The line of sight is a line from the observer's eyes to a point far away. It is a line between two linear points between the transmitting antenna (in the case of a radio or television signal) and the receiving antenna when not obstructed by the horizon.. Why the height of the VHF radio antenna is important is because the VHF radio works according to the principle of sight line.

Reasons why the height of a VHF radio antenna is important is because VHF radios work by the line of sight principle.
Line of sight its a line from observers eye to a distant point.its a line between two points specifically the straight path between a transmitting antenna (as for radio or television signals) and receiving antenna when unobstructed by the horizon.

grigory [225]

Answer:

#include <iostream>

using namespace std;

int main()

{

int arr[]={3,-9,9,33,-4,-5, 100,4,-23};

int pos;

int n=sizeof(arr)/sizeof(arr[0]);

for(int i=0;i<n;i++){

if(arr[i]>=0){

pos++;

}

cout<<"Number of positive integers is "<<pos<<endl;

return 0;

}

Explanation:

create the main function in the c++ programming and declare the array with the element. Then, store the size of array by using the formula:

int n=sizeof(arr)/sizeof(arr[0]);

after that, take a for loop for traversing the array and then check condition for positive element using if statement,

condition is array element greater than or equal to zero.

if condition true then increment the count by 1.

this process happen until the condition true

and finally print the count.

Assume you are given three variables, revenue, expenses, and profit, all of type Money (a structured type with two int fields, d

Andre45 [30]

Answer:

if(revenue.cents - expenses.cents < 0){

profit.dollars = revenue.dollars - expenses.dollars - 1;

profit.cents = 1 - revenue.cents - expenses.cents;

}

else{

profit.dollars = revenue.dollars - expenses.dollars;

profit.cents = revenue.cents - expenses.cents;

}

Explanation:

We know that profit is given as: revenue - expenses from the question.

From the given expression above;

if(revenue.cents - expenses.cents < 0)

then profit.dollar will be revenue.dollars - expenses.dollars - 1; the 1 is to be carry over to the cent part. And the profit.cent will be 1 - revenue.cents - expenses.cents;

else the profit.dollars and the profit.cent is computed directly without needing to carry over:

profit.dollars = revenue.dollars - expenses.dollars;

profit.cents = revenue.cents - expenses.cents;

Multiply each element in origList with the corresponding value in offsetAmount. Print each product followed by a semicolon (no s

oee [108]

Answer:

Replace /* Your code goes here */ with

for(i =0; i<NUM_VALS; i++) {

printf("%d", origList[i]*offsetAmount[i]);

printf(";");

}

Explanation:

The first line is an iteration statement iterates from 0 till the last element in origList and offsetAmount

for(i =0; i<NUM_VALS; i++) {

This line calculates and print the product of element in origList and its corresponding element in offsetAmount

printf("%d", origList[i]*offsetAmount[i]);

This line prints a semicolon after the product has been calculated and printed

printf(";");

Iteration ends here

When web developers specify color values for text or backgrounds, they often represent RGB (red-green-blue) colors using a six-d

neonofarm [45]

Answer: A #3f107f.

Letter B would produce a lighter blue-purple color rather than a darker shade of purple. Letter C would produce a very light purple color. Letter D would produce a Black color, making it very dark and not in the range of being purple.

Letter A would produce a darker shade of purple. As explained in the way that the RGB color hexadecimal uses, the amount of each respective color is 2 digits for each color Red, Green, Blue respectively. By reducing the amount of each color in the RGB mode, the output will become a darker shade as the RGB mode is an ADDITITIVE type of color mode.

Answer:

A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a "complete" computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for "full" operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster
