Answer:

10

Step-by-step explanation:

The value for x is 10; the perimeter is 56 inches; a possible area the area is 7 square feet (option c); and a possible perimeter is 25 m (option a).

To find the correct value for x, let's replace the possible values and verify if the total is >11.

2x + 9

(2 x 0) + 9 = 0 + 9 = 9

(2 x -5) + 9 = -10 + 9 = 1

(2 x 10) + 9 =20 + 9 = 29

(2 x -8) + 9 = -16 + 9 = 7

Based on this, the correct value for x is 10

The perimeter of an octagon can be calculated using this formula:

8 x lengh of one side

8 x 7 inches =  56 inches

The area of a shape is calculated by multiplying side x side. Due to this, areas are always expressed using square meters, square feet, square kilometers, etc. Based on this principle, a possible area is 7 square feet (option c).

The perimeter is found by adding the lengh of all the sides in a shape. Due to this, it is expected a perimeter is expressed in meters, kilometers, centimeters, etc. Based on this a possible perimeter is 25 m (option a).

Answer:

Radius = 25.5 units

Diameter = 51 units

Step-by-step explanation:

r = radius of circle

d = Diameter of circle

  = \(2r\)

Circumference of circle = \(2\pi r\)

Substitute the provided value of the circumference:

                               \(51\pi = 2\pi r\)

r is to be isolated and made the subject of the formula:

                                 \(r = \frac{51\pi}{2\pi}\)

\(\pi\) in the numerator and denominator cancel each other outcompletely:

                                 \(r = \frac{51}{2}\)

                          ∴r = radius of circle = 25.5 units

This also means that:

\(d = 2r\)

\(d = 2(25.5)\)

∴d = Diameter of the circle = 51 units

Answer:

y = 22

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the angles in the lower triangle and equate to 180°

∠ 1 + 19° + 41° = 180°

∠ 1 + 60° = 180° ( subtract 60° from both sides )

∠ 1 = 120°

∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so

∠ 2 = 120°

Sum the angles in the upper triangle and equate to 180

y + 120 + 38 = 180

y + 158 = 180 ( subtract 158 from both sides )

y = 22

The graph of the equation y=2x+1 shows a straight line, or it is a linear equation. When the value of x rises, eventually the value of y rises by twice the rise in x plus one. With a ruler and the specified amount as the starting point, draw a vertical line. From the line across to the -axis, create a horizontal line using a ruler. Look at the value on the -axis.

There are three fundamental ways to graph linear functions. The initial method involves charting points and then tracing a line through them. The second is by using the slope and y-intercept. The identity function f(x)=x is transformed as the third method.

Answer:

(2x+1)^2 or 4x^2+4x+1

Step-by-step explanation:

I'm going to assume you need to find f(g(x)) when f(x)=x^2 and g(x)=2x+1

You first need to find g(x) which is 2x+1

You then take the f(x) function and replace x with 2x+1

This means our new equation is

(2x+1)^2

Your teacher may or may not want you stop here, really only you know the answer to that

But if we expand this we'll find that (2x+1)^2=4x^2+4x+1

The equivalent expression of (f o g) is 4x² + 4x + 1.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Two functions are given.

f(x) = x²

g(x) - 2x + 1

Now,

(f o g)(x) = f(g(x))

g(x) - 2x + 1

So,

f(g(x)) = f(2x + 1)

Now,

f(2x + 1)

= (2x + 1)²

= 4x² + 4x + 1

Thus,

The expression of (f o g) is 4x² + 4x + 1.

Using the provided quadratic expression and factorizing it, The answer is  x = ± √6.4 or x = ± 2.51 and  x = 1 or x = -2.5 .

An equation is a statement of equality between two expressions. It typically includes numbers and mathematical operations such as addition, subtraction, multiplication, and division. For example, the equation 2x + 3 = 7 is a statement that the value of the expression 2x + 3 is equal to the value of 7. Equations can also include variables, which represent unknown values that can be solved for.

Roots of an equation are the values of the variable that make the equation true. For example, the roots of the equation x^2 + 2x - 3 = 0 are -1 and 3, because (-1)^2 + 2(-1) - 3 = 0 and 3^2 + 2(3) - 3 = 0. In general, finding the roots of an equation can be a difficult task and may require the use of mathematical techniques such as factoring, graphing, or numerical methods. Roots are also known as solutions or zeroes of an equation. They can be found by setting the equation equal to zero and solving for the variable.

(4+5x²-36) = 0 or (2x²+9x-5) = 0

Solving the first factor:

4+5x²-36 = 0

5x²-32 = 0

5x² = 32

x² = 6.4

x = ± √6.4

x = ± 2.51 or -2.51

Solving the second factor:

2x²+9x-5 = 0

x²+4.5x-2.5 = 0

(x-1)(x+2.5) = 0

The coordinates of all the vertices of the prism are:

A(0, 0, 0)

B(2, 0, 0)

C(0, 4, 0)

D(0, 0, 3)

E(2, 0, 3)

F(0, 4, 3)

G(2, 4, 3)

H(2, 4, 0)

A three-dimensional solid object called a prism has two identical sides. It consists of equal cross-sections, flat faces, and similar bases. Without bases, the prism's sides are parallelograms or rectangles. And any n-sided polygon, including a triangle, square, rectangle, or other, could serve as the prism's basis.

Let's first identify the vertices of one of the triangular bases, and then use those vertices to find the coordinates of the corresponding vertices on the other base.

The vertices of the first triangular base are:

A(0, 0, 0)

B(2, 0, 0)

C(0, 4, 0)

The vertices of the second triangular base are found by adding the height of the prism to the z-coordinates of the first base:

D(0, 0, 3)

E(2, 0, 3)

F(0, 4, 3)

Therefore, the coordinates of all the vertices of the prism are:

A(0, 0, 0)

B(2, 0, 0)

C(0, 4, 0)

D(0, 0, 3)

E(2, 0, 3)

F(0, 4, 3)

G(2, 4, 3)

H(2, 4, 0)

Note that we can obtain the coordinates of G and H by adding the height of the prism to the z-coordinates of B and C, respectively.
