Answer:

Step-by-step explanation:

Hello, we know that the z complex solutions of

z^4=1

are

1, i, -1, -i

so, the solutions of z^4=16=2^4 are

Answer:

y=1.4x+6.8

Step-by-step explanation:

(-2;4) (-7;-3)

4=-2k+b

-3=-7k+b

7=5k

k=1.4

-2.8+b=4

b=6.8

I already know k and b so I can write an equation.

y=1.4x+6.8

What is the midpoint of the segment of the segment that would be created between points L and N on a graph?
il63 [147K]

Option A:

Midpoint of LN = (2, 3)  

Solution:

In the given graph we can find the coordinates of L and N.  

Coordinates of L = (–2, 3)

Coordinates of N = (6, 3)

Here, x_{1}=-2, x_{2}=6, y_{1}=3, y_{2}=3

Let us find the midpoint of the segment LN.

<u>Midpoint formula:</u>

$\text { Midpoint }=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)

                \begin{aligned}&=\left(\frac{-2+6}{2}, \frac{3+3}{2}\right)\\&=\left(\frac{4}{2}, \frac{6}{2}\right)\\&=(2,3)\end{aligned}

Midpoint of LN = (2, 3)  

Option A is the correct answer.  

Hence the coordinates of the midpoint of the line segment LN is (2, 3).

Complete the steps to find the value of x.<br> 72°<br> (7x + 24)
Elis [28]

Answer:

x=6.86°

firstly set them equal

to each other

(7x+24)=72°

subract 24 from both sides:

7x=48°

divide both sides by 7 :

x=6.857.....

this can be rounded to :

x=6.86°
