A square root of 33 is a number that can be multiplied by itself to equal 33. The easiest way to calculate a square root is to use the square root button on a calculator. However, one can estimate the square root of 33 by noticing that the positive square root of 25 is five, and the positive square root of 36 is six, which suggests that the positive square root of 33 is somewhere between five and six.

Determine if the number is a perfect squareTo determine if the number is a perfect square, try to find a number that can be multiplied by itself to produce it. For example, 5 can be multiplied by 5 to produce 25, so 25 is a perfect square. If the number is not a perfect square, continue to the next steps.Find the closest perfect squaresTo generate a close approximation of the square root of a non-perfect square, determine which two perfect squares the number lies between. For example, if the number is 21, it lies between the perfect squares 16 and 25. Estimate the square root Pick one of the p..

Another condition for a figure to be classified as a polygon is that its sides must not cross each other. Some examples of polygons are a square, rectangle, hexagon, triangle and pentagon. Polygons also can be convex, concave irregular or regular figures. While concave polygons have reflex angles, convex polygons do not. Regular polygons have sides that are of equal length and all interior angles have equal measurement. Irregular polygons do not conform to this definition of regular polygons.

The length of an iron bar increasing as the temperature increases is an example of a positive correlation. An example of a negative correlation is that the volume of gas decreases as the pressure increases. If there is no relationship between the two variables, they are said to have no correlation or zero correlation. For example, if one variable changes and the second variable stays constant, these variables are said to have no correlation.

For a number to be classified as a prime number, it has to be greater than one and be a whole number. 31 is the 11th prime number in the list of prime numbers when beginning from the number 2, which is the first prime number. There are no other numbers apart from 31 and 1 that divide equally into 31, which makes it a prime number. Incidentally, the number one does not count as a prime number.

According to Math Is Fun defines a rational number as a number that is in the form p/q where p and q are integers, but q does not equal to zero. Whole numbers are rational because for any whole number "p," it can be represented as the ratio p/1.\nExamples of numbers that are irrational include the square root of 2 and the constant pi, approximated by 3.14. Decimals with an infinite expansion that do not repeat are considered irrational. According to Wolfram Math World, there are far fewer rational numbers on the real number line than there are irrational numbers.

The fraction 4/1 has a denominator of 1 and is thus an integer. It equals the integer 4. The fraction 10/2 is also an integer because it can be simplified to 5/1. This fraction also has a denominator of 1 and equals the integer 5.\nOn the other hand, 4/6 is not an integer. Its reduced form is 2/3, which has a denominator of 3.\nThe set of integers is comprised of the counting numbers (1, 2, 3, ...), as well as 0 and the negatives of the counting numbers.

Check the matrices for compatibilityIf the numbers of rows and columns in the opposite matrices do not match, the matrix product would be undefined. If they do match, proceed with multiplication.Multiply matching numbersAs an example, assume the row of the matrix A includes the set [9 8 2] and the column of matrix B contains [4 2 3]. Multiply 9 by 4, 8 by 2 and 2 by 3.Add the productsIn the example, the first result comes to 36 + 16 + 6, or 58. Start a new matrix and place the number 58 in the top left position.Repeat as necessaryContinue multiplying the rows and columns of matrix A and matrix..

Five common quadrilaterals have more specific properties: parallelograms, rectangles, squares, trapezoids and rhombuses. A trapezoid has one pair of opposite sides that are parallel. In a parallelogram, both sets of opposite sides are the same length and parallel to one another, while opposite angles are also equal. Rectangles are parallelograms where the angles all equal 90 degrees, and squares are rectangles with all sides of equal length. A rhombus is a parallelogram with four sides of equal length and is also called a diamond.

When a scientist graphs the results of an experiment, he graphs the manipulated variable on the x-axis of the graph. One common manipulated variable is time. The scientist controls the time at which he makes the measurements. The y-axis represents the response or dependant variable. Temperature is a common response variable.\nBecause it is easy to confuse variables in the experiment, About.com offers the mnemonic DRY MIX to help students. It translates: dependant, response, y-axis; manipulated, independent, x-axis. Another way to help keep these values from being confused is through rememberin..
