What is the rule for an exponential graph?

The total number of people are 1064 to whom the single cell phone towers are assigned in a particular city.

In a graphical or tabular format, a frequency distribution displays the frequency of repeated entries. It provides a visual representation of the frequency of various items or counts their occurrences.

There are total of 44,700 people in the city and total of 42 cell ,

so to find out the number of people using single cell tower is,

Number of people on single cell tower = 44700/42

=1064.285 ≈ 1064 people

The gathered information is arranged in tables using the frequency distribution method. The information might include student grades, local weather information, volleyball match point totals, etc. We must provide data in a relevant way for improved understanding after data gathering. Create a table that contains a summary of all the data's characteristics. The term "frequency distribution" refers to this.

Answer:31.5

Step-by-step explanation: Since we are decreasing 90 by 65%, we want to find 35% of 90. To do this, simply multiply 90 by 0.35 to get 31.5.

The length of the other side of the triangle is 30 cm. Thus, option b is correct.

The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC² = AB² + AC² in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

Here given that  hypotenuse = 32 and one side = 16

Using Pythagoras theorem

32² = 16² + x²

x = [tex]\sqrt{32^2 - 16^2}[/tex]

x = 30

Hence, the length of the other side of the triangle is 30 cm.

Particular Right Triangle Formula

The right triangle formula, which states that the square of a right-angled triangle's right triangle is equal to the product of its other two squares, is the fundamental Pythagoras theorem formula.

How long are the other two legs if a hypotenuse of a triangle with a 45°, 45°, and 90° angle is 32 units.

We are aware that Leg: Ankle: Length x = x: x: x2 is the formula for a triangle with a 45°, 45°, and 90° angle.

We can state that x2 = 32 because it is a known that the hypotenuse equals 32. As a result, x = 3 is determined.

After replacing this number of x = 3, the lengths of the empty sides may now be determined.

The solution to sin(t) is sin(t) = -√[1 -  cos²(t)]

From the question, we have the following parameters that can be used in our computation:

The angle t is the quadrant IV

This means that

sin²(t) + cos²(t) = 1

Subtract cos²(t) from both sides of the equation

So, we have the following representation

sin²(t) = 1 -  cos²(t)

Take the square root of both sides

sin(t) = ±√[1 -  cos²(t)]

sin(t) is negative in quadrant IV

So, we have

sin(t) = -√[1 -  cos²(t)]

Hence, the solution is sin(t) = -√[1 -  cos²(t)]

If the Heptagon  has been dissected into five triangle , the the proof that sum of the interior angle of any heptagon is always 900° is shown below .

To prove that the sum of the interior angles of a heptagon is 900°, we can use the five triangles that have been dissected from the Heptagon, as follows: let the 5 triangles be A , B , C , D and E .

we know that the sum of interior angle of triangle is always 180° ;

Triangle A: The sum of the angles of triangle A is 180°.

Triangle B: The sum of the angles of triangle B is 180°.

Triangle C: The sum of the angles of triangle C is 180°.

Triangle D: The sum of the angles of triangle D is 180°.

Triangle E: The sum of the angles of triangle E is 180°.

So , the sum of all the angles in the five triangles is 180°×5 = 900°, which is also equal to the sum of the interior angles of the heptagon.

A hypothesis is a) prediction of results and b) tentative statement that something maybe true.

A hypothesis is a statement or assumption made about a phenomenon or relationship, used as a starting point for further investigation. It is a tentative explanation for an observation, phenomenon or problem that can be tested through experimentation or additional data collection.

So a hypothesis can be true of false. A hypothesis is not certainly a fact too since it need to be tested.

If a hypothesis is proven to be true through experimentation and data analysis, it becomes a confirmed explanation or prediction. This means that the evidence supports the hypothesis and it can be used as a basis for further study or explanation. However, a true hypothesis is always subject to revision or rejection if new information or evidence becomes available.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

A pie is made in a circular shape.

Number of pieces in one pie = 8 pieces

Number of pieces of pie sold by first class of fifth grades = 4(2/8)

Number of pieces of pie sold by second class of fifth grades = 5(1/2)

The total number of pieces sold is = Pieces sold by first class + Pieces sold by second class

To find the pieces sold by first class multiply the fractional form by number of pieces -

4(2/8) × 8

34/8 × 8

The first class sold 34 pieces of pie.

To find the pieces sold by second class multiply the fractional form by number of pieces -

In mathematical terms, the null hypothesis states that the observed data follows the theoretical distribution, and is represented by

H0= The observed data follows the theoretical distribution. The alternative hypothesis, which is the opposite of the null hypothesis, states that the observed data does not follow the theoretical distribution, and is represented by
