Step-by-step explanation:
<u>Definitions</u>
Integer: A whole number that can be positive, negative, or zero.
Rational Number: A number that can be expressed as the ratio of two integers (where the denominator does not equal zero).
Irrational Number: A real number that <u>cannot</u> be written as a rational number.
Therefore, -8.2183 can be expressed as a <u>rational number</u>.
π is an <u>infinite decimal</u>, so it cannot be expressed as a rational number.
![\sqrt[\sf 3]{\sf 25}](https://tex.z-dn.net/?f=%5Csqrt%5B%5Csf%203%5D%7B%5Csf%2025%7D)
is an irrational number.
As 11 can be expressed as ¹¹/₁ then 9 + √4 is <u>rational</u>.
<u>Conclusion</u>
Therefore, the numbers that are irrational are:
Everyday, make her/him learn 3-4 tables. After 3 days, give him/her a 'prize' for it. If that does not work, try teaching him 1 by 1 and memorize it.
7.85 dollars because 3.14 is the price of one pound your buying 2.5 so you times 3.14 by 2.5
Answer:
f(x) = -7x² - x + 2
Step-by-step explanation:
Quadratic functions are set up in the form ax² + bx + c. f(x) = 0x² + 3x -3 is also set up in this format but 0x² would simplify to 0 which means the equation is actually f(x) = 3x-3 and does not fit in the quadratic function format. The other equations are also not set up in ax² + bx + c.
We will use the proper formula and solve.
-> A diameter of 48 / 2 = 24 feet as our radius
Area:
A = πr²
A = (3.14)(24)²
A = 1,808.64 ft²
The circle has an area of about 1,808.64 ft²
Circumference:
C = 2πr
C = 2(3.14)(24)
C = 150.72 ft
The circle has a circumference of about 150.72 ft
