(-2-3i)-(3+9i)
= 6i-5
Pachacha [2.7K]3 years ago

Answer:

13

Step-by-step explanation:

Expressing the complex numbers in coordinate form

- 2 - 3i → (- 2, - 3)

3 + 9i → (3, 9)

To calculate the distance d use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (3, 9)

d = \sqrt{(3+2)^2+(9+3)^2}

   = \sqrt{5^2+12^2}

   = \sqrt{25+144}

   = \sqrt{169}

   = 13

wendy is logging the number of video game levels she wins per hour. she has determined the function to be f(x) = 6x + 9, where x
True [87]
Since we are talking about real quantities (hours), x should be positive. Also, you need to take into account that Wendy needs to play in order to win game levels.
Therefore the domain will be: x > 0

Complete the square to find the vertex of this parabola.PLEASE HELP!!
Paladinen [302]

Answer:

(1, 5 )

Step-by-step explanation:

Given

x² - 2x + y - 4 = 0 ( add 4 to both sides )

x² - 2x + y = 4

Complete the square on x² - 2x

add ( half the coefficient of the x term )² to both sides

x² + 2(- 1)x + 1 + y = 4 + 1, that is

(x - 1)² + y = 5

Subtract (x - 1)² from both sides

y = - (x - 1)² + 5

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

y = - (x - 1)² + 5 ← is in vertex form

with vertex = (1, 5 )
