Rectangle RSTU and the image R’S’T’U’ are graphed on the coordinate grid below.
Ksju [112]

The rectangle  R’S’T’U’ is a 90° counterclockwise rotation of RSTU so options (A) and (C) will be correct.

<h3>What is a rectangle?</h3>

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Given the rectangle RSTU if we plot it then it becomes a major horizontal rectangle.

If we transpose into R’S’T’U’ then it rotates 90 degrees counterclockwise and becomes a major vertical ractangle.

Hence the rectangle RSTU will rotate 90° counterclockwise to form  R’S’T’U’.

(3-4i)(-2-21) multiply
evablogger [386]

Answer:

-69 +92 i (here 'i' is imaginary value)

Step-by-step explanation:

step:-

Given (3-4 i)(-2-21)

on multiplication, we get

(3-4 i)(-2-21) = 3(-2) -3(21) - 4 i (-2) +4 i(21)

                    = -6 -63 + 8 i +84 i

                    = -69 +92 i

-69 + 92 i is a complex number.

real part x = -69

imaginary part y = 92

PIT_PIT [208]
Hello,

4x²-x-3=0
==>(2x)²-2*1/2*x+1/4-3-1/4=0
==>(2x-1/2)²-13/4=0
==>(4x-1)²-13=0
==>(4x-1-√13)(4x-1+√13)=0
==> x=(1+√13)/4 or x=(1-√13)/4
