Answer:
y=(1/2x)sqrt 2
Step-by-step explanation:
On edge
1. 6 people
2. 52 people
3. 13 people said it takes less than half hour, and 13 people said it takes longer than half hour. It’s a tie.
4. When asked, it takes most people either 30 minutes or 60 minutes.
Answer:
QT < TR.
Step-by-step explanation:
QT = TR because TZ is a mid segment so QT < TR is false.
No map given but it shouldn't matter.
E is the 5th letter, L the 12th.
Start at S(6,12). End at E(10,5)
The vector between them, E-S=(4,-7)
Each unit is 1/16 of a mile, though that probably doesn't matter that much.
Doug has to stay on the grid, so has to run |4|+|7|=11 units. At 30 mi/hr that takes (11/16)/30 = 0.022916 hours.
Bert can go diagonally, so flies √(4²+7²)=√65 ≈ 8.06 units. At 20 mi/hr that takes (8.06/16)/20 = 0.025194 hours.
Answer: Doug wins
Why? Because it's quicker to cover 4+7 at 30 mph than it is to cover √(4²+7²) at 20 mph. That is, Doug is 1.5 times faster and the 1.5 times the diagonal distance is more than the grid distance.
