The trinomial( consists three different terms), 2x² + 13x + 6, has a linear factor of (x + 6) and the linear factor of (x+6) is equals to a (2x+1).

We have, a trinomial 2x² + 13x + 6 has a linear factor of x + 6 and we have to determine that linear factor of (x + 6). To determine the linear factor of (x + 6) either dividing the trinomial by (x+6) or factorization of this trinomial. Factoring a trinomial means expanding an equation into the product of two or more binomials. Here, middle term of trinomial, b = 13

last term, c = 6

Using spliting middle term method for factorization, 2x²+ 13x + 6 = 2x² + 12x + x + 6

=> 2x² + 13x + 6 = 2x( x + 6) + 1(x + 6 )

Common factor from binomials,

=> 2x² + 13x + 6 = (x + 6)(2x + 1)

Thus, the linear factor of (x+6) is (2x +1).

Answer:

function not defined for x = 2

Step-by-step explanation:

The open circle at x = 2 shows that the function is not defined for x = 2.

The first five terms of the sequence given the definition are -1, 0, 1, 2 and 3

To find the first five terms of the sequence {an}, we can use the recursive definition of the sequence and compute each term one by one:

a1 = -1

For n = 2, we have:

a2 = a1 + (-1)² = -1 + 1 = 0

For n = 3, we have:

a3 = a2 + (-1)³ = 0 - (-1) = 1

For n = 4, we have:

a4 = a3 + (-1)⁴ = 1 + 1 = 2

For n = 5, we have:

a5 = a4 + (-1)⁵ = 2 - (-1) = 3

Therefore, the first five terms of the sequence {an} are:

a1 = -1

a2 = 0

a3 = 1

a4 = 2

a5 = 3

The coordinates of the reflected quadrilateral A'B'C'D can be determined by reflecting the coordinates of the original quadrilateral ABCD across the x-axis.

A reflection across the x-axis is a transformation that flips an object across the line x = 0. This means that the points in the object will be reflected across the x-axis. The coordinates of the reflected quadrilateral A'B'C'D can be determined by reflecting the coordinates of the original quadrilateral ABCD across the x-axis .Let us consider the original quadrilateral, ABCD, with coordinates A(x1, y1), B(x2, y2), C(x3, y3) and D(x4, y4). Then, the coordinates of the reflected quadrilateral A'B'C'D are A'(-x1, y1), B'(-x2, y2), C'(-x3, y3) and D'(-x4, y4).For example, if the coordinates of quadrilateral ABCD are A(3, 5), B(7, 6), C(4, 8) and D(9, 2), then the coordinates of the reflected quadrilateral A'B'C'D will be A'(-3, 5), B'(-7, 6), C'(-4, 8) and D'(-9, 2).Therefore, the coordinates of the reflected quadrilateral A'B'C'D can be determined by reflecting the coordinates of the original quadrilateral ABCD across the x-axis.

Step-by-step explanation:

We can Frame an equation, taking the previous temperature as "x" and adding 2 by every hour.

Previous Temprature + 2 = New Temprature

Therefore by this equation:

at 8AM , the Temperature is -5 + 2 = -3*c
at 9AM , the Temperature is -3 + 2 = -1*c
at 10 AM, the Temperature is -1 + 2 = 1*c


Therefore at 11AM , the Temperature will be 1 + 2 = 3*c

Hope it helps.

The solution of the system of equation is (3, 5) and (–4, 12) [option A]

The given system of equations is:

x + y = 8

y = x² – 4

To solve for x and y, we can substitute the second equation into the first equation for y:

x + (x² - 4) = 8

Simplifying, we get:

x² + x - 12 = 0

Now we can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / 2a

where a = 1, b = 1, and c = -12

x = (-1 ± √(1² - 4(1)(-12))) / 2(1)

x = (-1 ± √(1 + 48)) / 2

x = (-1 ± 7) / 2

Solving for x gives us two possible values: x = 3 or x = -4.

To find the corresponding values of y for each value of x, we can substitute them into either of the original equations. Using y = x² - 4:

When x = 3, y = 3² - 4 = 5

When x = -4, y = (-4)² - 4 = 12

Therefore, the solution to the system of equations is (3, 5) and (-4, 12), which is answer choice (a).

The volume of water that can be enclosed in the outside layer of the glass is 4πr² x 0.25 cm.

Volume is a measure of the quantity or amount of space an object occupies. It is measured in cubic units, such as cubic meters, cubic centimeters, and cubic feet. Volume is also used to measure the amount of liquid or gas in a container. Volume is an important concept in mathematics, science, engineering, and other subject areas. It can be used to calculate the mass, weight, density, and other physical properties of a substance or object.

The volume of water that can be enclosed in the outside layer of the glass is equal to the volume of the plastic material that encloses the glass. Since the thickness of the plastic is 0.25 cm, the volume of the plastic material is equal to its surface area multiplied by the thickness. The surface area of the glass can be calculated using the equation 4πr², where r is the radius of the glass.

Therefore, the volume of water that can be enclosed in the outside layer of the glass is 4πr² x 0.25 cm. This is equal to the volume of the plastic material that encloses the glass. It should be noted that this volume of water is only an approximation since other factors such as the porosity of the plastic material must be taken into account.

The area of the regular 12-sided polygon with a radius of 4 units is approximately 31.28 square units.

What is polygon?

A polygon is a two-dimensional geometric shape that is made up of straight lines connecting a sequence of points, which are called vertices.

