Answer:

x = 14

Step-by-step explanation:

12(3x - 2) = 32(x + 1) ← distribute both sides

36x - 24 = 32x + 32 ( subtract 32x from both sides )

4x - 24 = 32 ( add 24 to both sides )

4x = 56 ( divide both sides by 4 )

x = 14

The value of x given that JKL ~ MKN is; x= 14.

According to the question;

Based on ratios; We can conclude that;

[tex] \frac{12}{x + 1} = \frac{32}{3x - 2} [/tex]

By cross product, we have;

x = 14.

Ultimately, the value of x given that JKL ~ MKN is; 14.

the answer is 288:)

Step-by-step explanation:

The volume of the sphere in terms of π is,

⇒ 288π inch³

Multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Radius of sphere = 6 inch

Now, We know that;

Volume of sphere = 4/3πr³

Hence, We can formulate;

⇒ V = 4/3 × π × 6³

⇒ V = 288π inch³

Thus, The volume of the sphere in terms of π is,

[tex]\frac{1}{4x^2\left(x+1\right)}[/tex]

Step-by-step explanation:

[tex]\frac{2x-16}{8x^3+56x^2}\cdot \frac{x+7}{x^2-7x-8}[/tex]

You first factor things out.

[tex]\frac{x-8}{4x^2\left(x+7\right)}\cdot \frac{x+7}{x^2-7x-8}[/tex]

You then multiply. (Cancel common factor, X+7)

[tex]\frac{x-8}{4x^2\left(x^2-7x-8\right)}[/tex]

You factor again.

[tex]\frac{x-8}{4x^2\left(x+1\right)\left(x-8\right)}[/tex]

Then cancel out common fact x-8.

So therefore, you get the final answer,

Answer:

You don't have a question but I'll answer what I can.

half-life = natural log (.5) / k

half-life =  -.693147 / .1247

half-life = 5.561106656

It seems you did not express the k-value properly.

1) A k-value should have a negative value.

2) A k-value should also have units.

For example, the k-value of tungsten 181 is

-0.005723757 / days

Step-by-step explanation:

Final answer:

a half-life of 5.5 days.

Explanation:

To find the half-life (t1/2) using the decay constant (k), the formula that relates them for the decay of a radioactive substance, typically used for first-order kinetics, is t1/2 = ln(2)/k, where ln(2) is the natural logarithm of 2. Given the decay constant k = 0.125, the half-life is calculated as follows:

t1/2 = ln(2) / 0.125

t1/2 = 5.545 / 0.125

t1/2 = 5.5 days

The mass of the substance does not affect the half-life, so the initial 11-gram sample size is not used in the calculation. Thus, the substance's half-life, rounded to the nearest tenth, is 5.5 days.

Answer:

Table 1

Step-by-step explanation:

Constant of proportionality is simply the ratio of y to x. In each of the given tables, the second column is y and the first is x.

Table 1:

4       32/5

10      16

11       88/5

Let's find the constant of proportionality for each row:

R1: (32/5) / 4 = 8/5

R2: 16/10 = 8/5

R3: (88/5) / 11 = 8/5

Thus, since this matches the requirements and all three rows have the same constant, Table 1 is the answer.

If you check the other two tables in the same way, you'll see that neither has a constant of proportionality of 8/5.

Hope this helps!

Answer:

Table 1

Step-by-step explanation:

y = (8/5)x

32/5 = 8/5 × 4

32/5 = 32/5

16 = 32/5 × 10

16 = 16

88/5 = 8/5 × 11

88/5 = 88/5

Answer:

The number of buyers on the first day was approximately 324.

Step-by-step explanation:

In this case we have a initial number of shoppers "C" that we want to know and this grows at a steady rate of 20% per day, like a compound interest, we also know the total number of shoppers after 4 days, so we have the final amount of shoppers. We can use the formula for compound interest in order to calculate the number of shoppers in the first day as shown bellow:

M = C*(1 +i)^(t)

Where M is the total amount of shoppers, i is the growth rate and t is the time elapsed.

