“That you want us to call him Nikhil.” “That is correct.” Mrs. Lapidus nods. “The reason being?” “That is our wish.” “I’m not sure I follow you, Mr. Ganguli. Do you mean that Nikhil is a middle name? Or a nickname? Many of the children go by nicknames here. On this form there is a space—” “No, no, it’s not a middle name,” Ashoke says. He is beginning to lose patience. “He has no middle name. No nickname. The boy’s good name, his school name, is Nikhil.” Mrs. Lapidus presses her lips together and smiles. “But clearly he doesn’t respond.” “Please, Mrs. Lapidus,” Ashoke says. “It is very common for a child to be confused at first. Please give it some time. I assure you he will grow accustomed.” Which statement best explains how Lahiri explores conflict brought on by globalization? 1.Lahiri uses descriptions to compare elements of traditional schooling in different cultures. 2.Lahiri uses the characters’ actions to show how people from different cultures can work together to resolve conflicting values. 3.Lahiri uses the setting to highlight her opinions on the educational systems in both the United States and India. 4.Lahiri uses dialogue to show how people from different cultures can have difficulty relating to each other’s experiences.

The answer is D. Lahiri want’s to bring attention to how much cultural tension there is between an Indian transfer student and a typical American school. In this  example the conflict isn’t between the child and the teacher: but the communication barrier they have over his name.

Choose the values that are in the range….

now… that fraction, becomes undefined if the denominator becomes 0

when does that happen?  well, it happens when sin(y) becomes 0, when is that?, notice your Unit Circle, that happens at 0, π, 2π, 3π and so on

now, on those angles, sin(y) is 0, and the rational of the cotangent, becomes undefined, so, therefore, those angles are NOT valid values for the angle, and outside the range.

now, just check for those, everyone else should be in the range.

From the table below, determine whether the data shows an exponential function. Explain why or why not. (x) -5, -4, -3, -2 (y) 0.5, 2, 8, 32 A) Yes; the domain values are at regular intervals and the range values have a common factor 8. B) Yes; the domain values are at regular intervals and the range values have a common factor 4. C) No; the domain values are not at regular intervals. D) No; the domain values are at regular intervals and the range values have a common factor 4. Please help, and please give me an explanation on the answer you choose because I need to make corrections. Please.

Option B-  Yes; the domain values are at regular intervals and the range values have a common factor 4.

Step-by-step explanation:

Given : The data

(x) -5,   -4,  -3,   -2

(y) 0.5,  2,   8,   32

To find : The data shows an exponential function or not

Solution :

The general form of an exponential form is

To check whether the data give the exponential function we form equation with the help of two points and verify the other two points .

Let x= -5 and y=0.5

……[1]

Let x= -4 and y=2

………[2]

Equate LHS because RHS is equal in equation [1] and [2]

Put back in [2]

.

a=512 and b=4

Exponential function –

To verify this function put

1) x=-3

The point satisfied.

2) x=-2

The point satisfied.

Therefore, The given data is an exponential function

The domain values are at regular intervals and the range values have a common factor 4 because b=4 and the change happen but value of b remain same.

Hence, Option B is correct.

Yes; the domain values are at regular intervals and the range values have a common factor 4.

If Denise wanted to create a function that modeled an exponential function with base of 12 and what exponents were needed to reach specific values, how would she set up her function? f(x) = x12 f(x) = log12x f(x) = 12x f(x) = logx12

Denise creates the exponential function

assume she want to find for what value of x, her function reaches the value, 3, or 8.2, or any value a (larger than 0)

so she shants to solve    (“for what value of x, is 12 to the power of x equal to a?”)

this expression is equivalent to

(so 12 to the power of x is a, for x=)

we can generalize this result by creating a function f.

In this function we enter x, the specific value we want to reach. f will calculate the exponent needed, in the following way:

(example: we want to calculate at which value is equal to 5?

check:, which is true, by properties of logarithms)

Does the US values get exported to the peripheral nations?

Immanuel Wallerstein explained this relationship as developed World Systems Theory. The system consists of three levels. First is the main core country which dominates and has control of the other two levels. The second is semi periphery, which is both a core and peripheral (dependent on capital and products to the core). The last is a dependent country to the core, peripheral.

The US is a core country that has assets in terms of capital and product that it extends to peripheral nations. In a way, it gains control over peripheral because of its economic dominance. This makes the US have an edge to the raw materials and skilled labor of the peripherals

Given (x-1)2=50, select the values of x X=-49 X=51 X=1+5sqr root 2 X=1-5sqe root 2

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.

