The Greatest Common Factor [GCF] means the LEAST DEGREE TERM possible, plus finding a common factor, in this case, between 9 and 13, which is 1, but writing it is unnecessary.

I am joyous to assist you anytime.

The greatest common factor of 13c and 9c³ is "c".

To find the greatest common factor (GCF) of 13c and 9c³, we need to determine the largest term that divides evenly into both expressions.

First, let's break down each expression into its prime factors:

13c = 13 x c

9c³ = 3²  x c³

Now, let's identify the common factors between the two expressions:

Common factors of 13c and 9c³: c

To find the GCF, we take the product of the common factors, considering the lowest exponent for each common factor:

Answer:

4

Step-by-step explanation:

The geometric mean finds the typical value of a set of numbers through multiplication. To find the geometric mean of two numbers, you take the square root of the product of the two numbers.

So in this instance, multiply the two numbers together:

[tex]2*8=16[/tex]

And take the positive square root of the product:

[tex]\sqrt{16}=4[/tex]

The geometric mean is different than the commonly-used arithmetic mean, which finds the central value of a set of numbers by dividing the set's sum total by how many numbers are in the set.

Final answer:

The geometric mean of 8 and 2 is calculated as the square root of their product, which is 4.

Explanation:

To find the geometric mean of 8 and 2, we use the formula for geometric mean which is the square root of the product of the numbers. Therefore, the geometric mean of 8 and 2 is the square root of 8 multiplied by 2, which is √(8×2).

Let's calculate it step by step:

Hence, the geometric mean of 8 and 2 is 4.

Answer:

C). 0 degrees

Step-by-step explanation:

The given equation is:

-4 + 6 sinx = -4 + 4 sinx

adding 4 on both sides:

4 - 4 + 6 sinx = 4 - 4 + 4 sinx

6sinx = 4sinx

dividing by 2 on both sides, we get:

6sinx/2 = 4sinx/2

3 sinx = 2 sinx

subtracting 2 sinx from both sides we get:

sin x = 0

x = sin⁻¹ (0)

x = 0 degrees

Answer:

x + 2y = - 2

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Obtain the equation in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (8, - 5)

m = [tex]\frac{-5-0}{8+2}[/tex] = [tex]\frac{-5}{10}[/tex] = - [tex]\frac{1}{2}[/tex]

y = - [tex]\frac{1}{2}[/tex] + c ← partial equation of line

To find c substitute either of the 2 points into the partial equation

Using (- 2, 0), then

0 = 1 + c ⇒ c = - 1

y = - [tex]\frac{1}{2}[/tex] x - 1 ← in slope- intercept form

Multiply through by 2

2y = - x - 2 ( add x to both sides )

x + 2y = - 2 ← in standard form

Step-by-step explanation:

To calculate the total surface area of a hemisphere with a radius of 8 cm, we use the formula A = 3πr², resulting in a total surface area of approximately 602.9 cm² to one decimal place.

The question asks us to work out the total surface area of a hemisphere with a radius of 8cm and provide the answer to one decimal place. The total surface area of a hemisphere is given by the formula A = 2πr² + πr², where π is approximately 3.14 and r is the radius of the hemisphere. The first part 2πr² represents the curved surface area, and the second part πr² represents the area of the circular base.

Substituting 8 cm for r:

A = 2π(8²) + π(8²) = 2π(64) + π(64) = 128π + 64π = 192π cm²

Converting π to 3.14:

A = 192(3.14) = 602.88 cm². Therefore, the total surface area of the hemisphere is approximately 602.9 cm² to one decimal place.

The total surface area of this hemisphere is approximately 603.2 cm².

Calculating the Total Surface Area of a Hemisphere

To find the total surface area of a hemisphere with a radius of 8 cm, we need to consider both the curved surface area and the base area.

Curved Surface Area: The formula for the curved surface area of a hemisphere is given by 2πr², where r is the radius. Substituting the given radius (8 cm), we get:

Curved Surface Area = 2π(8 cm)² = 2π(64 cm²) ≈ 2 × 3.1415927 × 64 = 402.1 cm² (rounded to one decimal place)

Base Area: The base of the hemisphere is a circle with the area given by the formula πr². Using the radius (8 cm), we get:

Base Area = π(8 cm)² = π(64 cm²) ≈ 3.1415927 × 64 = 201.1 cm² (rounded to one decimal place)

Total Surface Area: To find the total surface area, we sum the curved surface area and the base area:

Total Surface Area = 402.1 cm² + 201.1 cm² = 603.2 cm²

Therefore, the total surface area of the hemisphere is approximately 603.2 cm².

