The mean height of the given sample of values is approximately 65.20.

The heights of the 15 students are as follows:

{59, 61, 62, 63, 63, 64, 65, 65, 66, 67, 67, 67, 67, 69, 73}

To find the mean (average) height of the given values, we need to add up all the heights and then divide the sum by the total number of heights:

59 + 61 + 62 + 63 + 63 + 64 + 65 + 65 + 66 + 67 + 67 + 67 + 67 + 69 + 73

Using the given information, the equation of the circle with center located at point (2 , 1) and passes through the point (6 , 4) is (x - 2)^2 + (y - 1)^2 = 25

Using the distance formula, get the radius of the circle by solving for the distance between the center (2 , 1) and the point (6 , 4).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(6 - 2)^2 + (4 - 1)^2

radius= √16 + 9

radius = √25

radius = 5

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (2 , 1)

r = 5

(x - 2)^2 + (y - 1)^2 = 5^2

The line which have a steeper slope is Line 1.

It is given in the question that the points on the line are given by:-

Line 1: (-9,-4) and (7,0)

We have to find which line has a steeper slope.

First we will find the slope of each line.

We know that slope of a line with points (a,b) and (c,d) is given by:-

(d-b)/(c-a)

Slope of Line 1:

(0-(-4))/(7-9) = 4/(-2) = -2 (we will take the absolute value)

Slope of Line 2:

(4-1)/(7-0) = 3/7

We know that greater the slope of the line means greater the steep of the line.

Answer:

Yes , Triangles are all tessellated. The triangle's three corners (A, B, and C) meet together to form a 180° angle, or a straight line, which is why the image is successful.

Is a triangle capable of tessellation?

To create a regular tessellation, it is necessary that the tiles may fill 360 degrees around a point (all the tiles regular polygons with same number of sides) Only 60 degree angle triangles, 90 degree squares, and 120 degree hexagons will work.

Every vertex, edge, and tile in a regular tesselation are identical.

However, there are semiregular tesselations that use more than one regular polygon, but since they must be able to fill 360 degrees around a point, it turns out that only the octagon (8 sides, 135 degrees) and dodecagon can be used as additional polygons (12sides, 150 deg).

Note that just these 5 tesselations can be utilized to fill the plane entirely with regular polygons.

Each vertex in the semiregular tessellations is the same.

Eight of them are (3,3,3,3,6), (3,3,3,4,4), (3,4,6,4), (3,6,3,6), (3,12,12), and (4,6,12). (4,8,8)

Time in flight = 22 - 18 = 4 minutes

Using translation concepts, the function g is given as follows:

g(x) = -|x - 4| + 1

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, we have that function g(x) is the function f(x) vertically compressed by a factor of 2, hence:

g(x) = 0.5f(x)

g(x) = 0.5(-2|x - 4| + 2)

g(x) = -|x - 4| + 1

Answer:  The claim is true

The proof is below

=====================================================

A = some nonzero rational number

B = some irrational number

Because value A is rational, this means A = p/q where p,q are nonzero integers.

Let's do a proof by contradiction. The claim is that A*B is irrational, but let's do the opposite and assume A*B is rational. We should get to a contradiction somewhere based on this assumption.

If A*B is rational, then A*B = r/s for some integers r and s

Then we can have the following steps

A*B = r/s

(p/q)*B = r/s

B = (r/s)*(q/p)

B = (rq)/(sp)

B = (some integer)/(some other nonzero integer)

B = some rational number

Recall we made B irrational. There's no way to have B rational and irrational at the same time. This is where the contradiction happens. This causes the original assumption of "A*B is rational" to be false. Therefore, the opposite must be the case and A*B has been proven to be irrational.

Therefore, the product of a rational number and an irrational number is irrational.

Example:

5 is rational

sqrt(3) is irrational

On the model, we have the following representations

When represented as an equation, we have the following equation

So, we have

2 = -8 * -x

Evaluate the product in the above equation

So, we have

2 = 8x

Divide both sides of the above equation by 8

So, we have

1/4 = x

Rewrite the above expression as

an=a1+d(n−1)  is the explicit and a recursive formula for each sequence .

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.
