un cuadrilátero es un polígono con cuatro aristas y cuatro vértices
Los elementos o características de un cuadrilátero son los siguientes:
4 vértices: puntos de intersección de los lados que conforman el cuadrilátero.
4 lados: segmentos que unen los vértices contiguos.
2 diagonales: segmentos cuyos extremos son dos vértices no contiguos.
4 ángulos interiores: el determinado por dos lados contiguos.
4 ángulos exteriores: el determinado por la prolongación de uno de los lados sobre un vértice y el contiguo en el mismo vértice.
Un incentro, centro de la circunferencia inscrita.
La suma de sus ángulos interiores es igual a 360º
Los cuadriláteros se clasifican según el paralelismo de sus lados, sus longitudes y sus ángulos interiores:
Paralelogramo: sus lados opuestos son paralelos.
Cuadrado: todos sus lados son iguales, todos sus ángulos interiores son rectos, sus diagonales son iguales y perpendiculares entre sí, tiene una circunferencia inscritas y otra circunscrita, además todos los cuadrados son semejantes entre sí .
Rombo: todos sus lados son iguales, cada par de ángulos agudos y obtusos son opuestos, sus diagonales son distintas y perpendiculares entre sí, son bisectrices, tiene una circunferencia inscrita.
Rectángulo: sus lados opuestos son iguales dos a dos y los paralelos, todos sus ángulos interiores son rectos, sus dos diagonales son iguales pero no son perpendiculares entre sí y tiene una circunferencia circunscrita.
Romboide: sus lados opuestos son iguales dos a dos, cada par de ángulos agudos y obtusos son opuestos, sus dos diagonales son de distinta longitud y no son perpendiculares entre sí.
Trapecio: En geometría, se llama trapecio a un cuadrilátero que tiene dos lados no consecutivos paralelos llamados bases del trapecio, y el segmento perpendicular entre las dos bases y su propia longitud son llamadas altura del trapecio
Trapezoide: En geometría euclídea plana, un trapezoide es un cuadrilátero convexo sin lados paralelos.

Answer:
The first one is exponential, the second one is linear, and the last one is quadratic.
Step-by-step explanation:
The first one is exponential, because the values are increasing at an increasing rate. In other words, the difference between any consecutive x-values yield a bigger difference.
The second one is linear, because the values are increasing at a constant rate.
The last one is quadratic, because the values decrease, and then increase, which can be represented by a parabola for a quadratic equation.

Consider the following data that represents gas mileages per gallon (mpg) of randomly selected cars of a particular brand.
28 32 23 28 24 36 31 34 25 28 29 23 25
A researcher wants to test whether the average gas mileage of this type of car is different from 30 mpg. Compute the p-value.
Answers
Answer:
The p-value is 0.1228.
Step-by-step explanation:
Before testing the hypothesis, we need to find the sample mean and the standard deviation.
Sample of 13:
The sample mean is the sum of all values divided by 13. Using a calculator, it is: X = 28.15.
The sample standard deviation is the square root of the division of the sum of the differences squared between each value and the mean, by the number of values. Using a calculator, we get s = 4.0162.
A researcher wants to test whether the average gas mileage of this type of car is different from 30 mpg.
At the null hypothesis, we test if the average gas mileage is of 30 mpg, that is:
[tex]H_0: \mu = 30[/tex]
At the alternate hypothesis, we test if the average is different from 30, that is:
[tex]H_1: \mu \neq 30[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
30 is tested at the null hypothesis:
This means that [tex]\mu = 30[/tex]
From the sample:
[tex]X = 28.15, s = 4.0162[/tex].
Value of the test-statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{28.15 - 30}{\frac{4.0162}{\sqrt{13}}}[/tex]
[tex]t = -1.66[/tex]
P-value of the test:
The p-value of the test is the probability that the sample mean differs from 30 by at least |28.15 - 30| = 1.75, which is a two-tailed test with t = -1.66 and 13 - 1 = 12 df.
Using a t-distribution calculator, this p-value is 0.1228.

Answers
Answer:28.4
Step-by-step explanation:
Delta Math
The diameter of the asked hemisphere is 28.38 in.
What is hemisphere?The half of a sphere is called a hemisphere.
Given that, a hemisphere with a volume of 5990 in³
Volume of a hemisphere = 2/3πr³
2/3πr³ = 5990
r³ = 5990x7x3/22x2
r³ = 125790/44

The Coopers own two vehicles, a mini-van and sedan. The following functions represent the resale value of both cars, in thousands of dollars,
after x years.
Mini-Van: f(1) = 32(0.8)*
Sedan: g(t) = 25(0.8)
Write function t that represents the total resale value, in thousands of dollars, of the two vehicles.
Answers
Answer:
[tex]h(x) = 57(0.8)^x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 32(0.8)^x[/tex]
[tex]g(x) = 25(0.8)^x[/tex]
Required
A function that represents the total resale value of the two vehicles
To do this, we simply add up the functions
[tex]h(x) = f(x) + g(x)[/tex]
[tex]h(x) = 32(0.8)^x + 25(0.8)^x[/tex]
Factorize
[tex]h(x) = (32 + 25)(0.8)^x[/tex]
[tex]h(x) = 57(0.8)^x[/tex]

equation of surface area of a cube prism: surface area = 6s*2
the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2
subtitute values: surface area = 5(20)*2

Step-by-step explanation:
The average rate of change from day 2 to day 10 is given by the slope of the line m =
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The number of houses sold on day 2 is P
The number of houses sold on day 10 is Q
Let the first point be P ( 2 , 8 )
Let the second point be Q ( 10 , 2 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - 8 ) / ( 10 - 2 )
Slope m = -6/8
m = -3/4
Therefore , the number of houses sold between day 2 and 10 is -3/4 houses per day
Hence , the slope is m = -3/4 houses per day

Lesley purchased 5 beads at a total cost of 80 cents. The round beads cost 15 cents each, and the oval beads cost 20 each. The equations and graph below can be used to determine the number of each type of bead kesley purchased. Where x represents the number of round beads and y represents the number of oval beads. What are the numbers of round and oval beads Kelsey purchased?
Answers
Answer:
Lesley purchased 1 oval bead and 4 round beands.
Step-by-step explanation:
Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :
5 x 0.20 + 0 x 0.15 = 1
4 x 0.20 + 1 x 0.15 = 0.95
2 x 0.20 + 3 x 0.15 = 0.85
1 x 0.20 + 4 x 0.15 = 0.80
Therefore, Lesley purchased 1 oval bead and 4 round beands.
