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.

In Mathematics, 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:

From the information provided above, 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 center of the given circle lies on the x-axis (x-coordinate) because the y-value is equal to zero (0).

(x – 0)² + (y - 0)² = 3²

x² + y² = 9.

Step-by-step explanation:

Correct options are B, E. The point (0, -5) lies on the graph. The function is undefined for x = 1.

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.

In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The range is made up of all values that the function's output can take.

Given,

the function is y = 2x + 5 / x - 1

⇒ The value of x ≠ -1, as function can become undefined.

⇒ Horizontal Asymptote is 2

the value of y for x = 0,

y = 2x + 5 / x - 1

y = 2(0) + 5 / 0 - 1

Answer:

Simon's age is 18.

Step-by-step explanation:

Let Simons age be s and the age of each twin be t.

s + 2t = 48

s - t = 3

Subtract the second equation from the first:

s - s + 2t - (-t) = 45

2t + t = 45

3t = 45

t = 45/3 = 15.

Now we find Simon's age by plugging t = 15 in the second equation:

s - t = 3

s - 15 = 3

s = 3 + 15 = 18.

The scatter plot is the type of graph that is most frequently used to show the relationship between two numerical variables.

The graphs that show the association between two variables in a data set are called scatter plots. It shows data points on a two-dimensional plane or a Cartesian system.

The independent variable or attribute is represented by the X-axis, and the dependent variable is plotted using the Y-axis. To describe these charts, diagrams or graphs are usually employed. An XY graph, scatter chart, or scattergram are other names for a scatter plot. The scatter diagram plots numerical data pairings with one variable on each axis to show the relationship between them.

The derivation of the surface area of the cuboid,

A  =  2(ab² + bc² + ca²)

The surface area is a total outer layer of the three-dimensional figure. It is defined only for three dimensional shapes.

Suppose,

The length of  sides of the cuboid  are

a,

b,

c

Cuboid has 6 faces, and each face is like a rectangle,

So, If area of each face is calculated,

Then, the sum of area of each face will be equal to surface area of cuboid.

Surface Area =  A₁ + A₂ + A₃ + A₄ + A₅ + A₆

                      =  ab + bc + ca + ab + bc + ca

                      = 2( ab + bc + ca )

Answer:

To calculate the volume of a triangular pyramid, we can use the formula:

V = (1/3) * B * h

where V is the volume, B is the area of the base, and h is the height of the pyramid.

Since the base of the pyramid is a right-angled triangle, we can use the Pythagorean theorem to find the length of the other two sides, which are the legs of the triangle. The hypotenuse is 6 cm and the angle opposite to the hypotenuse is 30°, so we can use the sine function to find the length of the other leg:

sin(30) = opposite / hypotenuse

opposite = (sin(30) * hypotenuse) = (1/2 * 6) = 3

Now we can use the area formula for a right-angled triangle:

B = (1/2) * base * height = (1/2) * 3 * 6 = 9

To find the height of the pyramid, we can use the fact that all side faces form an angle of 60° with the base. We can use the sine function to find the height of the pyramid:

sin(60) = opposite / hypotenuse

opposite = (sin(60) * hypotenuse) = (√3/2 * 6) = 3√3 cm

Now we can substitute the values of B and h into the volume formula:

V = (1/3) * B * h = (1/3) * 9 * 3√3 = 3√3 cm³

So the exact volume of the triangular pyramid is 3√3 cm³.

The property of circumcircle is that the circumcircle always passes through all three vertices of a triangle.

A circumcircle is a circle that traverses a triangle's three vertices. It is also known as a "circumscribed circle." Every triangle's three vertices fall within the circumcircle.

The object's Center is defined as the point at where all of the triangle's perpendicular bisectors intersect. The circumcenter is the name of this Centre. The triangle's triangle might have its  Centre within or outside the circle. The radius of the circumcircle is also known as the triangle's circumradius. In a right triangle, the Centre is located precisely at the midpoint of the hypotenuse, and the hypotenuse is a diameter of the circumcircle.

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.

Range, which shows statistical dispersion, is the size of the smallest interval in descriptive statistics that encompasses all the data. It is best suited to capturing the dispersion of tiny data sets because it only depends on two observations.

[tex]-9y=-6x+216[/tex]        [divide both sides by -9]