To find the area of a regular polygon with 12 sides and a radius of 4 units, we can use the formula:

Area = (1/2) * perimeter * apothem

The perimeter of the polygon can be found by multiplying the number of sides by the length of each side. Since the polygon is regular, all sides are of equal length. Let's call this length "s".

s = 2 * r * sin(π/n) where r is the radius and n is the number of sides

s = 2 * 4 * sin(π/12)

s = 1.38 (rounded to two decimal places)

The perimeter of the polygon is:

P = 12 * s

P = 16.56 (rounded to two decimal places)

To find the apothem, we can use the formula:

apothem = r * cos(π/n)

apothem = 4 * cos(π/12)

apothem = 3.77 (rounded to two decimal places)

Now we can calculate the area of the polygon:

Area = (1/2) * P * apothem

Area = (1/2) * 16.56 * 3.77

Area = 31.28 square units (rounded to two decimal places)

Therefore, the area of the regular 12-sided polygon with a radius of 4 units is approximately 31.28 square units.

Since M and N have the same coordinates, we know that AC and BD intersect at the point (1,3). The coordinates of the intersection point are (1,3).

What is rhombus?

A rhombus is a special type of parallelogram in which all four sides are of equal length. Equivalently, a rhombus is a quadrilateral with four sides of equal length.

Since ABCD is a rhombus, its diagonals AC and BD are perpendicular bisectors of each other, and they intersect at their mutual midpoint M.

The midpoint M of AC is the average of the coordinates of A and C, namely:

M = ((-1+3)/2, (2+4)/2) = (1, 3)

Similarly, the midpoint of BD is the average of the coordinates of B and D. Since we don't know the coordinates of B and D, we need to find them first.

The other two vertices of the rhombus are obtained by reflecting A and C about the midpoint M, since opposite sides of a rhombus are parallel and equal in length. To do this, we subtract the coordinates of M from those of A and C, and then add them to M:

B = 2M - A = 2(1,3) - (-1,2) = (3,4)

D = 2M - C = 2(1,3) - (3,4) = (-1,2)

Now we can find the midpoint of BD:

N = ((3-1)/2, (4+2)/2) = (1, 3)

Since M and N have the same coordinates, we know that AC and BD intersect at the point (1,3). Therefore, the coordinates of the intersection point are (1,3).

Step-by-step explanation:

The equation of line is y = -3x + 2

An equation for two variables is a mathematical statement that relates two variables, typically represented by x and y, using mathematical symbols and operations such as addition, subtraction, multiplication, and division.

To find the equation of the line that passes through the given points (2, -4), (3, -7), (4, -10), and (5, -13), we can use the slope-intercept form of the equation of a line:

y = mx + b, where slope of the line is m and y-intercept is b.

First, let's find the slope of the line using two of the points, say (2, -4) and (3, -7). The slope, m, is given by:

m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

= (-7 - (-4)) / (3 - 2)

= -3

we know the slope, we can use one of the points, say (2, -4), and the slope to find the y-intercept, b. Use the slope intercept to form the equation of a line:

y = mx + b, and substitute in the slope and coordinates of one of the points:

-4 = (-3)(2) + b

Simplifying this equation, we get:

b = -4 + 6

= 2

Answer: x = 24

Step-by-step explanation:

To solve for x, we need to simplify the left side of the equation first by combining like terms:

4x - 2 + 3x + 14 = 180

7x + 12 = 180

Next, we will isolate the variable by subtracting 12 from both sides:

7x + 12 - 12 = 180 - 12

7x = 168

Finally, we will solve for x by dividing both sides by 7:

7x/7 = 168/7

x = 24

Therefore, the solution to the equation 4x-2+3x+14=180 is x = 24.

The length of each side of the hexagon is 13 units long, which is equal to length of the park.

In order to determine the length of every side of the hexagon, it is necessary to compute the distance between each pair of neighboring vertices.

This can be accomplished by employing the distance formula, which is represented as follows:

d = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² ).

To facilitate the process, we will designate the vertices as A, B, C, D, E, and F in sequence, with A being the vertex at the top.

Then, the length of side AB is calculated as follows:

|AB| = √((38.5-26.5)² + (7-12)²)

|AB| = √((12)² + (-5)²)

|AB| = √(144 + 25)

|AB| = √169

|AB| = 13

Similarly, we can calculate the length of each side:

|BC| = √( (26.5-38.5)² + (2-7)² ) = 13

|CD| = √( (13.5-26.5)² + (2-2)² ) = 13

|DE| = √( (1.5-13.5)² + (7-2)² ) = 13

|EF| = √( (13.5-1.5)² + (12-7)² ) = 13

Answer:

13 units

Step-by-step explanation:

d^2 = (x2 – x1)^2 + (y^2 – y^1)^2

Now we calculate the distance between 2 points:

d^2 = (6.5 – (-6.5))^2 + (5 – 5)^2

d^2 = 169

d = 13

Therefore the length of each side of the park is 13 units.

Answer: y=28

Step-by-step explanation:

The coordinates of the foci of the ellipse given by 4x² + y² = 64 are (0, 0).

To find the coordinates of the foci of the ellipse given by the equation 4x² + y² = 64, we can compare it to the standard form of an ellipse:

(x²/a²) + (y²/b²) = 1

In this case, the equation 4x² + y² = 64 can be rewritten as:

x²/(8²) + y²/(8²) = 1

Comparing the equation to the standard form, we find that a = 8 and b = 8. The foci of the ellipse can be calculated using the formula:

c = sqrt(a² - b²)

For our ellipse, c = sqrt(8² - 8²) = sqrt(64 - 64) = 0.

Since c = 0, the foci coincide with the center of the ellipse. Thus, the coordinates of the foci are the same as the center of the ellipse.

Therefore, the coordinates of the foci of the ellipse given by 4x² + y² = 64 are (0, 0).
