Why does a number to the zero power equal one?

When a number such as 2 is raised to different powers, a particular pattern is seen as the exponent changes:\n\n\n2^6 = 2*2*2*2*2*2 = 64\n2^5 = 2*2*2*2*2 = 32\n2^4 = 2*2*2*2 = 16\n2^3 = 2*2*2 = 8\n2^2 = 2*2 = 4\n2^1 = 2\n\n\nAs the exponent value moves from 6 to 1, we see that the resulting values are reduced, consecutively, dividing by 2: 64/2 = 32, 32/2 = 16, 16/2 = 8, 8/2 = 4 and 4/2 = 2. Extrapolating from this pattern, an exponent of 0 will result in an answer of 2/2 = 1, proving 2^0 = 1.\n\nThe number 2 was used to provide an example; however, this concept applies to all nonzero numbers.

How do you determine if two angles are supplementary?

Though angles do not have to be adjacent to be supplementary, because supplementary angles pair to make straight lines, they can be used to find the measurements of unknown, adjacent angles. Care must be taken, however, not to confuse their properties with those of complementary angles, which are closely related but pair to make right angles and add up to 90 degrees.

How is geometry used in fashion design?

Fashion designers routinely make use of geometrical implements such as T-squares and rulers, with straight lines being a common sight in contemporary fashion. These include crisp, straight-edged collars and A-line dresses that flare out from the body.Particularly in prints, checkers, bold zigzags and grids are common. Some designers aim for a disguising of the natural figure with such geometry, often by combining straight-edged garments with grid-like patterning.Geometrical principles underpin fashion design more generally. For example, garments must be balanced on the body around a central fu..

What are perpendicular lines?

Another fact about perpendicular lines is that their slopes are negative reciprocals of one another. The two slopes multiplied together always produce an answer of -1. The formula for slope is rise divided by run. If a line goes through point (x1y1) and point (x2y2), the formula for its slope is set up as y2 - y1 / x2 - x1. If the slope of one of the two perpendicular lines is 1/2, the slope of the other is -2.

How do you simplify complex fractions?

Find common denominators for the numerator and denominatorConsider the example (6 + 1/x) / (8 + 4/x^2). Notice that the common denominator for the numerator term is x, and that the denominator's common denominator is x^2. Multiply other terms in an equivalent way to combine like terms. Write the example problem in this way: (6x/x + 1/x) / (8x^2/x^2 + 4/x^2).Combine like terms in the numerator and denominatorAdd like terms in both the numerator and the denominator. Write the next step for the example problem as such: [(6x + 1) / x] / [(8x^2 + 4) / x^2].Flip the denominator, and multiply to..

What are alternate exterior angles?

Mathematicians use properties of alternate exterior angles to find the measurement of an angle or to determine the relationships between intersecting lines.\nFor example, in a drawing of two parallel lines intersected by a transversal, a person uses the alternate exterior angle value to find the measure of an exterior angle. This theorem also solves the measure of a supplementary angle, as well.

How do you read a protractor?

Place the protractor on the angleThe center point of the protractor is at the bottom in a circle. Place the point on the angle and line up the bottom line of the protractor with the straight edge that connects to the angle.Find the intersectionIdentify where the other side of the angle intersects with the protractor. Mark the line or make note of it.Read the angleAngles range from zero to 180 degrees. The protractor runs from zero to 90 and 90 to 180 on both sides to simplify measurement. If an angle is smaller than 90 degrees, the degree number is shown in the top left or lower right. For an ..

What are some uses for a calculator?

There are numerous types of calculators, and many people use a simple electronic calculator to perform basic arithmetic. This type of calculator typically shows the result on an LED screen and uses batteries, solar power or both.\nPhysicists and engineers use scientific calculators, which are much more advanced than standard calculators. These calculators have large screens that can display graphs or multiple lines of calculations. Accountants and other finance professionals also use specialized calculators, known as financial calculators, which can calculate interest on loans or savings and q..

What is a cubic centimeter equal to in volume?

The use of either cubic centimeter or milliliter varies among different countries and industries. In the scientific field, most favor the use of milliliters over cubic centimeters. In the United States, both automotive and medical fields still prefer the use of cubic centimeter. Outside the United States, much of the automotive industry has switched to using liters. In the United Kingdom, the use of millilitres is preferred in the medical field, but cubic centimetres is still the choice in the automotive industry. A majority of the other English-speaking nations have the same preferences as th..
