The  \(1.2742*10^4 km / L\) times longer is the diameter of earth than the piece of wood's length.

The radius of earth is 6371 km.

Let's say the length of the piece of wood is L.

The diameter of the Earth is 2 times its radius

The radius of our planet, The Earth, is the distance from the center of the Earth to a point on or near its surface, and it ranges from nearly 6,378 km to nearly 6,357 km.

The diameter of a circle is the length of the line starting from one point on a circle to another point and passing through the center of the circle. It is equal to twice the radius of the circle. It is usually denoted by ‘d’ or ‘D’.

The diameter of the Earth is 2 times its radius, or 2 x 6371 km = 12742 km.

The diameter of the Earth is 12742 km / L times longer than the length of the piece of wood.

In scientific notation, we can express this as:

12742 km / L = \(1.2742*10^4 km / L\)

The  \(1.2742*10^4 km / L\) times longer is the diameter of earth than the piece of wood's length.

Answer:

Step-by-step explanation:

Function of the Annual Profit of the company, say P is P(t) = ( 1.1 )t² + 12.2 t + 87 where t is represent time in years.

Function : is an expression which represents the relationship between two variable where one is dependent and other one is independent.

Annual Cost is the total amount of expenses a company (organisation) spends on an employee during one year.

we have given, Cost C ( in thousand of dollar)

and revenue R (in thousand of dollar) for a company. Cost function C, is C = 254 - 9t + (1.1)t² where t time in year .

and Revenue function R = 341 - 3.2t

the value t = 9 represents 9 years. If P represent the Annual profit then

P = R - C i.e., P = 341 - (3.2)t - 254 - 9t + (1.1)t²

= (1.1)t² - (12.2)t + 87

Hence, the annual profit (in thousand dollars) is

P = (1.1)t² - (12.2)t +87 .

Answer

x = 28

y = 32

Step-by-step explanation:

Non-vertical angles (top and bottom) are congruent

Thus

5x - 15 = 4x + 13

x = 28

and so each non-vertical is

5(28) -15 = 125

4(28) + 13 = 125

Diagonals bisect vertex angles (left and right) Thus we have one vertical angle as (y + y) = 2y

and another vertical angle as (y -9) + (y - 9) = 2y - 18

All the angles in a kite adds up to 360

So

125 + 125 + 2y + (2y - 18) = 360

250 + 4y - 18 = 360

4y = 128

y = 32

Answer:

it would be negative (-8)

Step-by-step explanation:

-5.8 + -2.2 = -5.8 - 2.2

this would result in a negative number (-8)

the correct answer is A. $63,200.

To compute the cost component of the machine, we need to add up all the related expenditures to the cash price of the machine.

Cash price of the machine: $60,000

Sales taxes: $2,000

Insurance after installation: $200

Installation and testing: $1,000

Total related expenditures: $2,000 + $200 + $1,000 = $3,200

Cost component of the machine: Cash price + Total related expenditures

Cost component of the machine = $60,000 + $3,200 = $63,200

Therefore, the correct answer is a. $63,200.

The fraction which is greater is 3/10. That means there are more flute players than trumpet players in the band.

Perhaps what you meant was "Which is the greater fraction of the bands: flute players or trumpet players?"

First of all, we need to make the denominators of fraction 3/10 and 1/12 the same so we can actually compare the given fractions. To do this, we can take the least common multiple (LCM) of the denominators and multiply the numerator and denominator of each fraction by certain numbers so that the denominators equal to the LCM.

The multiples of 12 are 12, 24, 36, 48, 60 etc. The multiples of 10 are 10, 20, 30, 40, 50, 60 etc. Notice that the first common multiple is 60. That's the LCM of 12 and 10.

3/10 is equal to 18/60 while 1/12 is equal to 5/60. 18 is greater than 5 so the first fraction is greater, which means there are more flute players than there are trumpet players in the band.

Answer:

e = 5.25 , f = 4.5

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion , that is

\(\frac{DF}{AC}\) = \(\frac{EF}{BC}\) ( substitute values )

\(\frac{e}{7}\) = \(\frac{3}{4}\) ( cross- multiply )

4e = 7 × 3 = 21 ( divide both sides by 4 )

e = 5.25

and

\(\frac{DE}{AB}\) = \(\frac{EF}{BC}\) , that is

\(\frac{f}{6}\) = \(\frac{3}{4}\) ( cross- multiply )

4f = 6 × 3 = 18 ( divide both sides by 4 )

f = 4.5

Answer:

I'll give you some clues in the solution. Please read them so you can do the rest faster.

