How do you use a simple interest calculator?

Simple interest is calculated by multiplying the initial investment amount, called the principal, by the interest rate by the amount of time the money is invested, expressed in years. This amount is then divided by 100 to get the amount of interest earned.\nA simple interest calculator performs the operation, [Simple interest = (P x R x T) /100], automatically. Some calculators also calculate the other factors of the equation. If a person provides the principal amount, the interest rate and the amount of interest desired a calculator can determine the length of time required to achieve the des..

What is the antiderivative of sinx?

The integral of sin(x) is found by using the integration techniques known as integration by parts or substitution. Integration by substitution is also known as using the chain rule for derivatives in the reverse. The value for the integral of sin(x) is found by directly plugging it into a graphing calculator or plugging in the value of x to the equation -cos(x) + c.

What are the methods for graphing ellipses?

In the formula for graphing the ellipse, the variable h is the x-coordinate of the center, k is the y-coordinate of the center, a is the distance from the center to the edge of the ellipse along the major axis, and b is the distance from the center to the edge of the ellipse along the minor axis. The major axis of the ellipse is the line that runs through the center of an ellipse at its longest part, whereas the minor axis is the line that runs through the center of the ellipse perpendicular to the major axis.\nThe points where the major axis intersects the ellipse are called the vertices, whi..

What are the factors of 120?

The first two numbers on any factor list should be the number itself and the number 1, which is a dividing factor for every number. Then, it helps to look at the last digit. If it is 2, 4, 6, 8 or 0, that number is divisible by 2. Dividing 120 by 2 yields 60, which becomes the fourth factor.\nTesting a number's divisibility by three involves adding up the digits. In the case of 120, 1 + 2 + 0 = 3. If the sum is divisible by 3, so is the larger number. The number 120 passes this test, and so 3 is a factor. Dividing 120 by 3 yields the sixth factor, 40, according to Math Warehouse.\nTesting..

What is the function of Pi?

Pi is an irrational number that does not have a specific value that can be shown. Often, the value is rounded to 3.14 or shown as the fraction 22/7. Outside of mathematics, pi is also used in physics for calculating measurements such as angular velocity. Pi is also necessary when converting between degrees and radians, as one radian is equal to pi/180 degrees.

How many edges does a sphere have?

Edges interconnect the faces of an object. A cube is a prime example of a geometric figure containing multiple faces. A cube possesses a total of 12 faces. A sphere is defined as a round, three-dimensional geometric figure in which every point of the surface of a sphere is equidistant from the center. A sphere differs from a circle because a circle is not three-dimensional. A ball is the standard example of a sphere.

What is a way of solving polynomial equations by factoring?

All factors set to zero are solved by setting the X on one side and the answer on the opposite side. The factoring strategies mentioned involve identifying the greatest common factor (GCF) of the polynomial and dividing every term of the polynomial by the GCF. If there is no GCF for all the terms in the polynomial, and the polynomial has four terms, the terms are factored by grouping. The first two terms are grouped together and the same is done to the last two terms.\nThe next step is to factor out a GCF from each of the binomials, which are then used to factor out a common binomial. The Zero..

How do you calculate the square feet of an area?

Find the dimensionsTwo perpendicular measurements are needed to calculate the area of most shapes. On a rectangle, measuring the sides can give you the dimensions you need because one side can be the length and the adjacent side can be the height. On many other shapes, measuring one or more flat sides and then the height (or greatest distance taken with a perpendicular line) often works.Plug them into a formula for areaFor rectangles, multiply the length (or base) by the width (or height). The units are also multiplied. For example, if you measured a wall at 12 feet long by 8 feet high, the ar..
