Last Option

Step-by-step explanation:

Answer:

[tex]pH = 13[/tex] --- Oven Cleaner

[tex]pH = 6.2[/tex] --- Water

[tex]pH =7.4[/tex] --- Blood

[tex]pH = 2.2[/tex] --- Vinegar

Step-by-step explanation:

The given molar concentration are:[Missing from the question]

Oven Cleaner: [h+] = [tex]10^{-13}[/tex]

Water: [h+] = [tex]0.0000007[/tex]

Blood: [h+] = [tex]0.00000004[/tex]

Vinegar: [h+] = [tex]0.0063[/tex]

Required

Determine the pH

pH is calculated using:

[tex]pH = -\log(h+)[/tex]

So, we have:

Oven Cleaner:

[tex]pH = -\log(10^{-13})[/tex]

Using a calculator, we have:

[tex]pH = 13[/tex]

Water:

[tex]pH = -\log(0.0000007)[/tex]

Using a calculator, we have:

[tex]pH = -1*-6.2[/tex]

[tex]pH = 6.2[/tex]

Blood:

[tex]pH = -\log(0.00000004)[/tex]

Using a calculator, we have:

[tex]pH = -1 * -7.4[/tex]

[tex]pH =7.4[/tex]

Vinegar:

[tex]pH = -\log(0.0063 )[/tex]

Using a calculator, we have:

[tex]pH = -1 * -2.2[/tex]

[tex]pH = 2.2[/tex]

A. A single fixed point that is half the distance from the parabola as the direction is from the paranola

A single fixed point that is half the distance from the parabola as

the directrix is from the parabola. Therefore, option A is the correct answer.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix. The focus lies on the axis of symmetry of the parabola.

Therefore, option A is the correct answer.

Answer:

0.64                        

Step-by-step explanation:

Answer:

P = 15/36 = 0.4166...

Step-by-step explanation:

Cada dado tiene 6 caras, con los números entre 1 y 6.

Entonces tenemos dos eventos, con 6 posibles resultados cada uno.

El número total de resultados para el evento de lanzar los dos dados, es el producto de los números de resultados para cada dado, entonces tenemos:

C = 6*6 = 36 posibles resultados.

Ahora tenemos que contar el número de resultados en donde la suma es menor a 7.

Usando la notación:

(resultado del dado 1) y (resultado del dado 2) = suma

Esos son:

1 y 1  = 2

1 y 2 = 3

1 y 3 = 4

1 y 4 = 5

1 y 5 = 6

2 y 1 = 3

2 y 2 = 4  

2 y 3 = 5

2 y 4 = 6

3 y 1 = 4

3 y 2 = 5

3 y 3 = 6

4 y 1 = 5

4 y 2 = 6

5 y 1 = 6

Hay 15 resultados donde la suma de los resultados individuales es menor a 7.

Entonces de un total de 36 posibles resultados, 15 cumplen lo que queremos, asi que la probabilidad de que las caras hacía arriba sumen un número menor que 7 son de 15 entre 36, o:

P = 15/36 = 0.4166...

43.0 square centimeters of paper are required to make each wristband.

The curved surface of a cylinder is equal to a rectangle whose length is

2[tex]\pi[/tex]r and whose width is h.

The area of the curved surface = [tex]\pi dh[/tex].

Given

Height of wrist band =  1.8 cm

Diameter of wrist band =7.5 cm

Wrist band is a cylinder

Area of curved surface

S = [tex]\pi dh[/tex]

= 3.14 × 7.5 × 1.8

= 42.9552 ≅ 43.0 [tex]cm^{2}[/tex]

Hence, 43.0 square centimeters of paper are required to make each wristband.

Step-by-step explanation:

Given:

The equation of the parabola is:

[tex]y=x^2+6x[/tex]

To find:

The y-intercept of the parabola.

Solution:

We have,

[tex]y=x^2+6x[/tex]

Putting [tex]x=0[/tex] in the given equation, we get

[tex]y=(0)^2+6(0)[/tex]

[tex]y=0+0[/tex]

[tex]y=0[/tex]

Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).
