Question

please help

Answer 1

You need to find the length. So you can read the length on the graph for, Amber to Betsey, and from Betsey to Claire. What is the length?

Answer 2

a - b= 8 units
b - c= 7 units

Answer 3

after this got time for another?

Answer 4

Yea, so now you need to find the length from a to c. This is done by Pythagoras again. \[a^2+b^2=c^2\]

Answer 5

c is the hypotenuses, while a and b is the legs

Answer 6

Do you know how to find the length c now?

Answer 7

\[a^2+b^2=c^2 <=> c=\sqrt{a^2+b^2}\]

Answer 8

ok here is the other 2

Answer 9

What answer did you get? How many blocks does Amber walk?

Answer 10

10.63

Answer 11

thats squqre root

Answer 12

square

Answer 13

113 is before square root

Answer 14

Yes so you get \[c=10.63\] Now the answer is \[10.63+7=17.63\] Because she walks from A to C and from C to B :)

Answer 15

Now in question 4. Here you have 2 legs again, so you should be able to calculate the hypotenuses right? - You just use the Pythagorean theorem

Answer 16

oh i see thanks

Answer 17

i got 250 do i square root them?

Answer 18

or is that my answer

Answer 19

\[c=sqrt(5^2+15^2)\]

Answer 20

ok

Answer 21

So it is either \[c=sqrt(250)\] or if you want to find it in decimal it is around 15.8 or so. But you have an answer \[sqrt(250)\] So that would be it :)

Answer 22

For the last question 5: "In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a relation in Euclidean geometry among the three sides of a right triangle." - Source: Wikipedia.

So the key word here is "right triangle". You can ONLY use this Pythagorean theorem on a RIGHT triangle. So what triangle is right? If you look at the pictures?

Answer 23

b?
also i have to more and thats it do you have time

Answer 24

That is correct

Answer 25

Sure, I got a little bit of time

Answer 26

there they are ive never head of what the triples are

Answer 27

waity the 4.png is wrong

Answer 28

this is the right one

Answer 29

So lets look at question 5. You need to use the theorem again, but this time you have to "make your own" RIGHT triangle.

Answer 30

ok so its 6.40 ?

Answer 31

Correct

Answer 32

So about the last question, you have these Pythagorean tripes. They are special. Lets look at 3,4,5. You have 2 legs 3,4 and the hypotenuse 5. \[a^2+b^2=c^2 <=> c=sqrt(a^2+b^2)\] Now with this triangle you get: \[c=sqrt(3^2+4^2)=sqrt(25)=5\]

Answer 33

They give this nice and whole positive number, as their hypotenuses.

Answer 34

ok so is the last one 17
the 8 ,15 ,17

Answer 35

I have to admit, I dont know exactly what the question wants you to do. But The smallest Pythagorean Triple is 3, 4 and 5. And yes 8,15,17 is also a pythagorean triple. \[c=sqrt(8^2+15^2)=sqrt(289)=17\]