False

Step-by-step explanation:

Suposse that we are given a function f(x) and a constant value h.

1. Case:

If we take the function g(x)=f(x)+h, then the graph of the function g(x) will be the graph of the funcion f(x) moved up or down.

2.Case:

If we take the function g(x)=hf(x), then the graph of the function g(x) will be the graph of the function f(x) just taller or shorter.

3.Case:

If we take the function g(x)=f(x-h), then the graph of the function g(x) will be the graph of the fuction f(x) moved horizontally.

4. Case:

If we take the function g(x)=f(hx), then the graph of the function g(x) will be tha graph of the function f(x) wither or thiner.

For example:

If we take f(x)=sin(x) and h=2. Then, if we take g(x)=sin(2x) then f(0)=g(0)=0, which means that the graph of the functiction is not moved up or down. However, f(π/2)=sin(π/2)=1 and g(π/2)=sin(π)=0 which gives us a hint that the graph of the function became thiner.

Which of the following is an important step in the process of conflict resolution? A. defining the problem and proposing a solution B. requiring all participants to adopt your viewpoint C. agreeing only with your own values D. none of the above (Whoever answers it first gets brainliest!!!! Plzzzzz help!!!!)

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

Explanation:

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t²      (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the  equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

25) Answer is: less metallic and more nonmetallic.

Electronegativity increases from left to right across a period, atoms have tendency to attract electrons.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

Radioisotope has an unstable atomic nucleus and emit energy and particles when it changes to a more stable form.

Francium (Fr) is element with atomic number 87 (87 protons and 87 electrons).

Boiling is the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

The Celsius scale was based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atm pressure.

There are two types of reaction:

1) endothermic reaction (chemical reaction that absorbs more energy than it releases, ΔH>0).

2) exothermic reaction (chemical reaction that releases more energy than it absorbs).

For example, the breakdown of ozone is an endothermic process. Ozone has lower energy than molecular oxygen (O₂) and oxygen atom, so ozone need energy to break bond between oxygen atoms.

The average kinetic energy of molecules depends on the temperature.

As temperature increases, molecules gain more energy from surrounding and move faster.

Kinetic energy (standard unit is the joule J) depends on speed of the molecule.

Solid gains kinetic energy to become a liquid and then becomes a gas.

This was famous Rutherford’s Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles.

Rutherford observed the deflection of alpha particles on the photographic film.

Alpha particles are helium atom particles, consist of two protons and two neutrons.

According to Rutherford model of the atom: atoms have their charge concentrated in a very small nucleus.

For example, calcium oxide.

Calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻).

Because it has strong ionic bonds, it has high melting point (around 2600°C).

Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

32) Answer is: a scientific model.

A scientific model is a representation of an idea, an object, a process or a system that is used to describe and explain phenomena that cannot be experienced directly.

33) Answer is: the superscript is mass number and the subscript is atomic number.

Atomic number(Z) is the number of protons, which is characteristic of a chemical element..

Mass number (A) is the total number of protons and neutrons in a nucleus.

Which values of x and y would make the following expression represent a real number? (6 + 3i)(x + yi)

5 in 0.05 is 10 times greater than 5 in 0.005.

Step-by-step explanation:

To find : In which number does the digit 5 have greater value 0.05 or 0.005 how many times as great is it and how do you know ?

Solution :

According to the place value stem,

Ones      Tenths      Hundredths     Thousandths

0              0                   5                                           – 0.05

0              0                   0                        5                 – 0.005

In 0.05 5 is in hundredths place and in 0.005 5 is in thousandths place.

So, 5 in 0.05 is 10 times greater than 5 in 0.005.

According to max weber, the values of self-denial and self-discipline that provided the ethic necessary for capitalism to flourish are encapsulated in the ________ ethic.

Americans will pay more for goods produced in Mexico in 2011.

Explanation:

This is a situation of devaluation of the dollar in relation to the Mexican peso. If in 2009 the dollar was worth 16 pesos, but in 2011 it is 14, it means that the purchasing power of the dollar in relation to the Mexican peso has decreased, although it is still high.

In that case, for an American to buy products produced in Mexico in 2011, he or she will spend a little more dollars than he or she would spend in 2009. This is common, since the currencies fluctuate according to the financial market . Thus, the dollar can be valued or devalued, as happened in this example.

If, for example, in 2015 the dollar will buy 20 pesos, it will mean that the dollar appreciated in relation to the peso, increasing the purchasing power of Americans for Mexican products.
