The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Complex number is in the form z = a + bi, where a, b are real numbers.
Given the complex number z = 1 + 3i
In polar form: r = √(1² + 3²) = 3.16
Ф = tan⁻¹ (3/1) = 71.57⁰
The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]

Answer:
The correct answer is B. -3.
Step-by-step explanation:
To solve this problem, we need to plug in -3 for all of the values of x in the equation. If we do this, we get:
f(x) = 2x + 3
f(-3) = 2(-3) + 3
Now, we can just simplify the expression found on the right side of the equation using PEMDAS. First, we should perform the multiplication.
f(-3) = -6 + 3
Next, we should add our final two terms together.
f(-3) = -3
Therefore, the correct answer is -3.
Hope this helps!
Answer:
C
Step-by-step explanation:
Given
- x ≥ - 3
Multiply both sides by - 1 reversing the inequality symbol as a consequence of multiplying by a negative quantity, that is
x ≤ 3 → C
I'm guessing you're trying to simplify the equation since there is no other information lol
[(2x+y)-3]
So basically when you are trying to simplify equations you have to add the same variables together (In this case X & Y) But since there are no alike variables there really is nothing to add
So your answer would be 2x+y-3
Hoped this helped
