Q: Potassium counters the effects of sodium. Eat foods that contain high levels of potassium, like fruits and vegetables, or use vitamin and mineral supplements. Some examples of potassium-rich foods are: Raisins (1/2 cup): 618 mg Orange juice (1 cup): 496 mg Bananas: 422 mg Spinach (2 cups): 334 mg Eating 4 stalks of celery every day could help you reduce your blood pressure. Phytochemicals inside celery called phthalates can reduce blood pressure by relaxing the tissues in the walls of your arteries, which increases blood flow. So, chop up and eat 1 cup of celery for a healthy snack each day. Caffeine can increase blood pressure in people who rarely consume caffeine and especially in people who are already diagnosed with hypertension. Caffeine creates a big jump in the stiffness of arteries, causing the heart to pump harder which increases blood pressure. To see if caffeine affects your blood pressure, drink a caffeinated beverage and check your blood pressure within 30 minutes. If your blood pressure has increased by 5 to 10 mmHg, then caffeine likely causes an increase in your blood pressure. Confirm this with your doctor. Drinking alcohol can raise your blood pressure temporarily. Long-term heavy alcohol use can have a sustained impact on your blood pressure, so limit your alcohol intake. Different people have different alcohol limits. Ask your doctor how much you should drink. Drink alcoholic drinks that are lower in sodium and salt than others. This will make you more aware of the food you are consuming. Use an app or pen and paper to record quantities as well as what kind of foods you eat. You might be surprised by how much, or little, of one food you eat. Write down everything you eat, how much, and when you eat. After you have maintained this food diary for a week or so, review your entries and see if you are happy with what food you are eating. If there are any meals, snacks, or food items that you think you should cut out, do so. Keep up the food diary and use it as a source of information about your diet.
A: Eat 2,300-3,400 mg of potassium each day to balance your sodium levels. Increase your celery intake because it may improve blood flow. Consume less caffeine because it can worsen hypertension. Drink less alcohol because it raises your blood pressure. Keep a food diary so you know what you're eating.

Q: the lobster. Boiling lobster is one of the most common ways to cook it. Start by boiling water in a large pot. You want to make sure you have enough water in the pot to cover the lobster tails completely. For each quart of water, add 1 tablespoon of salt. Place the thawed lobster into the water, cover and let the water simmer for 5 minutes for each 4-ounce tail (and one extra minute for each additional ounce of lobster that you are cooking). You can tell the lobster is done when the shells are bright red and the meat tender if you poke at it with a fork. If you cut into the tail a properly cooked lobster will be just to the white. If translucent, put back and cook a little longer. the lobster. Set your oven on broil. Be aware that broiling is a very fast process, so keep a close eye on the lobster to make sure you don't burn it. Arrange the lobster tails on a broiler pan. Place them on the pan shell side up, and then broil it for only about 4 minutes. You want to keep the lobster meat about 5 inches away from the heat. If you are broiling very large lobster tails, you might want to split them lengthwise to make two servings from each. Turn them over. Brush with butter. Broil the other side 5 minutes more. Serve the tails. the lobster. One healthy way to cook lobster is to steam it. You want to start by putting a half inch of water in the pot with a tablespoon of salt and a tablespoon of vinegar. Put the lobsters in the pot. Cover the pot, and, if whole, let them steam for 10 minutes for a 1-pound lobster or 7-8 minutes per pound. Tails may take less time. You can also steam lobsters by placing them on a rack. Boil about two inches of water in a pot that is below the rack holding the lobster. Poaching is similar to steaming but the liquid is kept just below the boiling point. Added aromatics and seasonings enhance the flavor. To poach a lobster, prepare a poaching liquid in a large enough pot with cover, by adding lemon, chives, onion and celery to a little water. You can also add chicken or vegetable broth for added flavor. Seasonings can be added or substituted to your taste. You don't need more than and inch or two of your poaching liquid. Bring to a boil, lower heat to medium and simmer for a few minutes. Put the lobster in the poaching liquid, cover the pot tightly and simmer 7-8 minutes per pound. If the liquid is boiling use less time but check to make sure it's done. Try not to let the liquid boil. You will know it's done if an antenna or small leg pulls away easily when you tug on it and the tail meat has just gone to white. If it's still translucent, allow it to cook a few minutes longer. the lobster. To grill the lobster, find the cross that is located on the back of its head. Pierce it with a heavy knife. Cut down the back of the tail, splitting the lobster lengthwise.. Place the lobster on the grill. You will want to place the flesh side of the lobster down on the grill, and leave it there for about 8 to 10 minutes. There is no need to turn the lobster over. Before you grill it, brush it with butter or olive oil. You could also put a metal skewer through the tails before grilling them. . You can bake lobster tails or try baking lobster claws instead. First preheat heat your oven to 400F (204C). Bundle the claws together. Wrap them in a pocket of aluminum foil, and place them on a cookie sheet. You will bake them for about 10 minutes. You can tell the lobster claws are done when they look pink. Many grocery stores have lobster claws in the frozen food section.
A: Boil Broil Steam Poach the lobster. Grill Bake the lobster

Q: You can perform certain operations on a matrix to transform it while keeping it equivalent to the original. These are called elementary operations. To solve a 2x3 matrix, for example, you use elementary row operations to transform the matrix into a triangular one. Elementary operations include: swapping two rows. multiplying a row by a number different from zero. multiplying one row and then adding to another row. You want to produce zero in your second row, so multiply in a way that lets you do that. For example, say you have a matrix that looks like this:You can keep the first row and use it to produce zero in the second row. To do that, first multiply the second row by two, as follows: In order to get to zero for the first row, you may need to multiply again, using the same principle. In the example above, multiply the second row by -1, as follows:When you complete the multiplication, your new matrix looks like this: Next, add the first and second rows to produce zero in the first column of the second row. In the example above, add the two rows together as follows: At this point, you have a triangular matrix. You can use that matrix to get a new linear system. The first column corresponds to the unknown x, and the second column corresponds to the unknown y. The third column corresponds to the free member of an equation. For the example above, your new system would therefore look like this: Using your new system, determine which variable can be determined easily, and solve for it. In the example above, you'll want to "backsolve" moving from the last equation to the first when solving for your unknowns. The second equation gives you an easy solution for y; since the x has been removed, you can see that y = 2. Once you've determined one of the variables, you can substitute its value into the other equation to solve for the other variable. In the example above, replace the y with a 2 in the first equation to solve for x as follows:
A:
Understand elementary operations. Multiply the second row by a non-zero number. Multiply again. Add the first row to the second row. Write down the new linear system for the triangular matrix. Solve for one of the variables. Substitute to solve for the second variable.
