Explanation:
Answer: 83.17
Explanation:
By definition, the dB is an adimensional unit, used to simplify calculations when numbers are either too big or too small, specially in telecommunications.
It applies specifically to power, and it is defined as follows:
P (dB) = 10 log₁₀ P₁ / P₂
Usually P₂ is a reference, for instance, if P₂ = 1 mW, dB is called as dBm (dB referred to 1 mW), but it is always adimensional.
In our question, we know that we have a numerical ratio, that is expressed in dB as 19.2 dB.
Applying the dB definition, we can write the following:
10 log₁₀ X = 19.2 ⇒ log₁₀ X = 19.2 / 10 = 1.92
Solving the logarithmic equation, we can compute X as follows:
X = 10^1.92 = 83.17
X = 83.17
Answer:
B. Replace the Bluetooth headset with a new pair.
Explanation:
Since all other mobile devices, after receiving the "corporate-wide" OS update, aren't having issues with pairing with Bluetooth headsets, we can safely conclude that the OS update isn't the issue.
To find out if the Bluetooth headset is not the culprit, we can try to pair the mobile device with a different headset. If it pairs correctly, then we can conclude that the old Bluetooth headset might have a fault, or it might need to be disconnected/forget from the device and paired gain.
Explanation:
Pretty sure its a group of two or more computers that are linked thogether
Answer:
//here is code in c++.
#include <bits/stdc++.h>
using namespace std;
int main()
{
// variable
int temp;
cout<<"Please enter the temperature:";
//read temperature from user
cin>>temp;
int n;
// reduce the case for switch
n=temp/10;
// print output according to the switch case
switch (n) {
case 7:
case 6:
cout<<"tennis"<<endl;
break;
case 5:
case 4:
cout<<"golf"<<endl;
break;
default:
if(temp>=80)
cout<<"swimming"<<endl;
else
cout<<"skiing"<<endl;
break;
}
return 0;
}
Explanation:
Read the value of temperature from user and assign it to variable "temp".
Calculate n=temp/10, to limit the number of cases in the switch statement.
if temperature is greater or equal 60 & less than 80, it will print "tennis".
If temperature is greater or equal 40 & less than 60, it will print "golf".
in default case, if temperature is greater than 80, it will print "swimming".
if less than 40, print "skiing".
Output:
Please enter the temperature::67
tennis
