Answer:
Step-by-step explanation:
4). a). If the diagonals of a parallelogram are congruent, then it must be a RECTANGLE.
b). If the diagonals of a parallelogram are perpendicular, then it must be a SQUARE.
c). If the diagonals of a parallelogram bisect the angles of the parallelogram, then it must be a RHOMBUS.
d). If the diagonals of a parallelogram are perpendicular and congruent, then it must be a SQUARE.
e). If a parallelogram has four congruent sides, then it must be a SQUARE.
5). Given quadrilateral SELF is a rhombus.
a). All sides of a rhombus are equal,
Therefore, ES = EL = 25
b). Diagonals of a rhombus bisects the opposite angles,
Therefore, m∠ELS = m∠FLS
3x - 2 = 2x + 7
3x - 2x = 7 + 2
x = 9
c). Diagonals of the rhombus bisect the opposite angles, and adjacent angles are supplementary.
m∠ELF = 2(m∠ELS) = 2(2y - 9)
m∠LES = 2(m∠LEF) = 2(3y + 9)
And 2(2y - 9) + 2(3y + 9) = 180
(2y - 9) + (3y + 9) = 90
5y = 90
y = 18

[tex]3.8*10^1[/tex]
Step-by-step explanation:
So we'll be using PEMDAS, which is an acronym used to explain order of operations. It stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.
P- Parentheses:
(2x3+4x2+3)+(3x3−(3x−4))
M- Multiplication (within Parentheses):
(6+8+3)+(9−(-12))
A- Addition (within Parentheses):
(6+8+3)+(9−(-12))
17 + 21
A- Addition:
38
Now, we'll take that number and put it in standard form, which is the number with only one number outside of the decimal times ten to the however many times it can be divided by ten.
So,
38/10 = 3.8
So,
3.8 * 10^1 is your answer.

Instructions: Find the measure of the missing angle using the Exterior Angle Sum
Theorem
Answer:
It's an isosceles triangle equal 2 sides so
it will be x+67 ° +67 ° =180° ( sum of angle in triangle)
x+134 °=180 °
x =180 - 134
x = 46 °
The measurement of the missing angles in the given triangle is 67.
Use the concept of isosceles triangle defined as:
A triangle with two equal-length sides is said to be isosceles.
An isosceles triangle has equal angles on either side of its equal sides.
In the given figure,
One angle is 67 degrees
And two sides are equal.
Let the missing angle is x°
Since the two sides of this triangle are equal,
So this is an isosceles triangle.
Then two opposite angles must be equal.
For a triangle,
The sum of interior angles = 180°
Therefore,
67° + 67° + x° = 180°
x° = 46°
Hence,
The measurement of the missing angle is 46°

Ivan sabe que pir su salud debe tomar agua hervida , lleno 3 botellas de agua hervida para empezar los lleno de 7,2 L usando 3 botellas grandes y 5 botellas pequeñas , no lleno otra botella ya que le faltaba 0,5L pero lleno una pequeña mas y le quedaron 0,3L de ahua hervida para tomar ¿Cuanta agua hervida tenia al inicio ivan?
Answer:
Al inicio Iván tenía 8.1 litros de agua hervida.
Step-by-step explanation:
Dado que Iván sabe que por su salud debe tomar agua hervida, y llenó 3 botellas de agua hervida para empezar con 7,2 L usando 3 botellas grandes y 5 botellas pequeñas, y no llenó otra botella ya que le faltaba 0,5L pero llenó una pequeña mas y le quedaron 0,3L de agua hervida para tomar, para determinar cuánta agua hervida tenia al inicio Iván se debe realizar el siguiente cálculo:
Botella grande = -0.5 litros
Botella chica = +0.3 litros
0.5 + 0.3 = 0.8
Así, la diferencia entre una botella grande y una botella chica es de 0.8 litros.
3X + 5(X - 0.8) = 7.2
3X + 5X - 4 = 7.2
8X = 7.2 + 4
X = 11.2 / 8
X = 1.4
3 x 1.4 + 5 x 0.6 = 7.2
7.2 + 0.6 + 0.3 = 8.1
Por lo tanto, al inicio Iván tenía 8.1 litros de agua hervida.

