PLS HELPPP Express the complex number in trigonometric form. 3 - 3i

Mathematics
1 answer:
lesya [120]3 years ago
7 0
Z = a + bi
z = 3 - 3i

      |z| = √(a² + b²)
|3 - 3i| = √(3² + 3²)
|3 - 3i| = √(9 + 9)
|3 - 3i| = √(18)
|3 - 3i| = √(9 × 2)
|3 - 3i| = √(9)√(2)
|3 - 3i| = 3√(2)

tanΘ = b/a
tanΘ = ⁻³/₃
tanΘ = -1

Θ = arctan(-1)
Θ ≈ -0.8

z = 3√(2)(cos(-0.8) + i sin(-0.8))

The sum of two numbers is 12. The first number,x, is twice the second number ,y,
vlada-n [284]
Judging by the question at hand I generated this equation.
x+y=12
x=2y

I begin this question by plugging in the x=2y into the equation for x. 
So the new equation should be 3y=12. I then divide the entire equation by 3 to get y=4.

Next I plug y=4 into the equation, the new equation should be x+4=12. I then subtract 4 from both sides to get x=8.

The two numbers are :
x=8 y=4

What is the probability of choosing a burrito with cheese and a taco or a wrap with salsa?
neonofarm [45]
7:2
Step-by-step explanation:
Step one is to think about how often tacos are made. Tacos are made often. Now think about how often Wraps are made, not very often. After some research, the ratio is 7 burritos to 2 wraps. This would make the answer 7:2. Unfortunately tacos are more loved than Wraps.

A line passes through the points (9,6) and (6,5). What is its equation in slope-intercept form?
Tju [1.3M]

Answer:

Y=X/3+3

Step-by-step explanation:

M= Y2-Y1/X2-X1

  = 5-6/6-9

  = -1/-3

  = 1/3

sub x=6, y=5, M=1/3 into Y=MX+C

5=6/3+C

5=2+C

5-2= 2+C-2

3=C
