Step-by-step explanation:
Given the equation for the cross section of a parabolic satellite TV dish:
y=1/50x^2
Equation of a parabola :
(y - k) = 1/4p * (x - h)^2
Distance of the focus from the Vertex = p
Comparing both equations :
1/4p * (x - h)^2 = 1/50 * x^2
4p = 50
Divide both sides by 4
4p/4 = 50/4
p = 12.5 inches

Dilate quadrilateral ABCD again with the origin as the center of dilation and a scale factor of -0.5. Note the side lengths of the corresponding sides in each quadrilateral. Round your answers to the hundredths place. Verify that the ratio of each side length of A′1B′1C′1D′1 to the corresponding side length of ABCD is equal to the dilation factor.
Answer:
A' (-0.20, -0.75)
B' (-1.50, -1.50)
C' (-1.79, -0.29)
D' (-10.45, -0.20)
Step-by-step explanation:
you just need to multiply all the points by -0.5, sorry not sure how to verify the ratios for the sidelength tho
The coordinates of the dilated quadrilateral are A'(-0.2, -0.75), B'(-1.5, -1.5), C'(-1.79, -0.285) and D'(-1.045, -0.2) and the ratio of each side length of A'B'C'D' to the corresponding side length of ABCD is equal to the dilation factor.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
We need to Dilate quadrilateral ABCD again with the origin as the center of dilation and a scale factor of -0.5.
The side lengths of the corresponding sides in each quadrilateral.
A(0.4, 1.5)
B(3, 3)
C(3.58, 0.57)
D(2.09, 0.4)
The scale factor is -0.5.
Now A'=(-0.4×0.5, -1.5×0.5)
=(-0.2, -0.75)
B'=(3×-0.5, 3×-0.5)
=(-1.5, -1.5)
C'=(3.58×-0.5, 0.57×0.5)
C'=(-1.79, -0.285)
D'=(2.09×-0.5, 0.4×-0.5)
D'=(-1.045, -0.2)
Hence, the coordinates of the dilated quadrilateral are A'(-0.2, -0.75), B'(-1.5, -1.5), C'(-1.79, -0.285) and D'(-1.045, -0.2) and the ratio of each side length of A'B'C'D' to the corresponding side length of ABCD is equal to the dilation factor.

Write a function for the graph of y=3x+7 after the slope is doubled.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]y=3x+7[/tex]
As we know that the slope-intercept of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so comparing the equation [tex]y=3x+7[/tex] with the slope-intercept of the line equation, we conclude that
[tex]y = 3x+7[/tex]
[tex]m = 3[/tex]
So, the slope of the line is [tex]m = 3[/tex]
As the function is
[tex]y = 3x+7[/tex]
Now, if we double the slope,
The slope will become: 2m = 2(3) = 6
Therefore, the function of the graph after doubling the slope will become:
[tex]y = 6x+7[/tex]

En la sala de una casa hay una gran ventana de vidrio, por la que se presenta una pérdida significativa de calor; las medidas de la ventana son 2,5 m x 1,5 m y 2,8 mm de espesor. Hallar la variación de calor en la unidad de tiempo si la temperatura exterior del vidrio es 16°C y la temperatura interior del vidrio es 20°C
Answer:
La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.
Step-by-step explanation:
Asumamos que la transferencia de calor es enteramente por conducción, en estado estable y unidimensional´y que la ventana es representada por una placa plana. Bajo estas consideraciones, la ecuación de conducción es la siguiente:
[tex]\dot Q = \frac{k\cdot w\cdot h}{l}\cdot (T_{i}-T_{o})[/tex] (1)
Donde:
[tex]\dot Q[/tex] - Tasa de transferencia de calor, medida en watts.
[tex]k[/tex] - Conductividad térmica, medida en watts por metro-grado Celsius.
[tex]w[/tex] - Ancho de la ventana de vidrio, medido en metros.
[tex]h[/tex] - Altura de la ventana de vidrio, medida en metros.
[tex]l[/tex] - Espesor de la ventana de vidrio, medida en metros.
[tex]T_{i}[/tex] - Temperatura interior del vidrio, medida en grados Celsius.
[tex]T_{o}[/tex] - Temperatura exterior del vidrio, medida en grados Celsius.
Si conocemos que [tex]k = 0.8\,\frac{W}{m\cdot ^{\circ}C}[/tex], [tex]w = 2.5\,m[/tex], [tex]h = 1.5\,m[/tex], [tex]l = 2.8\times 10^{-3}\,m[/tex], [tex]T_{o} = 16\,^{\circ}C[/tex] y [tex]T_{i} = 20\,^{\circ}C[/tex], entonces la tasa de transferencia de calor es:
[tex]\dot Q = \left[\frac{\left(0.8\,\frac{W}{m\cdot ^{\circ}C} \right)\cdot (2.5\,m)\cdot (1.5\,m)}{2.8\times 10^{-3}\,m} \right]\cdot (20\,^{\circ}C-16\,^{\circ}C)[/tex]
[tex]\dot Q = 4285.714\,W[/tex]
La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.