What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
Let the values of x be x = { -4 , -3 , -2 , -1 , 0 }
Let the values of y be y = { -10 , 0 , 0 , -4 , -6 }
Now , the y intercept of the function is when the value of x = 0
So , when x = 0 , the value of y = -6
And , f ( 0 ) = -6
Therefore , the y intercept is ( 0 , -6 )
Hence , the y intercept of the function is ( 0 , -6 )

the shape of a quadratic equation is called a...?
Answer:
If you mean graphing its called a parabola
Step-by-step explanation:
The shape of a quadratic equation is called a Parabola.
The graph of a quadratic equation is a curve known as a parabola. The shape of a parabola can vary depending on the values of "a," "b," and "c" in the quadratic equation.
If "a" is positive, the parabola opens upwards, forming a U-shape.If "a" is negative, the parabola opens downwards, forming an inverted U-shape.The point where the parabola intersects the x-axis is called the vertex. The axis of symmetry is a vertical line passing through the vertex, dividing the parabola into two symmetrical halves.The x-intercepts are the points where the parabola intersects the x-axis. The y-intercept is the point where the parabola intersects the y-axis. It represents the value of the quadratic equation when "x" is equal to zero.Therefore, the shape is parabola.

The predicted value of Y when X = 0. Therefore, option D is the correct answer.
What is Regression analysis?Regression analysis is one of the sophisticated statistical modeling techniques in which we try and establish a relationship between variables, the dependent or response variable, and one or more independent or explanatory variables.
The linear regression equation of a single variable can be written down as: Y=a+bX
According to the definition of the equation of regression analysis, the Y-intercept represents the predicted value of Y when X = 0.
The Y-intercept, as the name suggests, is the point when the regression line crosses the y axis. This happens only when the value of the x variable is zero:
Y-intercept = Y(0)=a+b(0)
Y-intercept=a
Therefore, option D is the correct answer.

Aa dealer bought a laptop for rs 45000 and sold it to retailer again sold it to a customer at 25% profit. how much did the customer pay for the laptop.
Answer:
Rs 56250
Step-by-step explanation:
Given:
Cost price of laptop (CP) = RS 45000
Profit (P) = 24 % = 0.24
The selling price of dealer (SP) = Cost price of customer,
So,
Selling price of dealer = [tex]\tt CP + Profit \:Percentage \:of \:C.P[/tex]
Selling price of dealer = CP(1+ Profit %)
Substituting value
Selling price of dealer = 45000(1+0.24)
Selling price of dealer = 45000*1.24
Selling price of dealer = 56250
Therefore, the Customer paid Rs 56250 for the laptop.
Answer:
Rs 56,250
Step-by-step explanation:
To calculate how much the customer paid for the laptop, we need to determine the total price after the retailer added a 25% profit margin.
If the dealer purchased the laptop for Rs 45,000, then Rs 45,000 is 100%. If the dealer sells it to a customer at 25% profit, it was sold at 125% of its purchase price.
Therefore, to calculate how much the customer paid for the laptop, we need to find 125% of Rs 45,000:
[tex]\begin{aligned}\sf 125\%\;of\;45000&=\sf\dfrac{125}{100} \times 45000\\\\&=\sf\dfrac{125\times 45000}{100} \\\\&=\sf\dfrac{5625000}{100} \\\\&=\sf56250\end{aligned}[/tex]
Therefore, the customer paid Rs 56,250 for the laptop.

W=X+Xyz for z
Answer:
z= (w-x)/ xy
Step-by-step explanation:
w= x+xyz solve for z
w= x+xyz, isolate the term that has z by subtracting x from both sides (because is the opposite of adding x to the term xyz we try to isolate)
w-x = xyz, divide both sides by xy assuming that xy≠0 (because is the opposite of multiplying z by xy to solve for z, and xy≠0 because we do not want to divide by 0)
(w-x)/xy = z

what is the measure of arc MP
Answer:
[tex]m\widehat{MP}=118^{\circ}[/tex]
Step-by-step explanation:
In any circle, the measure of an inscribed angle (an angle created when the intersection of two chords is on the circle) is equal to half of the arc it forms. In this case, [tex]\angle MPN[/tex] is an inscribed angle that forms [tex]\widehat{MN}[/tex]. Therefore, the measure of arc MN must be twice the measure of angle MPN:
[tex]m\widehat{MN}=2\cdot m\angle MPN,\\m\widehat{MN}=2\cdot 31^{\circ}=62^{\circ}[/tex]
Since we want to find the measure of arc MP, we need to know that there are 360 degrees in a circle. Since [tex]\overline{PN}[/tex] is a diameter of the circle (line that has two endpoints on the circle and that passes through the center of the circle), each side of [tex]\overline{PN}[/tex] must be 180 degrees.
Therefore, we have:
[tex]m\widehat{MN}+m\widehat{MP}=180^{\circ},\\62^{\circ}+m\widehat{MP}=180^{\circ},\\m\widehat{MP}=\boxed{118^{\circ}}[/tex]
