Question about Microsoft Windows XP Professional With Servise Pack 2 (e8503040) for PC

1 Answer

A rectangle with sides parallel to the x-y axes and its left-lower corner at (0, 0) is being painted. The rectangle may be thought of as a flat-screen display with almost infinite resolution; initially the entire rectangle is black. Two numbers are given 0 < h, v < 1 and then A vertical line is drawn dividing the horizontal sides of the rectangle in proportion h:1-h from the left. A horizontal line is drawn dividing the vertical sides of the rectangles in proportion v:1-v from the bottom up. These two lines divide the rectangle into four smaller rectangles. The upper left and the lower right sub-rectangles remain intact. The color of the other two rectangles is flipped (from black to white or from white to black) and now each of them is subject to the operation just performed on the bigger rectangle. This process continues (in principle) forever. Given a point in the original rectangle but not on the boundary of any rectangle that turns up in the process of painting, determine the color of the point. For example, you are told the resolution of the screen is 81x32, h=0.333333333333 and v=0.5 (These values must be asked for by your program). You are then asked to compute the colour of several points. The answer for each is displayed in the table below: x y Answer 16 30 black 16 25 black 16 12.0001 white 16 11.9999 black 16 7.987654321 white 16 7.0123456789 white

It would be "cheating" for anybody to do your "homework" from your computer-mathematics class, unless you submit your answer, saying that an EXPERT on FIXYA did all the work on your behalf.

This is a replacement player and it will not play some of my best disks I get 'wrong area code'.I live in Australia and bought the player from a reputable store.Thanks John Leigh.

Either the player or the disks are for a different region. The bright people who run the entertainment bussiness decide that it would be a good idea that only players and disks from certain areas of the world should only be used in their particular region. I quess they thought that no one moves or buys things through e-bay.
Try one of these resets
Open the tray.
- On your remote press '0000'.
- Press '0' to make it region free or whichever zone you want to set it to.
- The newly selected region will appear on the top left corner of the screen.
- Close the tray.

Turn on the player.
2. Open the tray.
3. Press the following sequence on the remote:
7 8 9 OK 0
4. The number 0 will appear on the lower left side of your screen.
5. Your player is now region free! Put in a DVD and enjoy! :)

How to mix two images ? specially at border of picture.

1. Open the first image.
2. Open the image you want to merge or mix with the first image or border.
3. Press Ctrl + A to select the entire image.
4. Press Ctrl + C to copy the selected image.
5. Click in the title bar of the image you opened first.
6. Press Ctrl + V to paste the second image over the first image.
7. If the Layer window is not displayed press theF7 function on your keyboard.
8. Make sure the top layer is highlighted or click on the layer to highlight it.
You should see the border around the image. If you want to hide part of the top image at the bottom lower left of the layer window you will see rectangle with circle which displays add layer mask when you hover the mouse cursor over it. Hold the Alt key and click on the Add Layer Mask Icon. This will hide the top image until you select the brush with a white color and paint the layer mask layer. The Layer Mask is the black rectangle next to the layer image which must have the white rectangle around it when painting with the brush. If you do not see the top image mixing with the bottom image make sure the black rectangle is selected or click on the black rectangle to select it. If the layered image is selected you will be painting it white and alter the image. If you revile part of the image when painting the mask you can hide it by changing the brush color to black and painting the reviled layer to hide it again. Layer masks are very powerful which you will need to look up in the help files for more information to gain full power of the tool.

Is a rectangle squared or cubed

Some wires got crossed here. A cube is a solid (a 3D object), whereas a rectangle and a square are 2D figures. You cannot compare a 2D figure with a 3D figure any more than you can compare say a parking lot and a highrise building.

A rectangle is a quadrilateral (closed polygon with 4 sides). In a rectangle, opposite sides are parallel and equal in length. In a rectangle all 4 angles are equal, each measuring 90 degrees.
All this is true for a square, except that all sides are now equal. So you can say that a square is a special kind of rectangle, namely, a rectangle with equal sides.
Hope it helps.

Write a system of linear inequalities whose solutuion region forms the given shape a rectangle

Hi wnhrtlywanda,
You can try this:
K>y>0, L>x>0, where K and L are any constants.
If you need a rectangle that is not parallel to the axes, use the formulae for the rotation of the axes and replace the small x, y in the above inequalities with the following values
x = XcosA - YsinA; and y = XsinA + YcosA
where capital X and Y denote the new x and y after rotation, A is the angle of rotation measured anticlockwise from the x-axis.
I sincerely hope this helps.

I had the same problem for awhile too.
The box is your call equalizer settings.  The descending line indicates "boost bass" and the ascending line indicates "boost treble"
This usually only shows when you have your BB headset connected, to change the settings:
-plug in your headset -make a call, (voice mail works good for this) -press your menu button -select "Enhance Call Audio"
-make your selection
You'll see your choice on the screen
Let me know if this helps 208E019D
