Cual transformación produce acercamientos de las gráficas al eje de Y en el plano de coordenadas

2 answers:

7 0

El plano de coordenadas se desarrolló hace cientos de años y fue refinado por el matemático Francés René Descartes. En su honor, se le conoce también como sistema de coordenadas Cartesianas. El plano de coordenadas puede usarse para graficar puntos y rectas. Este sistema nos permite describir relaciones algebraicas de una manera visual, y también nos ayuda a interpretar conceptos algebraicos.

Answer:

El eje horizontal en el plano de coordenadas se llama eje-x. El eje vertical se llama eje-y. El punto en el que los dos ejes se intersectan se llama origen.

Answer:

1/4

3/8

5/8

2/5

Step-by-step explanation:

From the table :

1.)

P(9th grade) = (9th grade total / total) = 4 / 16 = 1/4

2.)

P(comedy) = (comedy total / total) = 6 / 16 = 3/8

3.)

P(not action) = 1 - P(action) = 1 - (action total / total) = (1 - 6/16) = 1 - 3/8 = 5/8

4.)

P(comefy | 10th grade) = P(comedy n 10th grade) / P(10th grade) = 2 / 5

Four identical right triangles whose sides measure 5x, 12x, and 13x are arranged to form a small square inside a large square, a

Simora [160]

Answer:

The perimeter of the small square is approximately 9.154 units

Step-by-step explanation:

The given parameters are;

The sides of the four identical right triangles = 5·x, 12·x, and 13·x,

The perimeter of the large square = 17 units

Therefore, we have;

The hypotenuse side of the right triangles = The longest side = 13·x

The sides of the large square are formed by the hypotenuse sides of the right triangle

Therefore, the perimeter of the large square = 4 × 13·x = 52·x = 17 units

x = 17/52 ≈ 0.3269

x ≈ 0.3269 units

The sides of the small square = The difference between the longer and the shorter of the two legs = 12·x - 5·x = 7·x

∴ The sides of the small square = 7·x = (7 × 0.3269) units ≈ 2.2885 units

The perimeter of the small square = 4 × The sides of the small square

The perimeter of the small square ≈ (4 × 2.2885) units ≈ 9.154 units

The perimeter of the small square ≈ 9.154 units.

Round 9991 to the nearest thousands

stiv31 [10]

Answer:

10,000

Step-by-step explanation:

In order to round numbers we look at the number to the right of whatever we are rounding to. So in this case we are rounding to the nearest thousand so we look at the number to the right of the thousands which is the hundred in this case. If that number is a 1-4 we round down and if that number is a 5-9 we round up. In this case the number to the right is a 9 so we will round up. The nearest thousand above 9991 is 10,000 so that is what we will round to

What is the real part of the complex number 2 - i?

Pepsi [2]

Happy New Year from MrBillDoesMath!

Answer:

Discussion:

If z = a + bi is a complex number, then

the real part of z is the constant "a" and

the imaginary (or complex) part of z is the constant "b" (that is, the constant

that multiples "i")

Thank you,

Complete the square to rewrite y = x^2 + 6x + 3 in vertex form. Then state whether the vertex is a maximum or a minimum and give

AnnyKZ [126]

First of all, we convert the equation to a vertex form.
$y = x^{2}+6x+3$
$y=(x^{2}+6x)+3$
$y = (x+3)^{2}+3-9
$
$y = (x+3)^{2}-6$ .
The equation in vertex form is $(x+3)^{2}-6$ . By looking at the equation we can understand that the y value of the vertex point is -6. By further calculation we can verify that the x value of the vertex point is -3.
Now, there are two ways of finding if the vertex point is a maximum or a minimum. The first way is picking random x coordinates after and before the y vertex value. If the values of y decrease before the y vertex point and increase afterwards, the vertex is a minimum. If the values of y increase before the y vertex point and then decrease afterwards, the vertex is a maximum point. The second way is applying teh second derivative. Here, I will show you the way of doing it:
$y = x^{2} + 6x +3$
$\frac{dy}{dx} = 2x + 6$
$\frac{d^{2}y}{dx^2} = 2$
The result proves two facts about the function:
1. The function has only one vertex/turning point.
2. The vertex/turning point is a minimum (due to the result of the second derivative being positive).

The answer is C.
