[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]

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).

Answer:

x = 16

Step-by-step explanation:

The two angles are vertical angles

Vertical angles are congruent

That being said we can create an equation

4x - 7 = 3x + 9

now we solve for x

step 1 add 7 to each side

9 + 7 = 16

-7 + 7 cancels out

now we have 4x = 3x + 16

step 2 subtract 3x from each side

4x - 3x = x

3x - 3x cancels out

we're left with x = 16

Answer:

0.65

Step-by-step explanation:

The probability that a randomly selected student is in sports is 0.65.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

Given that, the number of students = 100.

Total number of outcomes =100

Number of favorable outcomes =65

Now, P(Sports) = 65/100

= 0.65

The probability that a randomly selected student is in sports is 0.65.

Step-by-step explanation:

TRUST ME IT IS CORRECT

Answer:

x⁴

Step-by-step explanation:

(∛x²)⁶ {The cube root of x² is x^(2/3)}

(x^(2/3))⁶ {Now, simply multiply 2/3 by 6 to get 4.}

x⁴

(∛x²)⁶ is equivalent to x⁴.

Answer:

Solution given:

diameter [d]=16m

radius [r]=8m

let slant height =l

surface area =628.32m²

πr(r+l)=628.32m²

π×8(8+l)=628.32

8+l=628.32/(8π)

8+l=25

l=25-8

l=17m

now

height of cone [h]=√{17²-8²}=15m

Again

Volume of cone =⅓πr²h=⅓×π×8²×15=320π 0r 1005.31m³

The required volume is 320π 0r 1005.31m³

The Volume of the given Cone is: 1005.469 cubic. cm.

V=1005.469 cubic. cm.

The volume of a 3 -dimensional solid is the amount of space it occupies.

The volume V of a cone with radius r is one-third the area of the base B times the height h .

V= [tex]\frac{1}{3} \pi r^{2} h[/tex]

Surface area of cone= 628.32

[tex]\pi r(l+r)[/tex]= 628.32

3.14 x 8 (l + 8)= 628.32

l+8= 25.01

l= 17.01 cm

height= 15.01 cm

Now volume of cone,

V= [tex]\frac{1}{3} \pi r^{2} h[/tex]

  = [tex]\frac{1}{3} *3.14 *8^{2}* 15.01[/tex]

  =1005.469 cubic. cm.

volume of cone, V= 1005.469 cubic. cm.

Answer:

D

Step-by-step explanation:

multiply by 8 on both sides

(20)8 - 8(4b/8) = (18)8

160 - 4b = 144

subtract 160 on both sides

160 - 160 - 4b = 144 - 160

-4b = -16

divide by -4 on both sides

-4b/-4 = -16/-4

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...

Answer:

A=30

Step-by-step explanation:

Set your equation up as following:

180=90+(x+37)+(x+67)

180=90+37+67+2x

180-90-37-67=2x

-14=2x

-14/2=x

-7=x

Angle A = x+37

A=-7+37

A=30

Answer:

m<A = 30

Step-by-step explanation:

The right square is a 90 degree angle

All angles in a triangle add up to 180 so:

x + 37 + x + 67 + 90 = 180

2x + 194 = 180

2x = 180 - 194

2x = -14

x = -7

x + 37

Step-by-step explanation:

A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

By using distance formula (which is attached below), you can solve this problem:

√(x2-x1)^2+(y2-y1)^2

(5, -1) and (5, 3)

√(5-5)^2+(3-(-1))^2

Answer:

1.) 12000

2.) 6750

3.) 2.41

Step-by-step explanation:

Given the Equation :

f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t

When, car was purchased, t = 0

t = 0

f(0) = 12000(3/4)^0

= 12000 * 1

= 12000

2.)

f(2) ; this mean the worth of the car after 2 years :

f(2)=12,000(3/4)^t.

12000(3/4)^2

12000 * 0.5625

= 6750

When car will be worth 6000

f(t) = 6000

f(t)=12,000(3/4)^t.

6000 = 12,000(3/4)^t

6000 / 12000 = (3/4)^t

1/2 = (3/4)^t

Take the log of both sides :

Log(0.5) = log(0.75)^t

log(0.5) = tlog(0.75)

- 0.301029 = - 0.124938t

t = - 0.301029 / - 0.124938

t = 2.4094

t = 2.41 years
