Claudia hunts for 4 leaf clovers. She calculates that on average she has to look at 850 3 leaf clovers for every 4 leaf clover she finds. Which number shows about how many 4 leaf clovers she could expect to find in a field of about 8,500 clovers?
She should be able to find approximately 40 four leaf clovers.
Either that or my math sucks.
help! can someone teach me pi
Answer:
The number π (/paɪ/; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159. It is defined in Euclidean geometry[a] as the ratio of a circle's circumference to its diameter, and also has various equivalent definitions. The number appears in many formulas in all areas of mathematics and physics. The earliest known use of the Greek letter π to represent the ratio of a circle's circumference to its diameter was by Welsh mathematician William Jones in 1706.[1] It is also referred to as Archimedes's constant.[2][3]
Being an irrational number, π cannot be expressed as a common fraction, although fractions such as
22
/
7
are commonly used to approximate it. Equivalently, its decimal representation never ends and never settles into a permanently repeating pattern. Its decimal (or other base) digits appear to be randomly distributed, and are conjectured to satisfy a specific kind of statistical randomness.
It is known that π is a transcendental number:[2] it is not the root of any polynomial with rational coefficients. The transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge.
Ancient civilizations, including the Egyptians and Babylonians, required fairly accurate approximations of π for practical computations. Around 250 BC, the Greek mathematician Archimedes created an algorithm to approximate π with arbitrary accuracy. In the 5th century AD, Chinese mathematics approximated π to seven digits, while Indian mathematics made a five-digit approximation, both using geometrical techniques. The first computational formula for π, based on infinite series, was discovered a millennium later, when the Madhava–Leibniz series was discovered by the Kerala school of astronomy and mathematics, documented in the Yuktibhāṣā, written around 1530.[4][5]
The invention of calculus soon led to the calculation of hundreds of digits of π, enough for all practical scientific computations. Nevertheless, in the 20th and 21st centuries, mathematicians and computer scientists have pursued new approaches that, when combined with increasing computational power, extended the decimal representation of π to many trillions of digits.[6][7] The primary motivation for these computations is as a test case to develop efficient algorithms to calculate numeric series, as well as the quest to break records.[8][9] The extensive calculations involved have also been used to test supercomputers and high-precision multiplication algorithms.
Because its most elementary definition relates to the circle, π is found in many formulae in trigonometry and geometry, especially those concerning circles, ellipses, and spheres. In more modern mathematical analysis, the number is instead defined using the spectral properties of the real number system, as an eigenvalue or a period, without any reference to geometry. It appears therefore in areas of mathematics and sciences having little to do with the geometry of circles, such as number theory and statistics, as well as in almost all areas of physics. The ubiquity of π makes it one of the most widely known mathematical constants—both inside and outside the scientific community. Several books devoted to π have been published, and record-setting calculations of the digits of π often result in news headlines.

Use the Binomial Theorem to expand the expression (a - 4)5. Choose the correct polynomial.
Step-by-step explanation:
a⁵-5×a⁴×(-4)-10×a³×-(4)²-10×a²×(-4)³-5×a×(-4)⁴-(-4)⁵
=a³-20a⁴+160a³-640a²+1280a-1024
The required expansion of the binomial theorem will be as:
(a - 4)⁵ = a³-20a⁴+160a³-640a²+1280a-1024.
What is the Binomial Theorem?The binomial theorem states the principle for expanding the algebraic expression (x + y)ⁿ and describes it as the total of the phrases involving the unique exponents of the x and y variables. Each word in a binomial expansion has a coefficient, which is a numerical value.
The expression is given in the question following as:
(a - 4)⁵
[tex](a-4)^5=\frac{5!}{0!\left(5-0\right)!}a^5\left(-4\right)^0+\frac{5!}{1!\left(5-1\right)!}a^4\left(-4\right)^1+\frac{5!}{2!\left(5-2\right)!}a^3\left(-4\right)^2+\frac{5!}{3!\left(5-3\right)!}a^2\left(-4\right)^3+....[/tex]
⇒ a⁵-5×a⁴×(-4)-10×a³×-(4)²-10×a²×(-4)³-5×a×(-4)⁴-(-4)⁵
⇒ a³-20a⁴+160a³-640a²+1280a-1024
Therefore, the required expansion of the binomial theorem will be as:
(a - 4)⁵ = a³-20a⁴+160a³-640a²+1280a-1024.
Hence, the correct answer would be an option (A).

Hope this helps!!!
Please give me brainliest!!
Have a GREAT day and remember to take care of yourself!
The required trigonometric function is cos x.
Given that cosec x cot x [tex](1-cos^{2}x )[/tex].
By using trigonometric identities [tex]cos^{2}x + sin^2x=1[/tex],
that gives [tex]1-cos^2x=sin^2x[/tex]. -----(1)
By using the trigonometric functions,
cosec x = [tex]\frac{1}{sin x}[/tex] -------(2)
cot x = [tex]\frac{cos x}{sin x}[/tex] -----------(3)
By substituting equation 1, 2 and 3 in the given expression,
That implies, cosec x cot x [tex]sin^{2}x[/tex] = [tex]\frac{1}{sin x}[/tex] × [tex]\frac{cos x}{sin x}[/tex] × [tex]sin^2 x[/tex]
On algebraic simplifying gives,
cosec x cot x [tex]sin^{2}x[/tex] = [tex]\frac{cos x}{sin^2 x}[/tex] × [tex]sin^2 x[/tex]
On simplifying trigonometric functions gives,
cosec x cot x [tex]sin^{2}x[/tex] = cos x.
Hence, the required trigonometric function is cos x.
