False , because when the problem will be restricted to [0, 2) only, then there will be 2 polar points.
What is complex number explain with example?
- Complex numbers are the numbers that are expressed in the form of a+ ib where, a, b are real numbers and 'i' is an imaginary number called “iota”.
- The value of i = (√-1). For example, 2+3i is a complex number, where 2 is a real number (Re) and 3i is an imaginary number (Im).
In this question -
- The answer will be false because when the problem will be restricted to [0, 2) only, then there will be 2 polar points.
- The first r will be a positive, and the other r, of course, will be a negative.
- If the question has added a range where r is greater than zero (r > 0),this will be true because it only included the positive r.

The complete question is-
State True or false: As long as its argument is restricted to [0,2pi] the polar form of a complex number is unique.
Answer:
Step-by-step explanation:
Rewrite the Pythagorean Theorem equation in terms of 
.
Subtract b squared from both sides.
Answer:
Answer:
x=1 or x=−1

I think just 2
Answer:
To get the x-intercept we need the equation of the parabola;
the vertex form of the equation is given by:
y=a(x-h)^2+k
where:
(2,13) is the vertex:
Therefore;
y=a(x-2)^2+13
when x=0, y=5
Therefore the value of a will be:
5=a(0-2)^2+13
5-13=4a
4a=-8
a=-2
therefore the equation of the parabola will be:
y=-2(x-2)^2+13
y=-2x^2+8x+5
the x-intercept will be:
x=2-sqrt(7.5)
or
x=2+sqrt(7.5)
