yan [13]

Answer:

They use Phylosophy as a means of Spiritual cleansing.

The Pythagorean theorem.

The Demand that members must live in strict secrecy and loyalty.

The appeal to certain symbols like Tetraktys etc.

They believe the soul is destined for heaven,where it will United with the Divine.

They believe that reality including music and astronomy when at their repeat level are Mathematical in nature.

Step-by-step explanation: The Pythagorean brotherhood is believed to have originated from Sounthern Italian city known as Croton. It was started by a man called Pythagoras from Samos Greece, he is a controversial phylosopher.

The Pythagorean brotherhood formulated one the most widely used Theorems in Geometry which states that THE SQUARE OF THE HYPTHEMUS OF A RIGHT ANGLED TRIANGLE IS EQUAL TO THE SQUARE OF THE OPPOSITE AND THE BASE.

The vertex of this parabola is at (3,-2). when the x-value is 4, the y-value is 3. whatis the coefficient of the squared express
zubka84 [21]

Answer:

<em>The coefficient of the squared expression in the parabolas equation will be 5.</em>

Step-by-step explanation:

<u>The vertex form of parabola</u> is:  y=a(x-h)^2 +k , where (h,k) is the vertex point and a is the coefficient of x^2 term.

The vertex is given as (3,-2). That means, h=3 and k=-2

So, the vertex form will be:  y=a(x-3)^2-2

Given that, when the x-value is 4, the y-value is 3. So, plugging these values into the above equation, we will get.....

3=a(4-3)^2-2\\ \\ 3=a(1)^2-2\\ \\ a=3+2=5

Thus, the coefficient of the squared expression in the parabolas equation will be 5.

Answer:

(A) -3 ≤ x ≤ 1

Step-by-step explanation:

The given function is presented as follows;

h(x) = x² - 1

From the given function, the coefficient of the quadratic term is positive, and therefore, the function is U shaped and has a minimum value, with the slope on the interval to the left of <em>h</em> having a negative rate of change;

The minimum value of h(x) is found as follows;

At the minimum of h(x), h'(x) = d(h(x)/dx = d(x² - 1)/dx = 2·x = 0

∴ x = 0/2 = 0 at the minimum

Therefore, the function is symmetrical about the point where x = 0

The average rate of change over an interval is given by the change in 'y' and x-values over the end-point in the interval, which is the slope of a straight line drawn between the points

The average rate of change will be negative where the y-value of the left boundary of the interval is higher than the y-value of the right boundary of the interval, such that the line formed by joining the endpoints of the interval slope downwards from left to right

The distance from the x-value of left boundary of the interval that would have a negative slope from x = 0 will be more than the distance of the x-value of the right boundary of the interval

Therefore, the interval over which <em>h</em> has a negative rate of change is -3 ≤ x ≤ 1

The quotient of (x4 + 5x3 – 3x – 15) and a polynomial is (x3 – 3). What is the polynomial?
rewona [7]

Answer:

  (x +5)

Step-by-step explanation:

The problem statement is telling you that one factor of (x⁴ +5x³ -3x -15) is (x³ -3). It is asking for the other factor. Clearly, you can find the other factor by dividing the polynomial by the given factor.

That is ...

  (x⁴ +5x³ -3x -15) / (x³ -3) = (x +5)

so ...

  (x⁴ +5x³ -3x -15) / (x +5) = (x³ -3)

The divisor of interest is (x +5).
