No, these measurements do not form a triangle. The sum of any two sides of a triangle must be greater than the third side. In this case, 7 cm + 8 cm = 15 cm, which is not greater than the third side, 9 cm.

A triangle is a three-sided polygon, and all three sides must meet certain criteria in order to form a triangle. Specifically, the sum of any two sides must be greater than the third side. In this case, the given measurements are 7 cm, 8 cm, and 9 cm. When adding the 7 cm and 8 cm together, the sum is 15 cm, which is not greater than the third side, 9 cm. Therefore, these measurements do not form a triangle. To determine if a triangle can be formed with any given measurements, one must sum any two sides and ensure that the sum is greater than the third side. If the sum is not greater than the third side, then the measurements do not form a triangle.

What is the ordered pair?

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), with two values, expressed between parenthesis in a predetermined order. It aids visual comprehension by locating a point on the Cartesian plane. An ordered pair's numeric values can be integers or fractions.

Given ordered pairs are (5,10), (11,15), and (18,20).

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides. A quadrilateral of the shape of a rectangle has four 90-degree vertices and equal parallel sides. As a result, it is sometimes referred to as an equirectangular rectangle. Because its opposite sides are equal and parallel, a rectangle is also known as a parallelogram.

The graph of the reflected function: g(x) = 3^(-x) can be seen in the image at the end.

First, for any function y = f(x), a reflection across the y-axis is written as:

g(x) = f(-x)

So we only change the sign of the argument of the function.

The graphed function is the parent function:

f(x) = 3^x

Factor theorem is most commonly used for factoring a polynomial or integer and searching the roots of the polynomial. It is a particular case of a polynomial remainder theorem.

As defined in the introduction, a polynomial f(x) has a factor (x-a), if and only if, f(a) = 0. It is one of the processes to do the factorization of a polynomial.

Here we can prove the factor theorem, according to which we can.

factories the polynomial.

Consider a polynomial f(x) which is divided by (x-b), then f(c)=0.

Using remainder theorem,

f(x)= (x-b) q(x)+f(b)

Where f(x) is the target polynomial and q(x) are the quotient polynomial.

because f(b) = 0, So,

f(x)= (x-b) q(x)+f(b)

f(x) = (x-b) q(x)+0

f(x) = (x-b) q(x)

To solve and make the problem less intimidating, it is easier to just imagine that the < is a = sign. The only difference when solving a inequality versus an equation is that you flip the inequality sign when multiplying or dividing by a negative, which we won't need to worry about in this problem. Now, hopefully, this will make more sense when we are solving.

The first step is to add 20 to both sides:

15x - 20 < 40 (Add 20 to both sides)

15x < 60

Now, divide both sides by 15, so we are juts left with x:

15x < 60 (Divide both sides by 15)

x < 4

So, the inequality is true for any x value that is less than 4, or x<4.

At 2.5 seconds the ball reach its maximum height.

And, Its maximum height will be 25 feet.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation that describes the height (h) of a ball that is thrown straight up as a function of the (t) that the ball has been in the air is,

⇒ h = 40t - 16t²

So, For the time does the ball reach its maximum height, we can put h = 0, so we get;

⇒ h = 40t - 16t²

⇒ 40t - 16t² = 0

⇒ 16t² - 40t = 0

⇒ t (16t - 40) = 0

⇒ 16t - 40 = 0

⇒ 16t = 40

⇒ t = 40/16

⇒ t = 2.5 seconds

Now, The height function is a quadratic function which has the zeroes at  t = 0 and t = 2.5.

So, It has the maximum at x = midpoint between the roots 0 and 2.5, i.e. 1.25 seconds.

Hence, Substitute this value t = 1.25 seconds into the given height function, we get;

⇒ h = 40t - 16t²

⇒ h = 40 × 1.25 - 16 (1.25)²

⇒ h = 50 - 25

⇒ h = 25 feet

The solution to the trigonometric equation is x = ( 3π/4 ) , x = ( 7π/4 )

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin (-θ) = -sin (θ)

csc (-θ) = -csc (θ)

cos (-θ) = cos (θ)

sec (-θ) = sec (θ)

tan (-θ) = -tan (θ)

cot (-θ) = -cot (θ)

In the first quadrant, sin, cos and tan are all positive.

In the second quadrant going anti-clockwise, only sin is positive.

In the third quadrant going anti-clockwise, only tan is positive.

In the fourth quadrant going anti-clockwise, only cos is positive

Given data ,

Let the trigonometric equation be represented as A

Now , the value of A is

cot ( x - π/2 ) = 1   be equation (1)

On simplifying the equation , we get

cot ( - ( π/2 - x ) ) = 1

Now , cot (-θ) = -cot (θ)

So , - cot ( π/2 - x ) = 1

And , the value of cot ( π/2 - θ ) = tan θ

Substituting the values in the equation , we get

-tan x = 1 over the interval [ 0 , 2π ]

The value of x for -tan x = 1 is given by x = ( 3π/4 ) + nπ

when n = 1

x = ( 7π/4 )

So , the values of x are ( 3π/4 ) and ( 7π/4 )

We need to find out the relationship between a number and the previous number.

We can tell that there is no common difference since 78125 - 390625 cannot possibly equal 3125 - 15625.

We can try to check if this is a geometric sequence.

78125/390625 = 0.2

15626/78125 = 0.2

3125/15625 = 0.2

Each number is 1/5 of the previous number.

3125/5 = 625

625/5 = 125

125/5 = 25

The requried dimension of the original rectangle is given as length = 25 cm, width = 10 cm.

The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.

Let the length and width of the original rectangle be x and y,
According to the quesiton,

The perimeter of a rectangle is 70 cm.
2 [x + y] = 70
x  + y = 35 - - - -(1)

Now,
its length is decreased by 5 cm and its width is increased by 5 cm, its area will increase by 50 cm².
Area of the new rectangle = area of the original rectangle + 50
(x  - 5)(y + 5) = xy + 50

from equation 1,

(x - 5)(35 - x + 5) = x(35 - x) + 50
-x² - 200 + 40x + 5x = 35x - x² + 50
45x - 35x = 50 + 200
10x = 250
x = 25

Now,
y = 35 - 25
y = 10

Thus, the requried dimension of the original rectangle is given as length = 25 cm, width = 10 cm.

(a) We know that 30% of the members of the club are female and 20% of these females own cars, and 30 female members own cars.

We can use this information to calculate the total number of female members in the club.

If 30% of the members are female and 20% of these females own cars,

then 20/100*30 female members = 6% of the total members own cars.

This means that 6% of the total members are female members who own cars.

Therefore, 30 female members / 6% = 500 female members.

So there are 500 female members in the club.

(b) If 30% of the members are female, then the total number of members is (100/30)*500 female members = 1666.67 members

(c) To increase the percentage of female members to 37.5%, we need to calculate the number of additional female members required to reach this goal. The current percentage of female members is 30% and we want to increase it to 37.5%. Therefore, we need an additional 37.5-30 = 7.5%. If the current number of female members is 500, to increase the percentage by 7.5%, we need an additional of 7.5/100*1666.67 = 125 additional female members.

In Mathematics, a pie chart can be defined as a type of graph that is used for the graphical representation of the proportion relationship between each part or unit to a whole, especially by dividing a circle into various sectors or sections.

Assuming 200 students were surveyed at 14%, the number of students who would choose art as their favorite subject can be calculated as follows;

Number of students for arts = 0.14 × 200

Assuming 400 students were surveyed at 16%, the number of students who would choose social studies as their favorite subject can be calculated as follows;