671 = C*(1 + 0.2)^(4)

671 = C*(1.2)^4

671 = C*2.0736

C = 671/2.0736 = 323.5918

Since there can't be a 0.59 buyer, we will round the number to 324.

Answer:

10(3)^x

Step-by-step explanation:

The function contains the points (2,90) and (4,810). Use the general form y=abx to write two equations:

90=ab^2 and 810=ab^4

Solve each equation for a:

a=90/b^2 and a=810/b^4

Since a=a, set the other sides of the equations equal and solve for b.

90/b2=810/b4

Cross multiply, then divide and simplify as follows:

90b^4=810b^2

b^4/b^2=810/90

b^2=90

b^3

Now, use the value of b and the point (2,90) to find the value of a.

90=a(3^2)

a=10

So, substitute answers in original equation for a final answer of f(x)=10(3)^x.

Answer:

What is the radius of the cone?

5ft

What is the area of the base of the cone?

25ft

What is the volume of the cone?

75ft

Step-by-step explanation:

1) Radius of the cone = 5ft

2) Area of the base of the cone =  78.5 square feet

3) Volume of the cone = 235.5 cubic feet

A cone is a distinctive three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top. The pointed end of the cone is called the vertex, whereas the flat surface is called the base.

According to the given problem,

Diameter of the cone = 10 feet

Radius of the cone = [tex]\frac{diameter}{2}[/tex]

                                = 5 feet

Area of the base of the cone = [tex]\pi[/tex]r²

                                                 = [tex]\pi[/tex] × (5)²

                                                 = 78.5 square feet

Volume of the cube = [tex]\pi[/tex]r²[tex](\frac{height}{3})[/tex]

                                  = 235.5 cubic feet

Hence, we can conclude that the cone shown in figure has a radius of 5 feet , base area of 78.5 feet and a volume of 235.5 cubic feet.

Answer:

y = 3x+2

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

   = (23-20)/(7-6)

    =3/1

We know the slope is 3

Using the slope intercept form of a line

y= mx+b where is the slope and b is the y intercept

y = 3x+b

Using a point (1,5)

5 = 3(1)+b

Subtract 3 from each side

5-3= 3-3+b

2 = b

y = 3x+2

Answer:

B) y = 3x + 2

Step-by-step explanation:

Slope: (8 - 5)/(2 - 1)

= 3/1 = 3

y = 3x + c

5 = 3(1) + c

c = 5 - 3

c = 2

y = 3x + 2

Period is 4, Amplitude is 3.5

Step-by-step explanation:

The Period is how far in the x direction for a function to repeat. This function repeats at (1,5), (5,5), etc. 5-1 = 4 difference between points which is the period.

The Amplitude is defined as the vertical distance from the center. The maximum vertical distance is 5 and the minimum is -2. 5-(-2) = 7. 7/2 = 3.5. 3.5 is the average which is the amp.

The solution is :Period is 4, Amplitude is 3.5, of the function.

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.

here, we have,

The Period is how far in the x direction for a function to repeat.

This function repeats at (1,5), (5,5), etc.

5-1 = 4 difference between points which is the period.

we have,

Answer:

≈ 1347 mi²

Step-by-step explanation:

The shaded area is the difference between the outer area and the inner area

shaded area = outer - inner

                     = πr₁² - πr₂²

where r₁ = 14 + 11 = 25 and r₂ = 14, thus

A = π × 25² - π × 14² = 625π - 196π = 429π = 429 × 3.14 ≈ 1347 mi²

Answer:

Step-by-step explanation:

Area of the shaded region = Area of the Outer circle - Area of the inner circle

Outer circle:

r = 14+11 = 25 mi

Area = πr² = π*25²

Inner Circle:

r = 14 mi

Area = πr² = π*14²

Area of shaded region = π*25² - π*14²= π(25² - 14²)

= 3.14*(625 - 196)

=3.14*429

= 1347.06 mi²
