Answer:

8 b mod 12 is equal to 4.

Step-by-step explanation:

Use Dividend = Divisor × Quotient + Remainder

As b mod 12 = 5 (that is division of b by 12 gives a remainder of 5)

[tex]b=12k+5[/tex]

Here, k is any integer.

Multiply both sides of [tex]b=12k+5[/tex] by 8

[tex]8b=8(12k+5)\\8b=8(12k)+40[/tex]

write 40 in terms of 12

[tex]40=36+4=12(3)+4[/tex]

[tex]8b=8(12k)+12(3)+4\\8b=12(8k+3)+4[/tex]

Therefore,

8 b mod 12 is equal to 4.

Answer:

Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .

Answer:

13

Step-by-step explanation:

Answer: 13

Step-by-step explanation:

The distance formula between two points is:

[tex]c = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Our points are as follows -

[tex]x_2 = 0, x_1 = 5\\y_2 = 8, y_1 = -4[/tex]

If we plug them in:

[tex]c = \sqrt{(0 - 5)^2 + (8 - (-4))^2}[/tex]

All we need to do now is simplify

[tex]c = \sqrt{(-5)^2 + (12)^2}[/tex]

[tex]c = \sqrt{25 + 144}[/tex]

[tex]c = \sqrt{169} = 13[/tex]

Answer:

y = 7

Step-by-step explanation:

First, find the value of x.

[tex] (12x + 9) + (8x + 11) = 180 [/tex] (linear pair)

Solve for x

[tex] 12x + 9 + 8x + 11 = 180 [/tex]

Collect like terms

[tex] 12x + 8x + 9 + 11 = 180 [/tex]

[tex] 20x + 20 = 180 [/tex]

Subtract 20 from both sides

[tex] 20x + 20 - 20 = 180 - 20 [/tex]

[tex] 20x = 160 [/tex]

Divide both sides by 20

[tex] \frac{20x}{20} = \frac{160}{20} [/tex]

[tex] x = 8 [/tex]

Thus,

[tex] (12x + 9) = (14y + 7) [/tex] (vertical angles)

Plug in the value of x, and solve for y

[tex] 12(8) + 9 = 14y + 7 [/tex]

[tex] 96 + 9 = 14y + 7 [/tex]

[tex] 105 = 14y + 7 [/tex]

Subtract 7 from each side

[tex] 105 - 7 = 14y + 7 - 7 [/tex]

[tex] 98 = 14y [/tex]

Divide both sides by 14

[tex] \frac{98}{14} = \frac{14y}{14} [/tex]

[tex] 7 = y [/tex]

The features of the quadratic function f(x) = x^2 + 10x + 21  are Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5 so option (A) will be correct.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

For example 3x² + 6x + 8 = 0 here x has highest term as 2 and coefficient of x² is not zero.

The standard form of a quadratic equation is ax² + bx + c

The x vertex is given -b/2a

So,

x-vertex = -10/2 = -5

So y = (-5)² + 10(-5) + 21 = -4

So vertex is (-5, -4)

The Y-intercept is given as (0,y)

So,

y = 21

Therefore

y-intercept = (0,21)

the x-intercept is given as (x,0)

So,

x = -7 , -3

Therefore

x-intercepts = (-7,0) and (-3,0)

The Axis of symmetry is given by -b/2a

So,

⇒ -10/2 = -5

Hence "Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5".

Answer:

We can be sure that the actual distance lies between 11.65 and 11.74

Step-by-step explanation:

Here. we are told that the odometer measures to the nearest tenth.

The nearest tenth means to the nearest first digit after the decimal point

So the range of values we shall be writing will be the range that includes the smallest number that can be approximated to 11.7 and the largest number that can be approximated;

Thus, we have;

11.65 to 11.74

The reasoning is because the smallest number that can be approximated to 11.70 is 11.65 while the largest that can be approximated to 11.70 is 11.74. So the actual distance we need from the odometer is between 11.65 and 11.74

Answer:

10x-14=26

Step-by-step explanation:

x = 4

10 x 4 = 40

40 - 14 = 26

Answer:

26

Step-by-step explanation:

In order to answer this question, we must first find what x equals, so we need to solve for x in the equation 5x - 7 = 13:

5x - 7 = 13

     +7   +7

5x = 20

/5     /5

x = 4

Now, we plug in 4 for 'x' in the equation 10x - 14:

10(4) - 14 =

40 - 14 =

26

So, 10(4) - 14 = 26

Answer:

A. A rotation of 72º around the center, point D.

C. A reflection across line b through one vertex, the center d.

E. A reflection across line c, and the midpoint of the opposite side

Step-by-step explanation:

From Euclidean Geometry we get that sum of internal angles inside a polygon equals 360º and there is the following relationship in regular polygons:

[tex]\theta = \frac{360^{\circ}}{n}[/tex] (Eq. 1)

Where:

[tex]\theta[/tex] - Internal angle, measured in sexagesimal degrees.

[tex]n[/tex] - Number of sides, measured in centimeters.

If we know that [tex]n = 5[/tex], then internal angle of regular pentagon is:

[tex]\theta = \frac{360^{\circ}}{5}[/tex]

[tex]\theta = 72^{\circ}[/tex]

In consequence, rotating the regular pentagon 72º around the pentagon carries the figure onto itself due to angular symmetry. (Correct answer: A)

By adding any line passing the center of the regular pentagon (i.e. line cc', line bb'), which is collinear to any vertex and any point of the figure, we guarantee conditions of length symmetry so that reflection carries the figure onto itself. (Correct answers: C, E)
