I jumped from 10 to 12 for some strange reason
mckenzieandjesus
  • mckenzieandjesus
no 12
jim_thompson5910
  • jim_thompson5910
sorry I see where I added the extra number
jim_thompson5910
  • jim_thompson5910
ok yeah, 12
mckenzieandjesus
  • mckenzieandjesus
ok lol
jim_thompson5910
  • jim_thompson5910
anyways, divide 360 degrees by 12 360/12 = 30
jim_thompson5910
  • jim_thompson5910
going from person to person means that you go 30 degrees along the outer arc
jim_thompson5910
  • jim_thompson5910
so going from Abbey to Kai means we go 2 spots (2 spots)*(30 degrees per spot) = 60 degree rotation
mckenzieandjesus
  • mckenzieandjesus
yeah but the next spot i over 180? if its 30 degree each spot
jim_thompson5910
  • jim_thompson5910
going from Kai to Haifa means we move 3 spots (3 spots)*(30 degrees per spot) = 90 degree rotation
mckenzieandjesus
  • mckenzieandjesus
its 2 spots and the 5 spots?
mckenzieandjesus
  • mckenzieandjesus
ohh i see lol
jim_thompson5910
  • jim_thompson5910
yeah it's starting from Kai on the second part (and not Abbey)

A taxicab starts at (1, -2) on the grid and picks up a passenger. The taxicab travels a total of 16 blocks, and then drops the passenger off. Which composition of two translations could describe the taxicab’s final position? (x, y) > (x + 4, y - 3), and then (x, y) >(x - 9, y + 1). (x, y) > (x - 4, y + 3), and then (x, y) > (x + 6, y - 1). (x, y) > (x - 3, y + 4), and then (x, y) > (x + 8, y - 1). My answer (x, y) > (x - 3, y + 4), and then (x, y) > (x + 7, y - 1).

good, choice C is the only one where the total distance traveled is 16 blocks

In the diagram, triangle ECD is a _____ of triangle ABC across line p.
mckenzieandjesus
  • mckenzieandjesus
translation glide reflection rotation reflection (my guess)
jim_thompson5910
  • jim_thompson5910
let me think
mckenzieandjesus
  • mckenzieandjesus
ok
jim_thompson5910
  • jim_thompson5910
this is what I get when I reflect ABC over line p
1 Attachment
jim_thompson5910
  • jim_thompson5910
the reflection does not line up with ECD so reflection doesn't work I couldn't get glide reflection to work either
jim_thompson5910
  • jim_thompson5910
translation doesn't work either the only thing left is rotation. The only issue is that I'm not sure how they're rotating it. This problem is just odd
jim_thompson5910
  • jim_thompson5910
if line p were along BC, then a glide reflection would work but that's not the case since line p is through EC
mckenzieandjesus
  • mckenzieandjesus
hmm
jim_thompson5910

I think the authors messed up

A blueprint for a fence has a scale of 1:40. The fence in the blueprint is 6 in. What is the length of the actual fence? 20 feet 240 feet (or this one) 20 inches (my answer) 72 feet
mckenzieandjesus
  • mckenzieandjesus
@jim_thompson5910
jim_thompson5910
  • jim_thompson5910
"has a scale of 1:40" means that you multiply the smaller dimension (6 inches) by 40 to get the corresponding longer dimension then convert to feet
mckenzieandjesus
  • mckenzieandjesus
Yeah. 6*40=240 240/12 = 20 right?
jim_thompson5910

looks good
