Question

need help correcting my answers on two problems:
(6,1) and (-20,35)

also

(60, 5) and (-20, 35)

Answer 1

you'll need to post the full problem please

Answer 2

find out the distance between the pair of points. give an exact answer and where appropriate an approximation to there decimal place

Answer 3

thanks

Answer 4

you'll need to use the distance formula

\[\Large d = \sqrt{\left(x_{2}-x_{1}\right)^2+\left(y_{2}-y_{1}\right)^2}\]

Answer 5

for (6,1) and (-20,35) we see that

x1 = 6
y1 = 1


x2 = -20
y2 = 35

Answer 6

yes i know but my answers are off trying to figure out why or how it should look since i can't seems to figure out why

Answer 7

what answer did you get for the first one

Answer 8

yes I got that

Answer 9

the first one I got
\[D=\sqrt{2,500}\]

Answer 10

the second i got
\[D=\sqrt{1492}\]

Answer 11

the first one is too big

Answer 12

one sec

Answer 13

For for (6,1) and (-20,35)
\[\Large d = \sqrt{\left(x_{2}-x_{1}\right)^2+\left(y_{2}-y_{1}\right)^2}\]
\[\Large d = \sqrt{\left(6-(-20)\right)^2+\left(1-35\right)^2}\]
\[\Large d = \sqrt{\left(6+20\right)^2+\left(1-35\right)^2}\]
\[\Large d = \sqrt{\left(26\right)^2+\left(-34\right)^2}\]
\[\Large d = \sqrt{676+1156}\]
\[\Large d = \sqrt{1832}\]
Now you can simplify the radical to get...
\[\Large d = \sqrt{1832}\]
\[\Large d = \sqrt{4*458}\]
\[\Large d = \sqrt{4}*\sqrt{458}\]
\[\Large d = 2\sqrt{458}\]

Answer 14

hopefully you can see how I got all that

Answer 15

the book gives us an answer of \[\sqrt{45,6.708}\]

Answer 16

something is odd about that format

Answer 17

are you sure it says that?

Answer 18

yes

Answer 19

question though why do you go the opposite when replacing the formula with the problem. or does it matter.
meaning you did
X1 - X2
and not
X2-X1