Final answer:

The future value of the house will be approximately $232,810.10 in 10 years, calculated by compounding the initial value of $130,000 at an annual growth rate of 6%.

Explanation:

To calculate the future value of a house appreciating at a certain rate, we can use the compound interest formula: [tex]Future\ Value = Present\ Value \* (1 + growth/decay rate)^{number of periods[/tex]

In this scenario, the house is appreciating, which means it's increasing in value over time.

We're given that the initial amount (Present Value) is $130,000 and the growth rate is 6% per year.

The function that represents the situation is:
Future Value = $130,000 × (1 + 0.06)¹⁰

To find the value of the house in 10 years, we simply plug in the values:

Future Value = $130,000 × (1 + 0.06)¹⁰
Future Value = $130,000 × (1.06)¹⁰
Future Value = $130,000 × 1.790847
Future Value = $232,810.10 approximately

Therefore, the house will be worth approximately $232,810.10 in 10 years, and this represents growth, not decay.

Answer:

Step-by-step explanation:

"Rectangular" includes "square," and in fact treating the rectangle as a square is the fastest way to "solve" this problem.  The perimeter of the rectangular area is 160 ft; dividing that by 4 yields 40 ft.  "40 ft square" describes the rectangle maximum area:  (40 ft)^2 = 1600 ft^2.

Alternatively, let W and L represent the width and length of the rectangle.  Then:

P = perimeter = 2W + 2L = 160 ft, or W + L = 80 ft, or W = 80 ft - L.

A = area = L*W = L(80 ft - L) = 1600 ft^2.  Rewriting this as a proper quadratic:

80L - L^2 - 1600 = 0, or  L^2 - 80L + 1600.  Note that this last result factors into (L - 40)^2 = 0, so L = 40 ft.  Then W = 80 ft - 40 ft = 40 ft.

This confirms that the max area is 1600 ft^2 = (40 ft)^2.

Step-by-step explanation:

a:

4x - 5 = 16

isolate the variable. this is done by putting only the variable on the left side and the numbers on the right side. when moving the 5 to the right side, it is counted as a -5 because of the minus in front. when moving it, be sure to change from - to + and vice versa.

4x = 16 + 5

4x = 21

x = 21/4

x = 5.25

b:

3x = -12 + 11

3x = -1

x = -0.33

Hope I could help! If you have any trouble, tell me in the comments.

Answer:

a. [tex]x=5.25[/tex]

b. [tex]x=-0.33[/tex]

Step-by-step explanation:

You need to solve for the variable "x" in each equation. Then:

a. You need to add 5 to both sides of the equation:

[tex]4x - 5 +(5)= 16+(5)\\\\4x= 21[/tex]

Now you need to divide both sides of the equation by 4, getting:

[tex]\frac{4x}{4}=\frac{21}{4}\\\\x=5.25[/tex]

b. You need to subtract 35 from both sides of the equation:

[tex]35 + 3x - 11-(35)= 23-(35)\\\\3x-11=-12[/tex]

Add 11 to both sides:

[tex]3x-11+(11)=-12+(11)\\\\3x=-1[/tex]

Now you need to divide both sides of the equation by 3, getting:

[tex]\frac{3x}{3}=\frac{-1}{3}\\\\x=-0.33[/tex]

Answer:

Step-by-step explanation:

The intersection is the point where two equations meet. It is calculated by substituting terms into the equations involved. For the given systems of equation, calculations are as follows:

2x - y = 6

y = 2x - 6

We substitute the equation above to the second equation.

5x + 10y = –10

5x + 10( 2x - 6 )= –10

Simplifying, 

5x + 20x - 60 = -10

25x = 50

x = 2

Therefore, the intersection has the value of x equal to 2.

Answer with Step-by-step explanation:

The point of intersection of the graphs of system of equation is the solution to the system of equations.

So, we need to find the solution of the system of equations:

2x – y = 6

5x + 10y = –10

Multiplying first equation by 10 and add it to second equation.

5x+10y+10(2x-y)= -10+60

5x+10y+20x-10y=50

25x=50

⇒ x=2

Hence, value of x where the graphs of the equations  

2x – y = 6

5x + 10y = –10 intersect is:

x=2

The correct answer option is quadratic, because the height increases and then decreases.

Step-by-step explanation:

We are given the following data in the table which represents the height of an object over  time:

Time (s)          Height (ft)

     0                      5

      1                     50

     2                     70

     3                     48

We know that in situation where the values increase and then decreases, a quadratic model is used.

From the values given in the table, we can see that the values of height first increased and then decreased with the increase in time.

Therefore, the model used is quadratic, because the height increases and then decreases.
