The power ratio 1.774 is equivalent to how many dB?

kvv77 [185]

Answer:

2.489 dB

Solution:

As per the question:

Power ratio, $\frac{P'}{P} = 1.774$

The Equivalent of this power ratio in decibel or dB is calculated by taking the log of the power ratio as below:

$\frac{P'}{P}_{dB} = 10log_{10}\frac{P'}{P}$

$\frac{P'}{P}_{dB} = 10log_{10}\times 1.774 = 10\times 0.2489 = 2.489 dB$

Thus the value of the power ration in decibel comes out to be 2.489 dB

gavmur [86]

Complete Question:

Write statements that output variable numComputers as follows. End with a newline. There are 10 computers.

#include <iostream>

using namespace std;

int main()

{

int numComputers;

cin >> numComputers; // Program will be tested with values: 10.

...

return 0;

}

Answer:

cout << "There are ";

cout << numComputers;

cout << " computers." << "\n";

Explanation:

Using three cout statements the string "There are 10 computers." is printed out, notice that the variable numComputers is entered by the user when the program is run. Another way of concatenating an integer variable and string for printout is by the use of the + (plus) operator.

A=np.array([[4,3,2],[5,6,3],[3,5,2]]);

B=np.array([[3,-1,2,6],[7,4,1,5],[5,2,4,1]]);

X=np.dot(np.linalg.inv(A),B);

print("X=");

print(X);
