Question

I NEED SOME HELP PLEASE
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?


36 meters
40 meters
54 meters
60 meters
68 meters

Answer 1

Where is the graph image? @asela121

Answer 2

thank you but i answered the question already my teacher helped me... do you think you can help me with another problem?

Answer 3

@bajji

Answer 4

ya... if i can... :)

Answer 5

okay thank you

Answer 6

If A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4) form two line segments, AB and CD , which condition needs to be met to prove AB and CD?
the image can help

Answer 7

It says the condition is AB perpendicular CD so, the (Slope of AB)*(Slope of CD)=-1
If the slope AB is m, then the slope of a CD(say, m2) would be -1/m

this means that m2 = -1/m and so m2 x m = -1
Now can you find which is the right option? :) @asela121

Answer 8

yes :) so it would be the third one right ? @bajji

Answer 9

Exactly! :)

Answer 10

thank you :D
