Is pi a surd?

NO!!!!

'pi' is an IRRATIONAL number.

Casually, an irrational number is one that recurs to infinity, AND there is NO regular order in the decimal digits.

e.g. pi = 3.141592.....

but pi ~ 3.14, or 3.1416, or 22/7 ( these are only approximations (~)).

However, 3.33333... is RATIONAL because, whilst the decimals go to infinity, they are are in a regular order of '3'.

What is the value of infinite?

There is NO value in 'Infinite'.

Because the number is so huge a value cannot be put on it. ; have an end number.

Remember the word 'infinite' means ' not ending/fished'. It does NOT finish.

However big you can make a number, if you add one(1) to it, it becomes bigger. This goes on 'ad finitum'.

What is the graph of the inequality in the coordinate plane?

The graph of an inequality in the coordinate plane represents a region that satisfies the inequality. For example, the inequality (y < 2x + 3) would be graphed by first drawing the line (y = 2x + 3) as a dashed line (indicating that points on the line are not included), and then shading the area below the line, which contains all the points that satisfy the inequality. The boundary line can be solid if the inequality is "less than or equal to" or "greater than or equal to."

What is M to the third power?

M to the third power, expressed mathematically as M³, means M multiplied by itself two more times, resulting in M × M × M. This operation raises the variable M to the exponent of three. The value of M³ will depend on the specific value of M.

How many 0 in the first 100 digits of pi?

In the first 100 digits of pi (3.14159...), there are no occurrences of the digit '0'. The first '0' appears much later in the decimal expansion of pi. Therefore, the count of '0's in the first 100 digits of pi is zero.

What is the function of glotis and epiglotis?

The glottis is the opening between the vocal cords in the larynx, playing a crucial role in sound production by regulating airflow during phonation. The epiglottis, on the other hand, is a flap-like structure that covers the glottis during swallowing, preventing food and liquids from entering the trachea and directing them into the esophagus. Together, they help facilitate breathing, speaking, and swallowing effectively.

How do you you solve 5x 12 3x - 20?

To solve the equation (5x + 12 = 3x - 20), first, rearrange the equation by moving all terms involving (x) to one side and constant terms to the other. Subtract (3x) from both sides to get (5x - 3x + 12 = -20), which simplifies to (2x + 12 = -20). Next, subtract 12 from both sides to obtain (2x = -32). Finally, divide both sides by 2 to find (x = -16).

What is the square root of x equal 0?

The square root of ( x ) equals 0 when ( x ) itself is 0. Mathematically, this can be expressed as ( \sqrt{x} = 0 ) implies ( x = 0 ). Therefore, the only solution to the equation ( \sqrt{x} = 0 ) is ( x = 0 ).

When is it graphed all the points that satisfy the equation are in a staright line?

When all the points that satisfy an equation are graphed in a straight line, the equation is linear. This typically takes the form of (y = mx + b), where (m) is the slope and (b) is the y-intercept. In this case, every solution represents a coordinate pair ((x, y)) that lies on that line, indicating a constant rate of change between (x) and (y). Linear relationships are characterized by their uniformity and direct proportionality.

Write an equation in the form y kx where k is the constant of variation if y varies directly as x and y 62.50 when x 10?

Since ( y ) varies directly as ( x ), we can express this relationship as ( y = kx ). Given that ( y = 62.50 ) when ( x = 10 ), we can substitute these values into the equation: ( 62.50 = k(10) ). Solving for ( k ) gives ( k = \frac{62.50}{10} = 6.25 ). Therefore, the equation is ( y = 6.25x ).
