A regular hexagon can be divided into six equilateral triangles by drawing lines from the center of the hexagon to each of its vertices.

Each of these equilateral triangles has an area that is one-sixth of the total area of the regular hexagon.

When the midpoints of the sides of the regular hexagon are joined to form a smaller regular hexagon, it can be seen that the smaller hexagon is made up of six equilateral triangles, each of which has half the area of the equilateral triangles in the larger hexagon. This is because the sides of the smaller hexagon are half the length of the sides of the larger hexagon.

Therefore, the fraction of the area of the larger hexagon that is enclosed by the smaller hexagon is:

[tex]6 * (1/2)^2 = 6 * 1/4 = 3/2[/tex]

This means that the smaller hexagon encloses 3/2 of the area of the larger hexagon.

The required equation of the line is y = 5x + 3.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

From the given table we have slope(m) = (3 + 2)/(0 + 1) = 5/1 = 5.

Now, - 2 = 5(-1) + b.

- 2 = - 5 + b.

b = 3.

Therefore, y = 5x + 3 is the required equation of the line.

The average of any two real numbers is not greater than both of the two numbers, and is less than or equal to at least one of the two numbers.

The proof by contradiction of the theorem begins by assuming the opposite of the theorem, that the average of any two real numbers is greater than both of the two numbers. This can be expressed mathematically as follows:

Let a and b be two real numbers.

Average of a and b = (a + b)/2

Assume that (a + b)/2 > a and (a + b)/2 > b

This can be rewritten as

(a + b)/2 - a > 0  and  (a + b)/2 - b > 0

Subtracting a from both sides of the first equation and subtracting b from both sides of the second equation yields

b - a > 0  and  a - b > 0

Since b - a and a - b are both positive, the two equations cannot be true simultaneously. This is a contradiction and therefore our initial assumption must be false. Therefore, the average of any two real numbers is not greater than both of the two numbers, and is less than or equal to at least one of the two numbers.

Answer:

#9       (x, y) = (6, 32)

#10      The meaning of the solution is that if you buy 6 kites from either store, the total cost will be the same and is $32

Step-by-step explanation:

The legend is missing so by looking at the graph alone we are unable to determine which color line corresponds to which kind of kite(Kites-R-Fun or Windy Kites)

However the associated table will help us determine this

The linear equation for a line is expressed as

y = mx + c

where m = slope of the line and b = y-intercept which is the y-value for the point where the line crosses the y-axis(at x = 0)

Slope m = rise/run = Δy/Δx = (y2 - y1)/(x2 - x1) for any two points (x1, y1) and (x2, y2) on the line

Let's take the two  x values as x1=0 and x2=1 and use the table

For Kites-R Fun
x1 = 0 ==> y1 = 8. This is also the y-intercept, b
We see that the red line corresponds to x = 0, y = 8

x2 = 1 ==> y2 = 12

y2 - y1 = rise = Δy =12 - 8 = 4

x2 -   x1 = Δx = 1 - 0 =1

Slope m = 4/1 = 4

Equation of Kites-R Fun is 4x + 8

For Windy Kites

x1 = 0 ==> y1 = 20
y-intercept = 20 or b = 20

x2 = 1 ==> y2 = 22

Rise = Δy =22 - 20 = 2
Run = Δx = 1 - 0 = 1
Slope = m, b = 20

Equation of blue line is
y = 2x + 20

The two equations are:
y = 4x + 8
y = 2x + 20

Equating right sides:
4x + 8 = 2x + 20

Move 2x to the left side and 8 to the right side:

4x + 2x + 8 - 8 = 2x - 2x + 20 -8

2x = 12

x = 6

For x = 6 the costs are the same

Plugging x = 6into equation y = 4x + 8:
y = 4(6) + 8 = 24 + 8 = 32

So the solution set is
(6, 32)

Looking at the graph we see the two lines intersect at this point
(Heck, we could have avoided all this work and just looked at the graph but I don't expect that was what they intended. You can add this as a side note)

On the second part

For Kites-R-US, each kite costs $4
The meaning of the solution is that if you buy 6 kites from either store, the total cost will be the same.

Answer:

Below

Step-by-step explanation:

y = 1/2 x + 1

y = 3/2x + 4        Use first equation to sub in for y

1/2 x + 1  = 3/2 x + 4

-3 = x       then use this value in one of the equations to calc  y

y = 1/2 x + 1

y = 1/2 (-3) + 1 =  - 1/2

Sigma notation for the sum is  ∑5ⁿ⁻⁴ (where n = 1 to 5)

Sigma notation is the most easiest way of writing a very large sum of elements of a sequence in a simple manner.