Solution:

First thing you do is write the vertex. The vertex is basically the last number in the absolute value bars and the number outside of them (to the right of the bars). The vertex is the opposite of the last number in the absolute value brackets and if there is no number to the right, assume it is 0.

We start at (2,0).

The domain is 99% of the time all real numbers. Write that for domain.

The range is the y value where things start to increase (the y value of the vertex). The range is 0.

The type of function is absolute value function btw

The linear function is popular in economics. It is attractive because it is simple and easy to handle mathematically. It has many important applications.

Linear functions are those whose graph is a straight line.

A linear function has the following form:-

y = f(x) = a + bx

A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

a is the constant term or the y-intercept. It is the value of the dependent variable when x = 0.

b is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of the dependent variable.

We need to find whether the two given triangles are congruent.

The given triangles are congruent.

The distance between two points is given by

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

A(2,-8) and B(-5,-2)

\(AB=\sqrt{(-5-2)^2+(-2-(-8))^2}\\\Rightarrow AB=\sqrt{49+36}\\\Rightarrow AB=\sqrt{85}\)

D(-9,7) and E(-11,12)

\(DE=\sqrt{(-11-(-9))^2+(12-7)^2}\\\Rightarrow DE=\sqrt{29}\)

B(-5,-2) and C(-7,3)

\(BC=\sqrt{(-7-(-5))^2+(3-(-2))^2}\\\Rightarrow BC=\sqrt{29}\)

E(-11,12) and F(-2,1)

\(EF=\sqrt{(-2-(-11))^2+(1-12)^2}\\\Rightarrow EF=\sqrt{202}\)

A(2,-8) and C(-7,3)

\(AC=\sqrt{(-7-2)^2+(3-(-8))^2}\\\Rightarrow AC=\sqrt{202}\)

D(-9,7) and F(-2,1)

\(DF=\sqrt{(-2-(-9))^2+(1-7)^2}\\\Rightarrow DF=\sqrt{85}\)

It can be seen that \(AB=DF=\sqrt{85}\), \(BC=DE=\sqrt{29}\) and \(AC=EF=\sqrt{202}\).

Since, each side of triangle ABC is equal to one side of triangle DEF they are congruent to each other.

Answer:

He will have 13 packages containing 3 pairs of headphones and 1 music player each.

Step-by-step explanation:

He has 39 pairs of headphones and 13 music players.

He wants to sell both set of items in identical packages.

To do this he has to divide them in such a way that the same number of both set of objects are in every box.

Let us find the ratio of the pairs of headphones to music players:

39 : 13 = 3 : 1

Therefore, dividing the pairs of headphones into 3 parts and the music players into 1 part, he can have identical packages.

So, he will have 13 packages containing 3 pairs of headphones and 1 music player each.

The velocity of a particle = i + 2t j

The acceleration of a particle = 2 j

The speed of a particle = \(\sqrt{1 + 4t^{2} }\)

Here,

The position function is, \(r (t ) = ti + t^{2} j +2k\)

We have to find, the velocity, acceleration, and speed of a particle with the given position function.

What is Velocity of a particle with the given position function?

The instantaneous velocity v(t) of a particle is the derivative of the position with respect to time. That is, v(t)=dx/dt.

Now,

The position function is, \(r (t ) = ti + t^{2} j +2k\)

The velocity of a particle = \(\frac{d r(t)}{dt}\)

\(r (t ) = ti + t^{2} j +2k\)

\(\frac{d r(t)}{dt} = i + 2t j\)

The acceleration of a particle = \(\frac{d^{2} r(t)}{dt^{2} }\)

\(r (t ) = ti + t^{2} j +2k\)

\(\frac{d r(t)}{dt} = i + 2t j\)

\(\frac{d^{2} r(t)}{dt^{2} }= 2j\)

The speed of a particle = \(| \frac{d r(t)}{dt}| = |v(t)|\)

\(\frac{d r(t)}{dt} = i + 2t j\)

\(|v(t)|=\sqrt{1 + 4t^{2} }\)

Hence, The velocity of a particle = \(i + 2t j\)

The acceleration of a particle = \(2 j\)

The speed of a particle = \(\sqrt{1 + 4t^{2} }\)
