Question

please help meeeee !!!! medal and fan <3

Answer 1

use the distance formula\[d =\sqrt{(x2-x1)^2 + (y2-y1)^2}\]

Answer 2

are u sure that is the right formula to use ?

Answer 3

x,1, y1 = -2, -4 and X2, y2 = 4, 3

Answer 4

whats so with that logic i was right ?

Answer 5

\[d= \sqrt{4-(-2)^2+(3-(-4)^2)}\]

Answer 6

\[d= \sqrt{4-(4) + (3-16)}\]

Answer 7

\[d= \sqrt{0 -13}\]

Answer 8

This ends up as a complex number d= 13i

Answer 9

have you studied complex numbers?

Answer 10

naw lol i just really cant get this question wrong :p

Answer 11

maybe I have made a mistake, its not in your four options

Answer 12

but those are the only options i have it has to be there :(

What does B is correct mean?

Answer 20

B is the right answer

Answer 21

Solution please

Answer 22

yea can u prove it ?

Answer 23

\[d=(A.B)=\sqrt{x2-x1^{2}+y2-y1^{2}}\]
This is the formula

Answer 24

wait @HelpOfTheGods

Answer 25

ok yea i seen that formula in my lesson so im thinking thats prob right since i have 0 clue lol

Answer 26

\[\sqrt{-2 - 4^{2}+-4-3^{2}}\]

Answer 27

@Black_ninja123 chose the points in reverse

Answer 28

\[\sqrt{36+49}\]

Answer 29

\[\sqrt{85}\]

Answer 30

Square root of 85 is 9.22

Answer 31

was anything I did @Black_ninja123 incorrect?

Answer 32

you said -2^2 is 4 but its actually -4

Answer 33

are you joking me? -2 x -2 = 4 not -4!

Answer 34

Use the calculator and its gonna tell you -4

Answer 35

I appreciate your help on this one @Black_ninja123

Answer 36

I entered (-2)x (-2) and it still gives me +4

Answer 37

enter -2^2

Answer 38

still +4

Answer 39

ok

Answer 40

I can change the rules of arithmetic for integers if you like
