A square name tag has sides that are 10 centimeters long. What is the name tag's area?

The distance that tire covered in 8 rotations with diameter 25 inches is 628in using circle circumference's formula .

What is circumference of circle ?

The circumference of a circle is defined as the linear distance around it. In other words, if a circle is opened to form a straight line, then the length of that line will be the circle's circumference.

The formula is :

2πr where r is the radius of the circle.

We know that diameter = 2*radius.

Given diameter = 25 inches

So, the radius = 25/2 inches.

So, the circumference = 2*(22/7)*(25/2)

Circumference of circle = distance covered by tire in one rotation.

So, the distance covered in 8 rotations = 8 * circumference

                                                                  = 8* 2*(22/7)*(25/2)

                                                                  = 628.5 inches

                                                                  ≈ 628 in

To derive the formula that goes through these two points, we use the general equation for an exponential equation.

Y = a(b)^x

There we will substitute the two points into this equation to get two equations

45 = a(b)^2

5/9= a(b)^-1

By dividing the first equation by the second, we obtain:

27 = b^3

Therefore b= 3

We plug b=3 into the first equation using the second point:

45 = a(3)^2

We get a = 5

Therefore the equation is y = 5(9)^x

We can verify this equation by plugging in the two points given to see if it works.

5/9 = 5(9)^-1

5/9 = 5/9

And:

45 =5(9)^2

45 = 45

This means that for any vector v in the vector space V, there is a vector 0 in V such that v + 0 = v.

This is known as the identity property, and it states that adding 0 to any vector in V does not change the original vector. The identity property is an essential part of the definition of a vector space.

In general, a vector space is a set of objects called vectors that can be added together and multiplied ("scaled") by numbers, called scalars. Scalars are often taken to be real numbers, but there are also vector spaces with scalar multiplication by complex numbers, rational numbers, or generally any field.

After solving the equation, the value obtained for m ∠B will be equal to 132°.

An angle results from the intersection of two lines at a point. The term "angle" describes the width of the "gap" that exists between these two rays. It's represented by the symbol.

Angles are most frequently measured in degrees and radians, a measurement of roundness or rotation. Angles are a part of everyday existence.

As per the given information in the question,

The inside angle plus the external angle add up to 180°.

So,

m ∠B = (14x − 22)°

14x - 22° + 6x - 18° = 180°

14x + 6x - 22° - 18° = 180°

20x - 40° = 180°

20x = 180° + 40°

20x = 220°

x  = 220° / 20

x = 11°

Now, let's find m∠B.

m ∠B = (14x − 22)°

Put x = 11° in above equation,

m ∠B = (14(11) − 22)°

m ∠B = 154° - 22°

m ∠B = 132°.

The perimeter of triangle XYZ is calculated as: 48 units.

The perimeter of a triangle is found by summing all the lengths of the three sides of the triangle.

Given the following measures as shown in the image below as:

AC = 7

AB = 5

XY = 24

The perimeter of triangle XYZ = XY + YZ + XZ

Based on the triangle midsegment theorem, we have:

YZ = 2(AC) = 2(7)

YZ = 14

XZ = 2(AB) = 2(5)

XZ = 10

Therefore:

The perimeter of triangle XYZ = 24 + 14 + 10

Answer:

growth

1.8%

Step-by-step explanation:

If the number raised to the power x is between 0 and 1, it is decay since as the exponent increases, the value of the power expression decreases.

For example, think of 0.1, a number between 0 and 1.

0.1^x

x = 1, 0.1^1 = 0.1

x = 2, 0.1^2 = 0.01

x = 3, 0.1^3 = 0.001

As you see, as x increases, the value of the expression decreases from 0.1 to 0.01 to 0.001

Now look at a power in which the base is greater than 1.

If the number raised to the power x is greater than 1, it is growth since as the exponent increases, the value of the power expression increases.

For example, look at 1.5^x

1.5^x

x = 1, 1.5^1 = 1.5

x = 2, 1.5^2 = 2.25

x = 3, 1.5^3 = 3.375

As you see, as x increases, the value of the expression increases from 1.5 to 2.25 to 3.375.

Now our problem:

y = 9200(1.018)^x

What base is raised to x?

