The three (3) statements which are true include the following:

A. The radius of the circle is 3 units.

B. The center of the circle lies on the x-axis.

D. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Mathematically, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²   ....equation 1.

Where:

h and k represents the coordinates at the center of a circle.

r represents the radius of a circle.

From the information provided, we have the following equation of a circle:

x² + y² – 2x – 8 = 0      ......equation 2.

In order to determine the true statements, we would rewrite the equation in standard form and then factorize by using completing the square method:

x² – 2x + y² = 8 = 0

x² – 2x + (2/2)² + y² = 8 + (2/2)²

x² – 2x + 1 + y² = 8 + 1

(x – 1)² + (y - 0)² = 9         .......equation 3.

Comparing equation 1 and equation 3, we have the following:

Center (h, k) = (1, 0)

Radius, r = 3

Additionally, this line and the circle's center lies on the x-axis because the y-value is equal to zero (0).

(x – 0)² + (y - 0)² = 3²

x² + y² = 9.

In order to build a cube with an edge length of b inches, b3 cubes with 1-inch edges are required.

A cube is a three-dimensional object with six square faces that are all the same size and form in mathematics. A cube has perpendicular sides and is symmetrical along all three axes. Finding the area of one of a cube's faces and increasing it to the third power yields the volume of the object. V=s3, where s denotes one of the cube's sides, is the formula for calculating a cube's volume. Cubes are frequently used in geometry and algebra, and they have a wide range of real-world uses, including volume measurement and the solution of mathematical equations.

How to solve?

The volume of a cube with an edge length of b inches is b3 cubic inches. For instance, if b=3, we would require 33=27 cubes with 1 inch-long edges, and the volume of a cube with a three inches edge would be 33=27 cubic inches.

The 480 chairs were all finished by the employees in 4 days while maintaining a steady pace.

Time and work deals with the time taken by an individual or a group of individuals to complete a piece of work and the efficiency of the work done by each of them.

Work Done = Time Taken × Rate of Work.

Rate of Work = 1 / Time Taken.

Time Taken = 1 / Rate of Work.

If a piece of work is done in x number of days, then the work done in one day = 1/x.

Total Work Done = Number of Days × Efficiency.

Here,

Total number of chairs=480

Chairs left to work on=120

It took them 3 days to install 360 chairs which means if they were working at a constant rate they got 120 chairs installed daily.

With 120 chairs left that means in 1 days they will finish.

So overall, it took the workers 4 days to finish.

Answer:

To calculate the distance between the points -5, -3 and -5, -6. We apply the following formula:

(x₁, y₁) and (x₂, y₂)   d = √(x₂ - x₁)² + (y₂ - y₁)²

The points are:

 (x₁ = -5, y₁ = -3) and (x₂= -5, y₂= -6)

We apply the above formula and solve.

The distance between the points -5, -3 and -5, -6 is 3.

To find the 3 smallest positive x-intercepts of the graph of y = cos(12x) + cos(16x), you can use the following steps:

Set y equal to 0 and solve for x to find the x-intercepts of the graph.

Since the graph of y = cos(12x) + cos(16x) is periodic with period 2π/12 = π/6 and 2π/16 = π/8, respectively, you only need to consider x-intercepts in the interval [0,π/6).

Use the identity cos(a+b) = cos(a)cos(b) - sin(a)sin(b) to rewrite the equation y = cos(12x) + cos(16x) as:

y = 2cos(4x)cos(8x) - sin(4x)sin(8x)

Set y equal to 0 and solve for x to find the x-intercepts. This will give you the x-coordinates of all the x-intercepts of the graph.

Sort the x-coordinates in increasing order and take the first three smallest positive values to find the 3 smallest positive x-intercepts.

For example, if you set y equal to 0 and solve for x, you get:

0 = 2cos(4x)cos(8x) - sin(4x)sin(8x)

This equation can be rewritten as:

cos(4x)cos(8x) = sin(4x)sin(8x)

Using the identity cos(a) = sin(π/2 - a) and substituting this into the equation above, we get:

sin(4x)sin(8x) = sin(4x + π/2)sin(8x)

This equation simplifies to:

sin(4x)sin(8x) = sin(4x)cos(8x)

Dividing both sides by sin(4x) and rearranging, we get:

sin(8x) = cos(8x)

This equation holds for all values of x that satisfy sin(8x) = cos(8x), so we can find the x-intercepts by setting these two functions equal to each other and solving for x:

sin(8x) = cos(8x)

sin^2(8x) = cos^2(8x)

sin^2(8x) - cos^2(8x) = 0

1 - cos(16x) = 0

cos(16x) = 1

Thus, the x-intercepts of the graph are at x = 0, x = π/16, x = π/8, x = 3π/16, and so on. Since we are only interested in the 3 smallest positive x-intercepts, we can take the first three values in this list: x = 0, x = π/16, and x = π/8.

Therefore, the 3 smallest positive x-intercepts of the graph of y = cos(12x) + cos(16x) are [0, π/16, π/8].

The sum of two successive odd integers must be at least 16, hence the inequality will be x+1≥4 and the solution will be x≥3.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

Here,

Sum of 2 consecutive odd integer=16

Let them be 2x+1 and 2x+3,

2x+1+2x+3≥16

4x+4≥16

x+1≥4

x≥3

The inequality will be x+1≥4 and solution to the inequality will be x≥3 as sum of two consecutive odd integers is at least 16.

What is fraction ?

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

To derive a solution, you have to subtract the meter of rope that Sam has from the meter of rope he cut for a project.  

Therefore,

1½ - 5/8,  

Since the meter of rope Sam had is represent with a mixed fraction, we have to convert it to an improper fraction, and therefore 1½ can also be written as 3/2

Therefore, we have

3/2 – 5/8

To solve this fraction, you need to find the smallest number that can divide the denominator (2 and 8), which is 8.  

Now divide the denominators with 8 and multiply the answers you get by the numerators.

Therefore, we have

3/2 -5/8

= 12/8 – 5/8

= 7/8 m.

Therefore, Sam has 7/8 m of rope left.

The smallest number used to divide the denominators is also known as the lowest common denominator (LCD).

A fraction has 2 parts, which are numerator and denominator. The numerator is the number at the top in a fraction while the denominator is the number below in a fraction.

After 7 years  the laptop computer will be worth $200 or less.

In this question, we have been given a laptop computer is purchased for $1500 . Each year, its value is 75%  of its value the year before.

We need to find the number of years when laptop computer be worth $200  or less.

We can see that given situation represents exponential decay function with initial value 1500, decay rate = 0.75 and the final value = 200

We need to find period t.

For given situation we get an exponential function as,

1500 * (0.75)^t ≤  200

(0.75)^t  ≤ 2/15

t * ln(0.75) ≤ ln(2/15)

t * (-0.2877) ≤ -2.0149

Answer: Statements 1, 3, and 4 are not true. The sum, difference, and quotient of two negative integers can be positive, negative, or zero, depending on the values of the two integers. For example, the sum of -5 and -7 is -12, which is a negative number. The difference of -5 and -7 is 2, which is a positive number. The quotient of -5 and -7 is -0.7142857142857143, which is a negative number.

Only statement 2 is true. The product of two negative integers is always a positive number. For example, the product of -5 and -7 is 35, which is a positive number. This is because the two negative signs "cancel out" when multiplying two numbers, resulting in a positive product.
