Answer:

Step-by-step explanation:

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{2}{3} }$ = - $\frac{3}{2}$ → A

Write the complex number z=-10+8i in polar form

jarptica [38.1K]

Hello :
the polar form is : z = |z |×e^(iθ)
z=-10+8i
|z | =√((-10)²+(8)²) =<span>√(164)
cos</span>θ = -10/√(164)
sinθ = 8/√(164)
find θ by arctan(8/-10)

Graph and label each of the ordered pairs in the coordinate plane. Then state the quadrant

Kamila [148]

The quadrants of the points are

Quadrant 1: Points A and D
Quadrant 2: Points E and H
Quadrant 3: Points G and J
Quadrant 4: Points C
x-axis: Point F
y-axis: Point B and I

<h3>How to determine the quadrants?</h3>

The points are given as:

A(2, 4) B(0, -3) C(1, -1)

E(-4,1) G(-3,-2) I(0, 2)

D(3, 3) F(2,0) H(-2, 3)

J(-1,-4)

Next, we plot each coordinate on a graph (see attachment)

From the attached graph, we have the following categories

Quadrant 1: Points A and D

Quadrant 2: Points E and H

Quadrant 3: Points G and J

Quadrant 4: Points C

x-axis: Point F

y-axis: Point B and I
