The first thing we must observe is the point V '.
The point V 'in this case is given by:
V '= (0, 1)
The dilatation rule is:
1/3 (x, y) → = (0, 1)
Therefore, we have the following system of equations:
1 / 3x = 0
1 / 3y = 1
Clearing we have:
x = 0
y = 3
FINAL ANSWER: (0,3)
Answer:
149.5
Step-by-step explanation:
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.
The slope is: y = 3x + 6
The y-intercept is: 6
