What is spherical geometry?

Spherical geometry is useful because it creates easy metrics that can be used to study complex three-dimensional shapes, such as spheres. However, there are some caveats to this branch of mathematics because some of the laws and rules of planar geometry don't apply to spherical geometry. For this reason, spherical geometry is sometimes confusing to math students, notes the University of Georgia Mathematical Education Program. As an example, there are no parallel or straight lines in spherical geometry. Circles are the basic shape utilized in this mathematical branch, which stands in stark..

What is the simplified square root of 48?

To simplify the square root of 48, the equation is rewritten as the square root of 16 times 3. The square root of 16, which is 4, is factored out, leaving the equation as 4 times the square root of 3. Since the square root of 3 cannot be further simplified, this value is the final simplified form. The square root of 48 is equal to about 6.92.

What shape has no parallel sides and no equal angles?

In a scalene triangle, the longest side is across from the largest angle, and the smallest side is opposite the smallest angle. A scalene triangle is a stable triangle. It is used in roof trusses, bicycle frames, automobiles, bridges and ramps. There is also a group of three muscles of different lengths in the human neck called the scalene muscles.

What is the formula for radius?

Another way to calculate the radius of a circle is by using the circumference. The equation using the circumference is the circumference of the circle divided by pi times two. Pi (Ï€) is a number that is approximately 3.14. The radius can also be calculated if the area is known; the radius is equal to the square root of the area of the circle divided by pi.

What does 777 mean?

The number 777 in numerology contains several ideas or attributes of a person including optimism, introspection, tolerance, inspiration and creative expression. It also contains the ability for the pursuit of perfection, effective communication, spiritual understanding, wisdom and scientific studies. Many people with 777 in their numerology chart are either artists or are people who are somehow related to the arts, perhaps in their mental pursuit of the art world. The person with 777 is also said to have a natural affinity for solving mysteries, most likely due to the person's ability to ..

What are Rf values?

Rf quantifies the distance that each compound of the analyzed mixture has traveled. The higher the Rf value, the longer the distance that a specific compound has traveled. The solvent front always moves further than any of the compound in the mixture. However, the compounds migrate differently depending on the type of mobile phase used because the migration speed depends on some characteristics of the solvent, such as polarity. The Rf value is characteristic for any chemical compound.

What is the slope of a line that is perpendicular to the x axis?

Dividing by zero does not yield a numerical answer. Because the inverse operation of division is multiplication, any division problem can be undone by a corresponding multiplication problem. For example, since six divided by two equals three, then three times two must equal six. However, if six divided by zero had a numerical answer, then the product of that number and zero would have to equal six, and multiplying any number by zero always yields zero.

What is 178 centimeters converted to feet?

The height of individuals is often measured in feet and inches. Sometimes, height is also mentioned in centimeters. Heights of inanimate objects are also measured in feet, inches, centimeters and meters. This makes it imperative to know how to convert one unit of length into another unit. In mathematics and physics, students are often required to convert these units from one to the other.

What is the formula to find the area of a sector?

Certain information needs to be available to use the formula and find the area. The first thing that needs to be known is the degree of the central angle of the sector. The central angle is created at the point in the center of the circle where the two radii that mark the edges of the sector meet. The length of the radius of the circle also needs to be known to solve for the area of the sector.\nIf the radius of the circle is 10 inches, and the central angle of the sector is 90 degrees, the area of the sector can be found as follows: 90/360 * (3.14 * 10^2). Following the order of operations, t..
