Answer:
We kindly invite you to see the result in the image attached below.
The number in polar form is .
Step-by-step explanation:
A complex number is represented by elements of the form , for all , . The first part of the sum is the real component of the complex number, whereas the second part of the sum is the imaginary component of the complex number. The real component is located on the horizontal axis and the imaginary component on the vertical axis.
Now we proceed to present the point on the graph: (, ) We kindly invite you to see the result in the image attached below.
The polar form of the complex number is defined by:
(1)
Where:
- Magnitude of the complex number, dimensionless.
- Direction of the complex number, measured in radians.
The magnitude and the direction of the complex number are defined by the following formulas:
Magnitude
(2)
Direction
(3)
If we know that and , then the polar form of the number is:
The number in polar form is .
Rewriting input as fractions if necessary:
7/1, 343/1
For the denominators (1, 1) the least common multiple (LCM<span>) is </span>1.
Therefore, the least common denominator (LCD<span>) is </span>1.
<span>Rewriting the original inputs as equivalent fractions with the </span>LCD:

The ideal radius Alan must control is cm.
<h3>Define perimeter of circle.</h3>
The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The area of a circle determines the space it takes up. A circle's diameter is equal to the length of a straight line traced through its center. Usually, it is stated in terms of units like cm or m.
Given data -
Perimeter of circular plate = 10 cm
We know that perimeter of a circle is 2r
Therefore 10 = 2r
r = 5 cm
The given error Alan can make is +-1 cm.
Minimum radius is given by
2r = 10 - 1
r =
r = 5 -
Maximum radius is given by
2r = 10 + 1
r =
r = 5 +
The ideal radius Alan must control is cm.

Answer:
3. 10 - 5 is 5. so that is the difference. difference means subtraction.
4. 108 - 30 = 78. so she can move 78 degrees miore after therapy because 108 minues 30 is 78
5. 99 because 180 - 81 = 99. there is always 180 degrees in a line angle.
6. 130 degrees. 25 + 25 = 50 so 180 minus 50 equals 130
