e = e(x -1)
The term tangent line in math referred as a function y=f(x) can be calculate the slope by taking derivative m=f′(x) then at a given point (x1,y1) equation of tangent line is given by the formula y−y1=m(x−x1)
Here we have given the expression y = eˣ/x
Now, we have to calculate the tangent line for the given function,
Let us consider, Slope of the tangent line is written as,
=> m = dy/dx
Now, we have written it as,
=> dy/dx = eˣ/x
then the equation is equate with the slope, then we get,
=> m = eˣ/x
When we put the value of x as 1, then we get
=> m = e
Here we know that the point value is (1, e)
Therefore, the equation of the tangent line is written as,
=> y - e = e(x -1)

*URGENT NEED TO PASS FOR GRADUATION*
built for the 1976 olympic games in montreal canada, the tower is 156 meters tall, measured vertically from the ground to the top. the tower makes a 45 degree angle with the ground. if you were to climb to the top and then accidentally drop your keys, where would you start looking for them?
Answer:
156 meters from the bottom of the tower--------------------------------
The height of the tower is the leg of the isosceles right triangle, since one of angles is 45 degrees.
The horizontal distance from the to the point where you dropped your keys is same as the vertical distance, 156 meters, because it is the other leg of the triangle.

What are the roots of the quadratic equation x² 5x 6 0?
The two solutions to the equation x² + 5x + 6 = 0 are x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.
To find the roots of a quadratic equation, we need to set the equation equal to 0 and then solve for x. In this case, we have the equation x² + 5x + 6 = 0. we can use the quadratic formula. The quadratic formula states that the two solutions for x are given by x = (-b ± √(b² - 4ac))/2a. For our equation, this gives us x = (-5 ± √(5² - 4(1)(6)))/2(1). Once we simplify this, we get x = (-5 ± √(-19))/2. Since the square root of a negative number is not real, we can discard this solution. This leaves us with x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.
x = (-5 ± √(5² - 4(1)(6)))/2(1)
= (-5 ± √(-19))/2
= (-5 ± i√19)/2
