Question

Fan + Medal

Answer 1

A group of college students built a self-guided rover and tested it on a plane surface. They programmed the vehicle to move along the path A–B–C–D–A represented on the coordinate plane. What distance will the rover cover if it completes one circuit?

Answer 2

Can you explain how

Answer 3

I can't give you a medal unless you do

Answer 4

please you have to add
meausre(AB)+measure(BC)+measure(CD)+measure(DA)=...

Answer 5

Michele can we do it step my step like you did with my other problems

Answer 6

ok! It's very simple, because measure(AB)=2;
measure(CD)16-2=14,
measure(DA)=11-2=9
as I can read from your graph. Now in order to calculate
measure(BC), you have to apply Pitagora Theorem

Answer 7

a2 + b2 = c2?

Answer 8

that' right!

Answer 9

hint:
measure(BC)=
\[\sqrt{(11-2)^{2}+(16-4)^{2}}=...\]

Answer 10

please complete!

Answer 11

64 + 144 = 208

Answer 12

@Michele_Laino

Answer 13

no, sorry 81+144=225, so measure(BC)=15

Answer 14

What did I do wrong

Answer 15

and your circuit is 2+14+9+15=40 meters long

Answer 16

Thank you!

Answer 17

Thank you!

Answer 18

please I think you did wrong difference (11-9)

Answer 19

oops sorry
difference (11-2)
