Suppose that we have a ternaryrelationship R between entity sets A, B, and C such that (i) A has a key constraint; and (ii) Chas

a key constraintand total participation. These are the only constraints. A has attributes a1 and a2, with a1 being the key; B has attributes b1 and b2, with b1 being the key; and C has attributes c1and c2, with c1 being the key. R has no descriptive attributes. All of the above-mentioned attributes are to be stored as Strings of 10 characters. Write SQL statements that create tables corresponding to this information so as to capture as many of the constraints as possible. If you cannot capture some constraint, explain why.

Por qué no es tan común el uso de energías mas amigables con el medio ambiente en el país donde vives?
Effectus [21]

Answer:

Explanation:

English:

All forms of electricity generation have an environmental impact on our air, water, and land, but it varies. Of the total energy consumed in the United States, about 40% is used to generate electricity, making electricity use an important part of each person’s environmental footprint.

Producing and using electricity more efficiently reduces both the amount of fuel needed to generate electricity and the number of greenhouse gases and other air pollution emitted as a result. Electricity from renewable resources such as solar, geothermal, and wind generally does not contribute to climate change or local air pollution since no fuels are combusted.

The fuel mix for U.S. electricity generation

The chart below shows that most of the electricity in the United States is generated using fossil fuels such as coal and natural gas. A small but growing percentage is generated using renewable resources such as solar and wind.

Spanish:

Todas las formas de generación de electricidad tienen un impacto ambiental en nuestro aire, agua y tierra, pero varía. Del total de energía consumida en los Estados Unidos, alrededor del 40% se usa para generar electricidad, lo que hace que el uso de electricidad sea una parte importante de la huella ambiental de cada persona.

Producir y usar electricidad de manera más eficiente reduce tanto la cantidad de combustible necesario para generar electricidad como la cantidad de gases de efecto invernadero y otra contaminación del aire emitida como resultado. La electricidad de recursos renovables como la energía solar, geotérmica y eólica generalmente no contribuye al cambio climático ni a la contaminación del aire local, ya que no se queman combustibles.

Combustible para la generación de electricidad en EE. UU.

El cuadro a continuación muestra que la mayor parte de la electricidad en los Estados Unidos se genera utilizando combustibles fósiles como el carbón y el gas natural. Un porcentaje pequeño pero creciente se genera utilizando recursos renovables como la solar y la eólica.

Write a recursive function sumAll that accepts an integer argument and returns the sum of all the integers from 1 up to the numb
slavikrds [6]

Answer:

int sumAll(int n)//function definition.

{

   if(n==1)//if condition.

   return 1;

   else//else condition.

   {

       return n+sumAll(n-1);//return the value and call the function in recursive manner.

   }

}

Explanation:

  • The above-defined function is a recursive type function that is written in the c language, which holds the if and else condition.
  • When the user passes the largest value from 1, then the else condition will be executed which adds the largest value and pass the value after the decrement of the value as an argument.
  • When the value will become 1, then the function if-block will be executed which returns the value and ends the calling function recursively.

When pasting a circle drawn by the presentation software drawing tool into a spreadsheet, that circle will go into the selected
puteri [66]

False.

When you copy an object/image or insert it manually into an Excel spreadsheet cell, what will happen is that the object will lie on a separate layer and it will float on the sheet independently from the cell. If you want it embedded inside the cell, you can either resize both the picture and adjust the cell or merge the cells.
