A 9-sided shape is called a nonagon.

Therefore the answer is nonagon.

A nonagon is a polygon with nine sides and nine angles. A nonagon can be regular or irregular, depending on the lengths of its sides and angles. A regular nonagon has equal sides and angles, while an irregular nonagon has sides and angles of different lengths.

Nonagons are two-dimensional shapes, and they can be described by their number of sides, angles, and vertices. They are considered a type of polygon, which is a closed geometric figure that is made up of straight lines. In addition to nonagons, there are other types of polygons such as triangles, quadrilaterals, pentagons, hexagons, heptagons, and so on.

The system represents the cost of the beginner class will be $18 and the advanced class will be $24.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Both basic and expert magic lessons are available at Wacky Wizards. More than half as much is spent on the introductory class as there is on the advanced level. They made $390 last week by instructing 7 basic lessons and 11 advanced classes.

Let 'x' be the cost of beginner classes and 'y' be the cost of advanced classes. Then the equations are given as,

x = y / 2 + 6

y = 2x - 12             ...1

7x + 11y = 390      ...2

From equations 1 and 2, then we have

7x + 11(2x - 12) = 390

7x + 22x - 132 = 390

29x = 522

x = 18

Then the value of the variable 'y' is calculated as,

y = 2(18) - 12

y = 36 - 12

y = 24

The system represents the cost of the beginner class will be $18 and the advanced class will be $24.

Answer:

i depends on what the equation is.

The y - intercept of the graph, given the formula of 2 y - 5x = 16, is y - intercept : ( 0, 8)

To find the y - intercept, use the slope - intercept form of the equation of a line which is:

y = mx + b

m = slope

b = y - intercept

So first rewrite the formula given to look like the slope - intercept :

2 y - 5x = 16

2 y = 5x + 16

( 2 y = 5x + 16 ) / 2

y = 5/ 2 x + 8

The y- intercept is therefore 8. As a point on the graph, this is ( 0, 8 )

The sum of the first 11 terms of the geometric sequence aₙ = 2aⁿ - 1 with an initial value of a₁ = 1/8 is -10.71.

Therefore the answer is -10.71.

The geometric sequence aₙ = 2aⁿ - 1 with an initial value of a₁ = 1/8 represents the amount of money saved after n years of investing.

So sum of n terms

Sn = 2a - 1 + 2a² - 1 + ... + 2aⁿ - 1

Sn = 2( a + a² + ... + aⁿ) - n

The sum of the first n terms of a geometric sequence aₙ = arⁿ⁻¹ with first term a₁ and common ratio r is given by the formula:

Sn = a₁(1 - rⁿ)/ (1 - r), that is

[tex]S_{n} = a_{1}\frac{ (1 - r^n)}{1 - r}[/tex]

So a + a² + ... + aⁿ = a(1 - aⁿ)/ (1 - a)

Thus Sn = 2( a + a² + ... + aⁿ) - n

Sn = 2a(1 - aⁿ)/ (1 - a) - n

In this case, a₁ = a = 1/8 and n = 11

So the sum of the first 11 terms of the geometric sequence is:

Sn = 2×1/8×( 1 - (1/8)¹¹)/ (1 - 1/8) - 11

Sn = -10.71

Step-by-step explanation:

So I have 5 and 3 notes each

You need to use simultaneous equations to solve this problem since there are 2 variables.

50x + 100y = 550 (value of the notes x the number of each note)

x + y = 8 (the number of each note added).

Multiply the second equation by 50 so that it the x variables are the same in both equations. Thus, 50x + 50y = 400.

Subtract 50x + 50y = 400 from 50x + 100y = 550.

The subtraction results in 50y = 150.

Divide by 50. y = 3, so x must equal 5.

So I have 5 and 3 notes each

The midpoint for zero is (0,0).

The midpoint can be zero. This is dependent on the value of the two points. For two points on a number line on points with values -4, and 4, the midpoint is 0. And for two points such as (-2, 5), and (2, -5), the midpoint is equal to (0, 0).

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

A compass and straightedge setup can be used to locate the midpoint of the line segment they determine given two points of interest. By initially building a lens out of circular arcs with equal radii centered at the two endpoints and joining the cusps of the lens, one can determine the midpoint of a line segment immersed in a plane. The midpoint of the segment is then the place where the line joining the cusps intersects the segment.

See below

Step-by-step explanation:

You are supposed to find the volume.

To do this, find the volume of the green figure and blue(ish) figure separately and then add them together.

For volume, it is

length times width times height

[tex]l*w*h[/tex]

it doesn't matter what you say is length or height or whichever.

so let's do green

12 * 12 * 6

12*12 is gross aka 144

then 144*6 is... 864

The volume of the green figure is 864 cubic inches.

Now let's find the blue(ish) figure.

18 * 8 * 10

that equals 1,440 (calculator)

The volume of the blue(ish) figure is 1,440 cubic inches.

Now add the two volumes together.

1,440+864 = 2304

The distance of the boat is 191.2 miles, 12.8° and N12.8E from the original location.

To calculate the distance, direction angle, and bearing of the boat from its original location, we will need to use trigonometry to determine the final position of the boat.

a) The distance traveled in the eastward direction is 130 miles. Then, using the bearing of N38E, we can calculate the northward and eastward distances traveled in the second leg of the journey. The bearing of N38E can be thought of as an angle of 38 degrees measured clockwise from due east.

Using trigonometry to calculate the northward distance traveled, we have,

(72 miles) * (sin 38°)

= 36 miles

And the eastward distance traveled is (72 miles) * (cos 38°)

= 59.04 miles.

The final position of the boat is at a distance can be calculated by:

130 miles east + 59.04 miles east

= 189.04 miles east and 36 miles north from the original location.

b) To find the distance from the original location, we use the Pythagorean theorem,

d =  [tex]\sqrt{189.04^{2} +36^{2} }[/tex]

d = 191.2 miles

To find the direction angle, we use arctan(north/east) = arctan(36/189.04) = 12.8°

Bearing is the direction angle measured clockwise from north. So, bearing = 12.8°

Hence, the final position of the boat is 191.2 miles, 12.8°, and N12.8E from the original location.
