Draw the shark's nostrils and the eyes using an egg-like shape. Draw the shark's mouth. Sketch out the shark's body from the outline. Darken the fins and tail. Draw the shark's gill slits using three curved lines. Erase unnecessary lines. Color the drawing."
article: Below the circle, draw a curved line extending to the left with a cone shaped end. These are characterized by being pointy and slightly curved. Add a curved line for the eyebrows. Real sharks do not have big eyes like these but it's okay to use your imagination for cartoon versions. Sharks are known to have really sharp teeth, you can draw its teeth using triangles. For a cartoon shark, you can divide the body into the posterior and anterior parts using a line straight across the body.

Write an article based on this "Select a calculator with matrix capabilities. Enter your matrix into the calculator. Select the Edit submenu. Select a name for your matrix. Enter the dimensions of your matrix. Enter each element of the matrix. Quit the Matrix function. Use the inverse key to find the inverse matrix. Convert your inverse matrix to exact answers. Most graphing calculators also have square bracket keys (on TI-84 it's 2nd + x and 2nd + -) which can be used to type in a matrix without using the matrix function."
article: Simple 4-function calculators will not be able to help you directly find the inverse. However, due to the repetitive nature of the calculations, an advanced graphing calculator, such as the Texas Instruments TI-83 or TI-86, can greatly reduce the work. First, enter your calculator's Matrix function by pressing the Matrix key, if you have one. On the Texas Instruments calculators, you may need to press 2nd Matrix. To reach the submenu, you may need to use the arrow buttons or choose the appropriate function key at the top of your calculator's keypad, depending on the layout of your calculator. Most calculators are equipped to work with anywhere from 3 to 10 matrices, labeled with letters A through J. Typically, just choose [A] to work with. Hit the Enter key after making your selection. This article is focusing on 3x3 matrices. However, the calculator can handle larger sizes. Enter the number of rows, then press Enter, and then the number of columns, and Enter. The calculator screen will show a matrix. If you previously were working with the matrix function, the prior matrix will appear on the screen. The cursor will highlight the first element of the matrix. Type in the value of the matrix you wish to solve, and then Enter. The cursor will move automatically to the next element of the matrix, overwriting any previous numbers. If you wish to enter a negative number, use your calculator's negative button (-) and not the minus key. The matrix function will not read the number properly. If necessary, you can use your calculator's arrow keys to jump around the matrix. After you have entered all values of the matrix, press the Quit key (or 2nd Quit, if necessary). This will exit you from the Matrix function and return you to the main display screen of your calculator. First, reopen the Matrix function and use the Names button to select the matrix label that you used to define your matrix (probably [A]). Then, press your calculator's inverse key, x1{\displaystyle x^{-1}}. This may require using the 2nd button, depending on your calculator. Your screen display should show A1{\displaystyle A^{-1}}. Press Enter, and the inverse matrix should appear on your screen. Do not use the ^ button on your calculator to try entering A^-1 as separate keystrokes. The calculator will not understand this operation. If you receive an error message when you enter the inverse key, chances are that your original matrix does not have an inverse. You may want to go back and calculate the determinant to find out. The first calculation that the calculator will give you is in decimal form. This is not considered "exact" for most purposes. You should convert the decimal answers to fractional form, as necessary. (If you are very lucky, all your results will be integers, but this is rare.) Your calculator probably has a function that will automatically convert the decimals to fractions. For example, using the TI-86, enter the Math function, then select Misc, and then Frac, and Enter. The decimals will automatically appear as fractions. Note: The calculator will not format the matrix until after the enter/equals key has been used (i.e. everything will be one line and not pretty).

article:
A grungy tub does not make for a relaxing bath. Start with a clean tub for best results. A quick way to clean a tub without a harsh chemical smell is to use baking soda. This cuts through soap scum without harsh smells. You can make a simple baking soda paste with 1 cup baking soda and add water for the desired consistency. Add the paste to the tub and let it dry. Wipe out the baking soda with a warm sponge, making sure to scrub any stubborn residue. You will want a water temperature warm enough to relax you but not hot enough to damage your skin or burn you. Try to get a temperature between 95-101 degrees Fahrenheit. Make sure the drain is closed and fill the tub. While the water is running, add desired infusions such as bubble bath or oils. The running water will disperse the bubbles and scents more easily. If you wait until the tub is full and the water is off, the oil may just sink to the bottom of the tub. Choose a scent that you like that makes you feel good. Good scents may be something like honey, almond, lavender, sea salt, vanilla. You can use bath bombs or epsom salt to help with relaxation. Epsom salt baths include many benefits including pain relief, stress relief, and skin care. Bath bombs come in many scents! They are also quite easy to make and can provide an interesting fizz to a normal bath.
