Answer:
// here is code in C++(bmi.cpp).
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
float weight,height;
cout<<"enter the weight(in kilograms):";
//read the weight
cin>>weight;
cout<<"enter the height(in meters):";
//read the height
cin>>height;
// calculate the bmi
float bmi=weight/(pow(height,2));
// print the body-mass index with two decimal places
cout<<"BMI is: "<<fixed<<setprecision(2)<<bmi<<endl;
return 0;
}
Explanation:
Read the weight from user and assign it to variable "weight",read height and assign it to variable "height".Then find the body-mass index as (weight/height^2).Here weight should be in kilograms and height should be in meters.
Output:
enter the weight(in kilograms):75
enter the height(in meters):1.8
BMI is: 23.15
Answer:
Wireless technology.
Explanation:
In earlier years, the broadcasting of information or any video or audio type was done "over-the-air". This means that sharing or the distribution of any content was done "wireless", through the use of transmitters that are wireless or requires no physical connecting wires.
Wireless technological form of broadcasting became the original form of distributing media, be it entertainment, news or information, etc. This 'over-the-air' broadcasting was then replaced by the cabled-wires transmission later on.
Answer:
a) 6
b) 11
c) 11
Explanation:
Given
Prime value q =n= 19
primitive root (a) =10
Alice secret key = 4
Bob secret key = 6
a) The value Alice Sends to Bob
aPrivate key of Alice mod n
= 10^4 mod 19
= 10000 mod 19
=6
b)The value Bob sends to Alice
aPrivate key of Bob mod n
= a3 mod n
= 10^6 mod 19
=1000000 mod 19
= 11
c)
Both the parties calculate the value of secret key at their respective side.
secret key obtained by Alice
= 11
secret key obtained by Bob
= 11
Finally, both the parties obtain the same value of secret key.
The value of common secret key = 17
Answer:
SATA Cable
Explanation:
SATA (Serial Advanced Technology Attachment) Cable is a connection made between Computer hard drives and the motherboard. When a computer gives an error on startup that OS not found, there's a possibility that the drive containing the OS is not well connected to the motherboard. Making sure it is well connected to the motherboard will possibly fix the issue.
