Question

I have 3 math questions i need help with please help me

Answer 1

5. If A(5, 5), B(3, 3), C(6, 8), and D(-3, 4), what is the length of AB? Round to the nearest tenth. (Points : 1)


Question 6. 6. If A(5, 5), B(3, 3), C(6, 8), and D(-3, 4), what is the length of BC? Round to the nearest tenth. (Points : 1)


Question 7. 7. If A(5, 5), B(3, 3), C(6, 8), and D(-3, 4), what is the length of CD? Round to the nearest tenth. (Points : 1)

Answer 2

@pooja195

Answer 3

do you got to ca

Answer 4

Distance formula is \[d=\sqrt{(x _{2}-x _{1})^2+(y_{2}-y_{1})^2}\]

Answer 5

Just take the x's and y's of the two points and plug them in to find the distance between them :)

Answer 6

i really don't understand how to do this ive been on this question for the pass hour and i cant get it wrong

Answer 7

Just plug the values into the formula I provided. The equation with the larger x will be the x2 and y2 equation.

Answer 8

Would you like me to walk you through the first one?

Answer 9

Please

Answer 10

So we're trying to find the distance between A and B. A is (5,5) and B is (3,3). Since 5 is greater than 3, A is going to be our x2, y2 equation and B is our x1, x2 equation. Now we just plug them into the formula. \[d=\sqrt{(5-3)^2+(5-3)^2}\] Solve the parentheses \[d=\sqrt{(2)^2+(2)^2}\] Find the square of it\[d=\sqrt{4+4}\]Add\[d=\sqrt{8}\] Since we're rounding to the nearest hundredth, that means that we're just gonna plug this into a calculator to find the result.

Answer 11

the first one is 6 right?

Answer 12

I just did the first one.

Answer 13

I did #5, as that is the first one on the list

Answer 14

oh okay lol i think i can do the last two or at least try

Answer 15

How about this? You set up the second one and if I need to, I'll correct you and help you through #6. After that, you do #7 on your own

Answer 16

okay i'll try

Answer 17

I don't know what to do after the first part i got 20. I don't think its right im sorry im like really bad at math

Answer 18

What did your initial setup look like?

Answer 19

I mean what did you fill in for \[d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\]

Answer 20

yeah with 5 and 8

Answer 21

and i got 20

Answer 22

Did it look something like this?\[d=\sqrt{(6-3)^2+(8-3)^2 }\]

Answer 23

yeah but not those numbers

Answer 24

Why not those numbers? We're doing #6 are we not?

Answer 25

28?

Answer 26

28? What about 28?

Answer 27

The answer to the first step?

Answer 28

\[d=\sqrt{(3)^2+(5)^2}\]

Answer 29

I got 28 again

Answer 30

\[d=\sqrt{(3*3)+(5*5)}\]

Answer 31

28 is it 28?

Answer 32

How in the world are you getting 28? And are you not paying attention to my posts? I'm helping you through it. I am seriously confused as to how you're getting 28

Answer 33

I dont know im using my calculator but i don't understand this thanks for helping though i appreciate it

Answer 34

Right now we have this\[d=\sqrt{(3*3)+(5*5)}\] Can you solve the parentheses?
