On the CallCenterReport worksheet, add formulas that will summarize the issues for the department entered in cell B3. In cell B6
grin007 [14]

Answer:

In cell B6, formula =INDEX(INDIRECT($B$3),A6)

CallCenter Worksheet Details:

The image of the CallCenter Report worksheet for reference to the question asked is attached below.

Explanation:

Firtsly, an absolute reference in Excel refers to a reference that is "locked" so that rows and columns won't change when copied. To do this,we put a $ dollar sign ( =A$1,) before the row coordinate to lock only the row.

A relative reference in Excel is a cell address without the $ sign in the row and column coordinates example A1.

Having known what absolute and relative reference are, we wlil write the below formula in cell B6 that will later be copied to cell B9:

: =INDEX(INDIRECT($B$3),A6)

The light you shoot in will dictate what shutter speeds to use.
Nesterboy [21]

Answer:

The three things that will determine your exposure are film speed, aperture and shutter speed. The speed of the film dictates how much light the film needs. The aperture controls how much light comes through the lens. And the shutter speed then controls how much of that light hits the film. These three things always work together to produce your image.

The shutter speed, sometimes known as exposure time, determines the amount of time your film is exposed to light when taking a photograph. So, you always need to balance your aperture and shutter speed to get a correct exposure.

The general rule is you need to shoot with at least 1/60 to get sharp images when shooting handheld. It is best to use a tripod if you want to shoot with a slower exposure time as this will help reduce any camera shake.

Fast Shutter

Fast speeds are really good for freezing fast-moving subjects. You need to make sure you are using a fast exposure time if you are trying to take a sharp image of a fast subject. Different cameras have different options but commonly you can choose something like 1/500.

Higher ISO film will also allow you to utilise the faster shutter speeds as they are more sensitive to light.

Slow Shutter

Slow shutter speeds will visibly record motion. They are often used to create the effect of motion in an image. A moving subject captured with a slow exposure time will be captured as a blur across the image. Slow exposure times are also necessary when taking photos at night. They allow you to get enough light to expose your image correctly.

Be careful when using slow exposures without a tripod. The slower the shutter the more likely that you will have visible camera shake in the image.

Reading Shutter Speeds

Shutter speed is measured in fractions of a second. So, for example, 1/60 is read as one-sixtieth of a second. The bigger the second number in the faster the speed.

Typical shutter speeds you will see are; 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250 and 1/500.

Assume that a function named swapdoubles has been defined and is available for use in this exercise: that function receives two
Nata [24]

Answer:

C++ Code:

void sort3(double &a, double &b, double &c)

{

   if(a > b)

       swapdoubles(a,b);

   if (b > c)

       swapdoubles(b,c);

   if (a > b)

       swapdoubles(a,b);

}

Explanation:

To change the values of a,b,c within the function, we pass the values by reference. Let us assume that number a = 3.14, b = 2.71, c = 3.04. Since a > b, values of a and b will be swapped.Now a = 2.71 and b = 3.14. Similariy, since b > c, they will be swapped. This way, we move the largest number to its correct position in the first two steps. If there are only three numbers, and the largest number is in its correct position, then for the two remaining numbers, we will only need atmost one swap to exchange their positions. hence, we perform a comparison of a > b once again to see if the b is smaller than a. if its not, then all a,b,c are in sorted order.

sasho [114]

Answer:

Kernel.

Explanation:

An operating system platform is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system (OS) is essentially an interface between the computer’s hardware and all the software applications (programs) running on it.

Some examples of an operating system are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM, etc.

Kernel is part of the operating system core. It is responsible for controlling security, managing the file system, and providing a platform for applications to run on.

Basically, the kernel is the foundational or fundamental layer of the operating system (OS) and as such it is loaded into memory whenever the computer system starts to boot i.e the kernel must always reside in the memory of a computer because it is saddled with the responsibility of managing computer resources such as the central processing unit (CPU), peripheral devices, random access memory (RAM) and input/output instructions from software programs.
