The magnitude of rotational symmetry of the regular octagon below the marked point is 45°, so option A is correct.

Eight sides, eight internal angles, and eight vertices are the characteristics of an octagon. An octagon is referred to as being regular if all of its sides and angles have the same measurements.

Given:

From the figure, the lengths of the side of the octagon are equal,

So the angle will also be equal,

And we know that octagon has 8 interior angles and their sum is 360 degrees.

Now for measure of one angle = 360° / 8 = 45°,

Therefore, the magnitude of rotational symmetry of the regular octagon below the marked point is 45°.

Answer:

The square root is the inverse operation to the power of 2, so that whenever you take a number and perform both actions on it, you get the same number back.

Sample Answer:  Squaring and square root are inverses, so one should "undo" the other. That is, squaring the square root of a number results in the number. Using the power of a power rule, you multiply the exponents. Since a number to the first power is itself, the product of the exponents must equal 1. This means that the power of the square root must be the reciprocal of 2, or one half.

Answer:

x=8

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh  where b is the base and h is the height

16 = 1/2 (4) x

16 =2x

Divide each side by 2

16/2 = 2x/2

8 =x

The height is 8 units

Answer:

Because 1/9 is a fraction with integers meaning it is a fraction with whole numbers.

Step-by-step explanation:

Any number that can be written as a fraction with integers is called a rational number. For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)

Answer:

Surface area of the figure = 1672 [tex]cm^{2}[/tex]

Step-by-step explanation:

Surface area of the figure = surface area of the prism + surface area of the 3 cubes

The surface area of the rectangular prism = sum of the area of its individual sides

                                             = 2(26 x 10) + 2(10 x 10) + 2(26 x 10)

                                             = 520 + 200 + 520

The surface area of the rectangular prism = 1240 [tex]cm^{2}[/tex]

Surface area of one of the cubes = 5(6 x 6)

                                                      = 180 [tex]cm^{2}[/tex]

The surface area of the 3 cubes = 3 x 180

                                                     = 540 [tex]cm^{2}[/tex]

Thus, the surfaces of the cubes on the prism covers a total area of 108 [tex]cm^{2}[/tex].

So that;

The surface area of the figure = (1240 - 108) + 540

                                               = 1132 + 540

                                                = 1672 [tex]cm^{2}[/tex]

Answer:

B. X= 5 + 3i

5 + 3i

Step-by-step explanation:

We are given the quadratic equation

x² - 10x = -34

x² - 10x + 34 = 0

Using Almighty formula

x = -b ± √b² - 4ac/2a

When given equation: ax² + bx + c

Where: a = 1, b = -10 , c = 34

x = -10 ± √-10² - 4 × 1 × 34/2 × 1

x = 10 ± √100 - 136/2

x = 10 ± √-36 /2

x = 10/2 ±. √-36/2

x = 5 ± 6i /2

x = 5 ± 3i

Hence: the roots of the equation are:

x = 5 - 3i , x = 5 + 3i

From the question we are told that:

Seventh term [tex]7th= 21[/tex]

Common difference [tex]d= 5[/tex]

Generally Equation for seventh term

[tex]7th=a+(7-1)d[/tex]

Therefore the  First Term is given as

[tex]a=7th-(7-1)d[/tex]

[tex]a=21-6*5\\a=-9[/tex]

Generally the equation for 9th term is mathematically given by

[tex]9th=a+8d[/tex]

[tex]9th=-9+8(5)[/tex]

[tex]9th=31[/tex]

Answer:

Out of the ten spins seven landed on blue.

I hope this helps :)

Answer:

The fraction that would represent the part of Pedro's spins that were blue would be [tex]\frac{7}{10}[/tex].

Step-by-step explanation:

In a fraction, there is a numerator and a denominator. In order to get a fraction that would represent the part of Pedro's spins that were blue, you need to put the number of times the pointer landed on blue as a numerator and the total number of spins as the denominator. Therefore a fraction that would represent the part of Pedro's spins that were blue would be [tex]\frac{7}{10}[/tex].

Answer:

The ? represents the number 38 because the average rate of change on every interval of the function is 3

Step-by-step explanation:

Firstly, we calculate the average rate of change over a function can be calculated using the formula below;

f(b) -f(a)/(b-a)

Now, over the interval [-2,2]

we have;

(17-5)/(2/(-2)) = 12/4 = 3

This is expected to be the blanket average rate of change

Thus, we have it that over the interval [5,9]; we have;

3 = f(b) - 26/9-5

3 = f(b) - 26/4

4(3) = f(b) - 26

12 = f(b) - 26

f(b) = 12 + 26

f(b) = 38

At x = 3, y = -2(3) + 4 = -2

The output is -2 when the input is 3.

Answer: [tex]371.8\ \text{Pounds}[/tex]

Step-by-step explanation:

Given

Dimensions of rectangular granite countertop is [tex]72\times 42\times 1.25\ in.^3[/tex]

Density of granite is [tex]\rho=170\ \text{Pounds per cubic ft}[/tex]

Volume of granite countertop

[tex]\Rightarrow V=72\times 42\times 1.25\\\Rightarrow V=3780\ in.^3[/tex]

We know, 1 ft=12 inch

[tex]\therefore V=2.187\ cm^3[/tex]

Weight of granite

[tex]\Rightarrow m=\rho \times V\\\Rightarrow m=170\times 2.1875\\\Rightarrow m=371.8\ \text{Pounds}[/tex]
