Question

What is the distance between points E and F?

Answer 1

Can u plz tell me the coordinates of E nd F? @dedderick

Answer 2

e: -3,2 and f:-2,4

Answer 3

ya good:)

Answer 4

the distance d between the points A=\((x_1,y_1)\) and B=\((x_2,y_2)\) can be found from the formula
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
Does that help? @dedderick

Answer 5

yes

Answer 6

i got 5.38

Answer 7

ya. i got 5.385=5.39

Answer 8

how will i put that in a square root

Answer 9

put what?

Answer 10

all the answers choices are square roots

Answer 11

hmm.
\(\sqrt{(5.38)^2}\)

Answer 12

not a answer choice

Answer 13

what is (5.38)^2=?

Answer 14

28.94

Answer 15

wait a sec.
\(d=\sqrt{(-2-(-3))^2+(4-2)^2}\)
\(=\sqrt{(-2+3)^2+(4-2)^2}\)

Answer 16

i got 4.12

Answer 17

I made a mistake when I calculated 5.39.