∑ is the symbol that is pronounced as "sigma".

"i" or "n" is called the index of summation

Given sum,

1/125 + 1/25 + 1/5 + 1 + 5

First term a is 1/125

Common ratio r = 1/25/1/125 = 5

Sequence can be written as

aⁿ = a.rⁿ⁻¹

aⁿ = 1/125 . 5ⁿ⁻¹

aⁿ = 5⁻³. 5ⁿ⁻¹

aⁿ = 5ⁿ⁻⁴

The amount budgeted for Auto expenses is $100,000 * 14% = $14,000.

Step-by-step explanation:

If Logan has given out a total of 6.65 in nickels and dimes , then the number of dimes he has given out is  38 .

Let the number of nickels that Logan gave out be = n , and

the number of dimes that Logan gave out be =  d ;

From the information , we know that Logan gave out 50% more nickels than dimes,

that means ; n = d + 0.5d = 1.5d   ...equation(1) ;

We also know that the total amount given out in nickels and dimes is $6.65, and each nickel is worth of  $0.05 and each dime is worth of  $0.10,

So ,  n×0.05 + d×0.10 = 6.65 ;

Substituting the expression for n from the first equation into the second:

⇒ (1.5d)×0.05 + d×0.10 = 6.65 ;

Expanding and solving for d ;

we get ;

⇒ 0.075d + 0.10d = 6.65 ;

⇒ 0.175d = 6.65 ;

⇒ d = 6.65/0.175 = 38 ;

Therefore ,  Logan gave out 38 dimes.

Answer: function A is linear

Step-by-step explanation:

The central angle corresponds to an arc length of 2 yd and a radius of 7 yd is 0.09 pi

Central angle is the angle subtended by an arc of a circle at the center of a circle. The radius vectors form the arms of the central angle. In other words, it is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle. When these two points are joined they form an arc. Central angle is the angle subtended by this arc at the center of the circle

The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. A circle can be divided into sectors by using the central angle. An excellent illustration of a central angle is a pizza slice. A pie chart is made up of several sectors and is useful for representing various amounts.

The volume of the solid is approximately 807.08 cubic units.

To determine the volume of the solid, we can use the method of cylindrical shells.

Imagine taking a slice of the solid parallel to the base, with the cross-sectional area being a square of side length x (where x is a function of the height). The volume of this slice is the product of the square area and the height. The height of the slice is equal to the difference in the radii of two consecutive circular cross sections.

The radius of the larger circular cross-section can be found using the Pythagorean theorem, which states that the square of the hypotenuse (the radius) is equal to the sum of the squares of the other two sides (the height and half the side length of the square). Thus, we have:

r² = x² + (15-x)²

Solving for x, we get:

x = 15 * √(1 - (r/15)²)

The volume of the slice is then given by:

V = x² * (15 - x)

To find the total volume of the solid, we integrate this expression with respect to r from 0 to 15. The result is approximately 807.08 cubic units.

Answer:

To write equivalent fractions with a common denominator, we need to find the least common multiple (LCM) of the denominators of the fractions and then write each fraction with the LCM as the denominator. Here's a step by step guide:

1. To find the LCM of 3 and 6, we list the multiples of each number and find the smallest one that is common to both:

Multiples of 3: 3, 6, 9, 12, 15, 18, ...

Multiples of 6: 6, 12, 18, 24, 30, 36, ...

The LCM of 3 and 6 is 6, so we write 2/3 and 3/6 with 6 as the denominator:

2/3 = 4/6 and 3/6 = 1/2

2. To find the LCM of 4 and 12, we list the multiples of each number and find the smallest one that is common to both:

Multiples of 4: 4, 8, 12, 16, 20, 24, ...

Multiples of 12: 12, 24, 36, 48, 60, 72, ...

The LCM of 4 and 12 is 12, so we write 3/4 and 5/12 with 12 as the denominator:

3/4 = 9/12 and 5/12 = 5/12

3. To find the LCM of 5 and 10, we list the multiples of each number and find the smallest one that is common to both:

Multiples of 5: 5, 10, 15, 20, 25, 30, ...

Multiples of 10: 10, 20, 30, 40, 50, 60, ...

The LCM of 5 and 10 is 10, so we write 3/5 and 7/10 with 10 as the denominator:

3/5 = 6/10 and 7/10 = 7/10

You can use this process to find the LCM and write equivalent fractions with a common denominator for the rest of the problems.
