List three functions that you can perform with a database that you cannot perform with a spreadsheet.

1 answer:

5 0

There are some function which can be performed with database but not with a spread sheet, these functions include:
1. Enforcement of data type.
2. Support for self documentation.
3. Defining the relationship among constraints in order to ensure consistency of data.

Which of the following reflects Moore's law? Multiple Choice The doubling of computer chip performance per dollar every two year

Katena32 [7]

Answer:

The correct answer is A.

Explanation:

Moore's Law states/predicts that the maximum number of transistors that can be used on integrated circuits (processors etc.) will be doubled every two years so it basically predicts an exponential growth in terms of transistors used.

Doubling the number of transistors used means that it will almost certainly increase the performance of the processors. Of course there are a lot of other variables that the performance depends on but Moore's Law is proven to be true and is being used since 1960's. The answer given in option A is the one that best reflects on this law.

I hope this answer helps.

Assume that a function named swapdoubles has been defined and is available for use in this exercise: that function receives two

Nata [24]

Answer:

C++ Code:

void sort3(double &a, double &b, double &c)

{

if(a > b)

swapdoubles(a,b);

if (b > c)

swapdoubles(b,c);

if (a > b)

swapdoubles(a,b);

}

Explanation:

To change the values of a,b,c within the function, we pass the values by reference. Let us assume that number a = 3.14, b = 2.71, c = 3.04. Since a > b, values of a and b will be swapped.Now a = 2.71 and b = 3.14. Similariy, since b > c, they will be swapped. This way, we move the largest number to its correct position in the first two steps. If there are only three numbers, and the largest number is in its correct position, then for the two remaining numbers, we will only need atmost one swap to exchange their positions. hence, we perform a comparison of a > b once again to see if the b is smaller than a. if its not, then all a,b,c are in sorted order.

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use

jeyben [28]

Question:

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin.

Answer:

This solution is implemented in C++

double compute_gas_volume(double P, double T, double n){

double V = 8.3144621 * n * T/P;

return V;

}

Explanation:

This line defines the function, along with three parameters

double compute_gas_volume(double P, double T, double n){

This calculates the volume

double V = 8.3144621 * n * T/P;

This returns the calculated volume

return V;

}

To call the function from the main, use:

cout<<compute_gas_volume(P,T,n);

Where P, T and n are double variables and they must have been initialized
