The function that takes three decimal numbers as inputs and finds the sum of those inputs and returns the sum has been given below
What is programming?
Program is the set of instructions given to the computer so that the computer can execute those instructions. The act of writing program is called programming.
The program has been shown below
#include<stdio.h>
using namespace std;
int main()
{
double n1, n2, n3;
double s;
printf("Enter first numbers");
scanf(%lf, &n1);
printf("Enter second numbers");
scanf(%lf, &n2);
printf("Enter third numbers");
scanf(%lf, &n3);
s = n1 + n2 + n3;
printf("Sum = %f", s);
return 0;
}

Answer:

Step-by-step explanation:
As per the given question
As we know that
f(x) and x are related by following equation

where
b is the common ratio
Now first we have to compute the value for b which are as follows


Like if we take the ratio by this method than it comes 1.25
Therefore the common ratio, b = 1.25
So,
a = 5,120
Hence, the equation which model the relationship between the number of weeks and the number of viewers is

Answer:
4.59*
Step-by-step explanation:
We need to move the decimal so there is only one zero to the left of the decimal point. Since the decimal is being moved to the right, it is a negative exponent.
