Answer:

A. Document camera

Explanation:

Document cameras, which are also known as visual presenters or visualisers, digital overheads, or docucams. They are real-time image capture devices for displaying an object to a large audience. Just like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, simply put, high resolution web cams, that is mounted on arms so as to facilitate their placement over a page.

This makes it easier and convenient for a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches.

In Theory, the document camera can be used to display all objects.

Gwen only needs to place her photo under a document camera and deliver her speech while the image will be displayed for the class.

Which of the following galaxy types is most likely to be clearly identifiable, regardless of orientation? SBc
Reil [10]

Answer:

The most likely galaxy type to be identifiable regardless of orientation is: Irr

Explanation:

The Irr galaxies don't have a discernable or usual shape; that is why it is relatively easy to identify.

When we talk about E type galaxies, this statement proves itself by the way the cumulus of stars compounds the galaxy. The elliptical galaxies have the form of ellipses, with a reasonable distribution of stars. The degree of eccentricity is the number that complements the E letter; that's why E0 galaxies are almost spherical, while E7 is considerably elongated.

SBc, SBa galaxies are spiral; this means it can be flat in some angles difficulting their identification process; in this case, the last letter means the way the arms display their form, with "c" having a vague form and "a" well-defined arms. That's why in some angles can be mistreated as another type of galaxy.

A shop will give discount of 10% if the cost of purchased quantity is more than 1000. Ask user for quantity suppose, one unit wi
Mamont248 [21]

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

int main(){

   int qty;

   float discount = 0;

   cout<<"Quantity: ";

   cin>>qty;

   int cost = qty * 100;

i f (cost > 1000) {        discount=cost * 0.10;        }

   cout<<"Cost: "<<cost - discount;

   return 0;

}

Explanation:

This declares the quantity as integer

   int qty;

This declares and initializes discount to 0

   float discount = 0;

This prompts the user for quantity

   cout<<"Quantity: ";

This gets input for quantity

   cin>>qty;

This calculates the cost

   int cost = qty * 100;

If cost is above 1000, a discount of 10% is calculated

i f (cost > 1000) {        discount=cost * 0.10;        }

This prints the cost

   cout<<"Cost: "<<cost - discount;
