In the complex plane, the rectangular coordinates (x, y) represent a complex number. Which statement explains why polar coordinates (r, θ) represent the same complex number?
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction).
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction).
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction).
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction)
Answer:
The correct option is;
r = √(x² + y²)
θ = tan⁻¹(y/x)
Step-by-step explanation:
The rectangular coordinate of a complex number on the complex plane is given as (x, y)
Given that the complex number is represented by a point on the plane, we have;
The distance, r, of the point from the origin, (0, 0) is r = √(x² + y²)
The direction, θ, by which we rotate to be in line with the point on the complex number is given by tan⁻¹(y/x)

Complete the table below for the function y = -3x+7
Answer:
(x,y)--> (2,1), (4, -5), (7, -14), (9, -20), (11, -26)
Step-by-step explanation:
y = -3x + 7
substituting x-values in y= -3x + 7
x = 2
y= -3 × 2 + 7
= -6 + 7
= 1
x=4
y= -3 × 4 + 7
= -12 + 7
= -5
x=7
y= -3 × 7 + 7
= -21 + 7
= -14
x=9
y= -3 × 9 + 7
= -27 + 7
= -20
x=11
y= -3 × 11 + 7
= -33 + 7
= -26
The table for the linear relationship, y = - 3x + 7 is shown below
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
Given that,
A equation of a line,
y = - 3x + 7
And Values of x,
2, 4, 7, 9, 11
Now, values of y for particular values of x
When x = 2
y = - 3 × 2 + 7
= 1
When x = 4
y = - 3 × 4 + 7
= -5
When x = 7
y = - 3 × 7 + 7
= - 14
When x = 9
y = - 3 × 9 + 7
= -20
When x = 11
y = - 3 × 11 + 7
= -26
The table for values of y
x: 2 4 7 9 11
y: 1 -5 -14 -20 -26

What is the rate of change, I’m confused
Answer:
for every increase in x, y increases by 7
Step-by-step explanation:
Use substitution to determine the solution of the system of equations. Write the solution as an ordered pair.
x + 2y = 14
y = 3x − 14
The value of x is 6 and the value of y is 4 for the expressions.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the two linear equations are x + 2y = 14 and y = 3x − 14. Equations can be solved as below,
x + 2y = 14
y = 3x − 14
Substitute the value of y in the first equation,
x + 2y = 14
x + 2 ( 3x - 14 ) = 14
x + 6x - 28 = 14
7x = 42
x = 6
The value of y will be calculated as:-
y = 3x - 14
y = ( 3 x 6 ) - 14
y = 18 - 14
y = 4

What percentage of total hours were spent skiing?
Soccer 5
Jogging 20
walking 10
skiing 5
football 10
Answer:
10%
Step-by-step explanation:
5/50=x/100
5×100=500
500/50=10
x=10
10%
Percentage of total hours were spent skiing is 10%
What is the percentage?Percentage is defined as a relative value indicating 100th parts of any quantity. It is denoted by symbol of %.
Given that,
Soccer = 5 hours
Jogging =20 hours
Walking =10 hours
Skiing = 5 hours
Football = 10 hours
Total hours were spent all activity = 5+20+10+5+10=50
Let, percentage of total hours were spent skiing = x
5/50=x/100
5×100=500
500/50=10
