The midpoint is (blank,blank)

sveta [45]

Answer:

The answer to your question is Midpoint = (0, 1)

Equation of the bisector y = 2x + 1

Step-by-step explanation:

Data

P (-4, 3)

Q (4, -1)

Process

1.- Find the midpoint

Xm = (-4 + 4)/2

Xm = 0/2

Xm = 0

Ym = (3 - 1)/2

Ym = 2/2

Ym = 1

Midpoint = (0, 1)

2.- Equation of the line

slope = (-1 - 3) / (4 + 4)

= -4/8

= -1/2

But the new line is perpendicular so the new slope is

m = 2

Equation of the new line

y - y1 = m(x - x1)

y - 1 = 2(x - 0)

y - 1 = 2x

y = 2x + 1

2-sin^2x=2cos^2(x/2)

nadezda [96]

$2-\sin^2x=2\cos^2\dfrac x2$
$1+\cos^2x=1+\cos x$
$\cos^2x-\cos x=0$
$\cos x(\cos x-1)=0$

and this has solutions of $x=\dfrac{n\pi}2=\dfrac{(2k+1)\pi}2$ and $x=n\pi=2k\pi$ where $k\in\mathbb Z$ .
