Question

What is the length of ac ? Round to the nearest hundredth.

Answer 1

distance formula

Answer 2

d=√(x1-x2)²+(y2-y1)²
d=√(-1-3)²+(-2-2)²
is that right ? im not sure how to find x and y

Answer 3

its not right

Answer 4

lets do step by step.

first tell me the coordinates of points A and C :

A = ?
C = ?

Answer 5

A-(-1,3)
C-(2,-2) ?

Answer 6

A correct.
C wrong

Answer 7

oops ! im wrong, you're correct actually :)

Answer 8

okkk (:

Answer 9

A (-1, 3) C (2, -2)
x1 y1 x2 y2

Answer 10

apply distance formula now

Answer 11

\(\sqrt{(x1-x2)^2+(y1-y2)^2}\)

Answer 12

d=√(x1-x2)²+(y1-y2)²
d=√(-1-2)²+(3-(-2))²
d=√(-3)²+(5)²
d=√9+25
d=√34

Answer 13

perfect !

Answer 14

Okkk (;. Soo how would i round it to the nearest tenth ?

Answer 15

sorry hundreth

Answer 16

plug it in ur calculator

Answer 17

what do u get when u take square root of 34 ?

Answer 18

oopss i forgot that part. Its 5.83 (: . ! ii Got It . THanksss Sooo Much ! 'ii Leanred something new !

Answer 19

nice :)))

Answer 20

ii have one more question on my assignment. Does coordinates on a triangle tell you what kind of triangle it would be ?

Answer 21

would it be scalene because they all have diferent points ?

Answer 22

know what, every point in grid will have different numbers.

Answer 23

so having different points is okay :) it wont give us any clue about the kind of triangle

Answer 24

we need to calculate distance of all 3 sides, and see

Answer 25

Ohhh Yess .. ^^That makes sense . ... how do i do that ?

Answer 26

use distance formula 3 times, and find the distance of each side

Answer 27

start with the finding the length of left side joining points : (-10, 8) and (-10, 3)

Answer 28

apply distance formula for those two points

Answer 29

okkik . ill do it paper and be back in a sec.

Answer 30

take ur time :) il he here

Answer 31

*be

Answer 32

so i got
(-10,8)(-10,3)
√5
(-10,8)(-6,5)
√-1
(-10,3)(-6,5)
√-6

Answer 33

check ur signs again

Answer 34

you would never get a negative sign inside radical, as these are lengths

Answer 35

im not sure what i did wrong because i did this
(-10,8)(-10,3)
x1 y1 x2 y2
d=√-10-(-10)+(8-3)
d=√0+5
√5
(-10,8)(-6,5)
d=√-10-(-6)+(8-5)
d=√-4+3
√-1

Answer 36

Below correct way, see if it helps :-

(-10, 8)(-10,3)\
\(\sqrt{(-10--10)^2+(8-3)^2} \)
\(\sqrt{(0)^2+(5)^2} \)
\(5\)

(-10,8)(-6,5)
\(\sqrt{(-10--6)^2+(8-5)^2} \)
\(\sqrt{(-4)^2+(3)^2} \)
\(\sqrt{16+9}\)
\(\sqrt{25}\)
\(5\)

(-10,3)(-6,5)
\(\sqrt{(-10--6)^2+(3-5)^2} \)
\(\sqrt{(-4)^2+(-2)^2} \)
\(\sqrt{16+4}\)
\(\sqrt{20}\)
\(4.47\)

Answer 37

looks u forgot to square inside the radical, other than that ur work is pretty good :)

Answer 38

oohhhh. i had the right numbers and process i just forgot to square it ! ...
Stupid mistake -_-... But it would be isoclese right ? because it has 2 equal sides ?

Answer 39

yes it is isosceles !!

Answer 40

Okkk Greaat. Your Great ! Thankss Againnn (:. i Got Another 100% Due to your help ! ... Thanks sooo much ! Welp Time for another assighnment !

Answer 41

you deserve 100% you're very good in math !! good luck for another 100% :)