Answer:
100
Step-by-step explanation:
The angles are on the same side of the transversal. They are corresponding angles, so they are equal. Put algebraically
4a = 2a + 50 Subtract 2a from both sides.
4a-2a = 2a-2a + 50 Combine
2a = 50 Divide by 2
2a/2 = 50/2
a = 25

parallel lines A B and C D are cut by a transversal forming 8 angles labeled 1 to 8. The transversal intersecting line A B form angles 1, 2, 3, and 4 clockwise from top left. The transversal intersecting line C D form angles 5, 6, 7, 8 clockwise starting from top left.
Answer:
m∠8 = 30°
Step-by-step explanation:
Since line AB is parallel to line CD, and m∠4 = 30°, therefore:
m∠4 and m∠8 are corresponding angles.corewslinding angles are congruent.
Therefore, this means that their measure would be equal to each other, since they are congruent.
Thus:

C is the midpoint of segment AB D is the midpoint of segment BC A is located at (4,8) and B is located at (-12,4) what are the coordinates of D
Answer:
coordinates of D are ( -8, 5)
Step-by-step explanation:
- the formula of the coordinates of the midpoint is (x1+x2)/2 & (y1+y2)/2
- first we find midpoint C by using coordinates of points A and B
C => (4 - 12)/2 & (8 + 4)/2
calculate, coordinates of C are ( -4, 6 )
- now find midpoint D by using the coordinates of B and C
D => ( -12 - 4 )/2 & (4 +6)/2
calculate and the coordinates of D are ( -8, 5 )

1-La funcion lineal que pasa por el punto (3,6) tiene como expresion:
a) Y=3x+6
b) Y=6x-3
c) Y=2x
Answer:
Creo que es b
Step-by-step explanation:
The linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]
How to know if a point lies in the graph of a function?All the points (and only those points) which lie on the graph of the function satisfy its equation.
Thus, if a point lies on the graph of a function, then it must also satisfy the function.
Checking all the options to see if (3,6) lies on them:
Case 1: [tex]y = 3x + 6[/tex]Usually points are of the form (x,y). Thus, we have: (x,y) = (3,6) means x = 3, and y = 6.
Putting these values in the equation, we get:
[tex]y = 3x + 6\\6 = 3(3) + 6\\6 = 9 + 6\\6 = 15[/tex]
This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.
Case 2: [tex]y = 6x - 3[/tex]Putting x = 3, y = 6 in this equation, we get:
[tex]y = 6x - 3\\6 = 6(3) - 3\\6 = 18 - 3 \\6 = 12[/tex]
This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.
Case 3: [tex]y = 2x[/tex]Putting x = 3, y = 6 in this equation, we get:
[tex]y = 2x\\6 = 3(2)\\6 = 6[/tex]
This is correct. Thus, the point (3,6) satisfy this equation, and therefore, lies on its graph.
Thus, the linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]
