128) Los vertices de esta figura son:
(-2,1) (4,1) (4,-2) (0,-3)
129) Siempre se busca primero la coordenada horizontal! esa es la coordenada en "x" . Despues es la coordenada vertical , que es la coordenada en "y" .
Por lo tanto , para el punto de arriba , la coordenada horizontal es 1 y la vertical es 3, por lo tanto la coordenada del punto es (1,3) .
Las coordenadas de los puntos son entonces.
[tex](1,3)\\(3,0)\\(2-2)\\(-1,-2)\\(-2,1)[/tex]
130) Las coordenadas del vertice faltante son (1,-2)
131) Tenemos que representar un hexágono concavo en el plano cartesiano.
Un hexágono concavo es un poligono de 6 lados y 6 ângulos, siendo uno de estos últimos mayor a 180 grados.
Podemos dibujar de la siguiente manera: elegir 5 vertices como si fuera un hexágono irregular cualquiera alrededor del origen de coordenadas, y luego elegir a (0,0) como el ultimo vertice. Esta es una de las varias maneras de resolverlo, no la unica .
Como ejemplo, puede ser el siguiente hexágono:
132) Si tenemos los vertices K y L, una forma de completar un triangulo isosceles con un tercer vertice es colocar este vertice en algun punto de la linea perpendicular a KL y que pasa por su punto medio.
Las coordenadas de M, el punto medio de KL se puede calcular como el promedio de las coordenadas de los extremos K y L:
[tex]Xm=\frac{xK+xL}{2} =\frac{-1+(-1)}{2} =-\frac{2}{2} =-1\\Ym=\frac{Yk+yL}{2} =\frac{2+(-4)}{2} =\frac{-2}{2} =-1[/tex]
Como la linea definida por KL es una linea vertical, sus lineas perpendiculares seran lineas horizontales. Entonces ,la recta y=-1 es perpendicular a KL y passa por el punto medio de KL.
Cualquier vertice con coordenadas (x,-1), excepto (-1,-1) , formaran un triangulo isosceles.
Como ejemplo , seleccionemos un vertice en (5,-1):
Como tenemos un eje de simetria en y=-1 , el triangulo KLM es isosceles.
132) Si tomaremos el ejemplo anterior y nos corrieramos del eje de simetria obterndriamos un triangulo escaleno, es decir, con 3 lados con distintas longitudes.
NOTA: Tener cuidado que por casualidad no coincidan KM o LM con KL (longitud 6).
Por ejemplo, si corremos M hasta (5,0) obtendremos un triangulo isosceles, dado que el segmento KM tendria longitud 6, al igual que KL.
Para asegurarnos que los tres lados tengan longitudes diferentes, formamos un triangulo rectangulo con dos catetos con diferentes longitud. Un cateto es KL, de longitud 6, y el otro cateto sera KM , de longitud 3 si colocamos a M en (2,2):

Answer:
m(∠KJL) = 54°
Step-by-step explanation:
It's given that two sides of ΔJKL are equal in measure.
Therefore, angles opposite to the equal sides will be equal.
By triangle sum theorem in ΔJKL,
m∠KJL + m∠KLJ + m∠JKL = 180°
2(m∠KJL) + 72° = 180°
2(m∠KJL) = 180° - 72°
m∠KJL = [tex]\frac{108}{2}[/tex]
m(∠KJL) = 54°

Answer:
6 and 15
Step-by-step explanation:
x^2 + 9x = x^2 + 7x +12
2x = 12
x = 6
The dimension of the original rectangles are 6 inche and 15 inches.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Original rectangle:
Length = x + 9
Width = x
Area = (x + 9)x
New rectangle:
Length = (x + 9) - 5 = x + 4
Width = x + 3
Area = (x + 4)(x + 3)
Now,
(x + 9)x = (x + 4)(x + 3)
x² + 9x = x² + 3x + 4x + 12
9x = 7x + 12
9x - 7x = 12
2x = 12
x = 6
Now,
The dimension of the original rectangle.
x + 9 = 6 + 9 = 15
x = 6
Thus,
The dimensions of the rectangles are 6 inches and 15. inches

6 milk chocolates are expired
Step-by-step explanation:
This same question is answered by RenatoMattice. This is what the answer says:
Since we have given that
Total number of chocolates = 15
Types of chocolates are as follows:
1) Milk chocolates
2) Dark chocolates
3) Mix
According to question,
Number of milk chocolates that are expired = 6
Number of dark chocolates that are expired = 3
total number of chocolates that are expired = 6+3=9
And we have mentioned that 6 milk chocolates that are not expired.
and 9+6=15
No other chocolates are left in a case of chocolate.
so, only mentioned 6 milk chocolates are expired.

Answers
Answer:
This question is unsolvable because:
1) Volume can't be measured in cm (think you mean cm^3)
2) Volume of the cylinder is calculated with its height and bottom area.
We can calculate its bottom area like this: (4/2)^2*pi
But since we do not know the cylinder nor the cones' height then we can't
calculate their volume.