Answer: 1.018

Since 1.018 is greater than 1, as the exponent, x, increases, the value of 1.018^x increases. Therefore, this is exponential growth.

1.018 = 1 + 0.018 = 1 + 1.8%

It takes 5 years for the population to decrease to 46785 from the current population of 48500 of a small city whose population is decreasing by an average of 325 people per year.

It is given that,

Current population = 48500 people

Rate of decrease = 325 per year

Number of years = x

decreased population after x years  = 46785

Then, the equation is

46785 = 48500 - 325x

On simplifying the obtained equation, we get

46785 = 48500 - 325x

⇒ 325x = 48500 - 46785 = 1625

⇒ x = 1625/325 = 5 years

So, the people become 46785 after 5 years.

Answer:

the value of x is 10

Step-by-step explanation:

Since LMNO is a parallelogram, the opposite sides are parallel and have the same length. This means that NO and LM have the same length, which we can call y. We can write the following equations to represent the given information:

NM = x + 32

OL = 2x + 22

NO = y

LM = y

Since NO and LM have the same length, we can set their lengths equal to each other to find the value of y:

x + 32 = y

2x + 22 = y

We can solve this system of equations by setting the two equations equal to each other and solving for x:

x + 32 = 2x + 22

-x = -10

x = 10

Substituting the value of x back into the equations for NM and OL, we find that:

NM = 10 + 32 = 42

OL = 2(10) + 22 = 32

Therefore, the value of x is 10, and the lengths of NM and OL are 42 and 32.

Formula for how high the ball rebounds on the nth bounce is 80 (3/4)ⁿ  ft and the rebound on 5th bounce is 14.24 ft.    

It is given that the ball is dropped from 80 ft and it rebounds (3/4)th of the height it has fallen.

Firstly , using logic ,

The height reached by the ball on its 1st rebound = 80(3/4) = 60 ft

Similarly , calculating on it's 2nd rebound = 60(3/4) = 45 ft

and on 3rd rebound = 45(3/4) ft.

This forms a sequence , known as GP (Geometric Progression).

A Geometric Progression in mathematics, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Hence , here the first term : a = 60 ft

and common ratio is : r = 3/4

the general term for rebound on nth bounce

= 60 * (3/4)ⁿ⁻¹  = 80 (3/4)ⁿ  ft

In order for mn to be even, m must be even or n must be an even number.

The relationship between two propositions when the subject and predicate of one are respectively the negation of the predicate and the negation of the subject of the other.

Suppose that the statement “m is even or n is even” is not true. Then both m and n are supposed to be odd. Let’s see if the product of two odd numbers is an even or an odd number:

Let n and m be equal to 2a +1  and 2b + 1 respectively, then their product is:

                 (2a +1) (2b + 1) = 4ab + 2a + 2b + 1

This shows that the expression 2(2ab +a + b) + 1  is of the form 2n +1,  thus the product is odd. If the product of odd numbers is odd, then mn is not true to be even. Therefore, in order for mn to be even, m must be even or n must be an even number.

The Kinetic Energy of an object depends on the object's and velocity , and can be written as v = m

Kinetic Energy of an object with a mass = 1,700 kilograms

Traveling = 50 meters per second

Radius = 4.92 ft

Kinetic energy, which may be seen in the movement of an item or subatomic particle, is the energy of motion. Kinetic energy is present in every particle and moving object. Examples of kinetic energy in action include a person walking, a baseball soaring through the air, a piece of food falling from a table, and a charged particle in an electric field.

Kinetic Energy of a body is given by ,

1/2 mv²

Where m = mass = 1700 kg

v = velocity = 50m/s

Therefore ,

KE = 1/2 * 1700kg * 50m/s

KE = 2125000 J.

Now to calculate the volume

Let's assume that the solution to the problem will be found using your formula. If so, let's carry out the following operations when solving for v in the equation:

On multiplying the equation by 2, the outcome is

2[tex]r^{2}[/tex]

=3[tex]\sqrt{3V}[/tex]

To find volume

enter (v=(2[tex]r^{2}[/tex])/33)

rationalize the right side of the equation's numerator.

v=(2π[tex]r^{2}[/tex] )

A simplified version of 3/333 is

v=(2[tex]r^{2}[/tex])3/9.

Substitute

v=(23.143.1523)/9

v=11.9.

Therefore,
