Is f/x )= 3x² a function?

Answers

Answer 1

Answer:

yes.

Step-by-step explanation:

The definition of a function:  "A function is defined as a relation between a set of inputs having one output each."

This means each x can only have 1 y value. You can check if this is a function using the vertical line test. To do the vertical line test draw vertical lines through the graph of the expression. If you even hit 2 points with a vertical line it is NOT as function.

The graph is of an upward facing parabola so it will be a function. We can graph and check this with the VLT which it passes.

Point B has coordinates ​(4,1). The​ x-coordinate of point A is -4. The distance between point A and point B is 10 units. What are the possible coordinates of point​ A?

Answers

Given:

Point B has coordinates ​(4,1).

The​ x-coordinate of point A is -4.

The distance between point A and point B is 10 units.

To find:

The possible coordinates of point​ A.

Solution:

Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The distance between point A and point B is 10 units.

[tex]\sqrt{(4-(-4))^2+(1-y)^2}=10[/tex]

Taking square on both sides, we get

[tex](8)^2+(1-y)^2=100[/tex]

[tex](1-y)^2=100-64[/tex]

[tex](1-y)^2=36[/tex]

Taking square root on both sides, we get

[tex](1-y)=\pm \sqrt{36}[/tex]

[tex]-y=\pm 6-1[/tex]

[tex]y=1\mp 6[/tex]

[tex]y=1-6[/tex] and [tex]y=1+6[/tex]

[tex]y=-5[/tex] and [tex]y=7[/tex]

Therefore, the possible coordinates of point​ A are either (-4,-5) or (-4,7).

En un parque hay una tienda donde se alquilan patines a 0,50€ la hora, monopatines a 1€ la hora y bicicletas a 2€ la hora.

Answers

Pregunta completa:

En un parque hay una tienda donde se alquilan patines a 0,50 € la hora; Patinetas a 1 € la hora y bicicletas a 2 € la hora. ¿Cuál es la ecuación de los costos en función del tiempo empleado en cada uno de los casos?

Respuesta:

C (t) = 0,50 billones de euros; C (t) = € t; C (t) = 2 billones de euros

Explicación paso a paso:

Dada la siguiente tarifa de alquiler:

Patines = 0,50 € por hora

Patinetas = 1 € por hora

Bicicletas = 2 € la hora

La ecuación de costo en función del tiempo en cada caso se puede expresar como:

Costo en función del tiempo; Connecticut)

Donde, t = tiempo

Costo, C (t) = costo por hora * Número de horas

C (t) para patines:

C (t) = 0,50 t €

Costo ; C (t) para patinetas:

C (t) = € t

Costo ; C (t) para bicicletas;

C (t) = 2 billones de euros

Answers

Answer:

10.29 (rounded = 10.30)

Step-by-step explanation:

X = a^2 + b^2 = c^2

X = 9^2 + 5^2 = c^2

X = (81) + (25) = c^2

X = 106 = c^2

X = √106 = c^2

X = 10.295630141 = c^2

X = 10.03 = c^2 (10.03 is 10.295630141 rounded to the nearest tenth)

The product of two numbers is 144, but their sum is -24. What are these two numbers?

Answers

Answer:

The two numbers are - 12 and - 12 .

Step-by-step explanation:

Let the two numbers be x and y then

By the question

x * y = 144

or x = 144 / y ....... I)

Again

x + y = - 24

Or 144/y + y = - 24

or, ( 144 + y²) / y = - 24

or, 144 + y² = - 24y

y² + 24y + 144 = 0

y² + ( 12 + 12 ) y + 144 =0

y² + 12y + 12y + 144 = 0

y(y + 12 ) + 12 ( y + 14) = 0

( y + 12 ) ( y + 12 ) = 0

Either

y + 12 =0

y = - 12

Now

x = 144 / - 12 = - 12

Therefore the two numbers are - 12 and - 12 .

Simplify the following trigonometric expression. cosθtan²θcotθ

Answers

This question requires the understanding of trigonometric identities. I'll list the ones that are needed to answer this question:

cotθ = 1 / tanθ

tanθ = sinθ / cosθ

Look at the latter identity. We can rewrite it as such:

tanθ * cosθ = sinθ

We are given the expression:

cosθ * tan²θ * cotθ

Referring to the first trigonometric identity above, substitute cotθ:

cosθ * tan²θ * (1 / tanθ)

Multiply tan²θ and the fraction:

cosθ * (tan²θ / tanθ)

cosθ * tanθ

Refer to the second trigonometric identity:

cosθ * tanθ

sinθ

cosθ * tan²θ * cotθ = sinθ

A. Rectangle ABCD has been reflected using Cas the center.
B. Rectangle ABCD has been dilated using C as the center.
C. Rectangle ABCD has been reflected using O as the center.
D. Rectangle ABCD has been dilated using O as the center

Answers

Answer is B I think that’s correct

The statement is true about the shown figures "Trapezoid ABCD has been dilated using O as the center". which is the correct answer would be an option (A).

What is a transformation?

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

here, we have,

A dilation is a transformation that generates an image with the same shape as the original but a different size. The dilation center is a fixed point in the plane. The initial figure is stretched or shrunk through dilatation.

As per the given figures,

Trapezoid ABCD has been expanded to trapezoid A'B'C'D' around the dilation center O. When the figure is expanded, the scale factor exceeds one.

Thus, the statement is true about the shown figures "Trapezoid ABCD has been dilated using O as the center".

Hence, the correct answer would be option (A).
