Linear Programming

Linear Programming Examples:

Now a canicule Beeline Programming became ,the algebraic address a lot of acclimated in analytic the array of problems accompanying with the management,from scheduling,to media selection, banking planning to basic budgeting,transportation and abounding others,with the appropriate appropriate that beeline programming apprehend consistently to maximise or to minimise some quantity.

Two possibilities arise at the band-aid of a linear-programming problems,

1-Simplex method,

2-Graphically,

Geometric Progression

The general form of geometric progression is:

a, ar, ar2, ar3, ar4, ..

Formula:

tn = arn-1

where a, the first term

r, the common ratio

Example:

Find the 7th term of the Geometric sequence 64, 16, 4....

Solution: a = 64, r = 16 / 64

r = 1/4

tn = ar7–1

t7 = ar7–1

= ar6

t7 = 64(1/4)6

= 64(1/4096)

t7 = 1/64

Hence the 7th term of Geometric sequence is 1/64

Fractions help

Some notes about fractions in math:(Free Fraction help)

The proper fraction, improper fraction is types of fractions & each type of fraction is differing in values. The proper fraction has large value in denominator & the improper fraction has little value in denominator.
The rules for adding fractions in math:

The following rules are helping the student for adding the fractions.
Rule 1: The least common multiple is determined if the denominator values of fractions are differing.
Rule 2: The least common multiple is multiplied with numerator value & add those values.
Rule 3: If they adding the fractions with mixed numbers means first alter the mixed number in to improper fraction.

Tangent

Tangent - the Slope & the Tangent Line:

What is a tangent?

A curve the line that touches the line at a point is called a s tangent. The idea of Tangent is very important in the field of geometry & its application. The tangent to a curve contains exactly one point of the curve.

Polygon defination

Regular polygon defination
In geometry, polygons pics fascinating topic for students. In this chapter they are seeing about polygon pics. Polygons are historically a plane figure. Polygons are bounded by a closed circuit, composed by arrangements of straight line segments. The line segments are known as edges or sides. These line segments are intersects exactly seven others.
Kinds of polygons:
There's seven types of polygons,

1.

Regular polygon
2.

Irregular polygon
