We convert 2.3181818 to fraction as follows:
Let x = 2.3181818 . . . . . (1)
as can be seen, the repeating digits are 18
Multiply both sides of equation (1) by 1,000 to get
1,000x = 2318.1818 . . . . . (2)
Also, multiply both sides of equation (1) by 10 to get
10x = 23.181818 . . . . . (3)
Subtract equation (3) from equation (2) to get
990x = 2,295
Thus,
Polynomials are the expressions that contain two or more algebra terms - constants, variables and their powers of a particular variable. The simple example of a polynomial is
In the given question,
<span>9x3 – 4.1x2 + 7.3 is the polynomial because it has different powers of same variable x and does not contain any other variable.</span>
Answer:
Option B is correct, i.e. √13.
Step-by-step explanation:
Given is the complex plane and the coordinates of point A(-3, -2).
Distance from the origin of point A could be find using Distance formula given as follows:-
Distance = √{(-3-0)² + (-2-0)²}
OA = √(9+4)
OA = √13.
Hence, option B is correct, i.e. √13.
Answer:
800 square feet per minute
Step-by-step explanation:
<h3>Given</h3>
- arc AB of circle O is 1/4 of the circumference
- radius of circle O is 5
- pi is 3.14
<h3>Find</h3>
<h3>Solution</h3>
Since arc AB is 1/4 of the circumference, the central angle AOB will be 1/4 of a circle, so π/2 in radians. The area of a sector is given by
... A = (1/2)r²·θ
where θ is the central angle in radians and r is the radus.
The area is ...
... A = (1/2)·5²·π/2 = 25π/4
... A ≈ 19.625
The area of the sector is about 19.63 square units.
