2x2 − 12x + 21. Axis of symmetry. 2.
Answer:
-243 gallons of water from the pool
Answer:
18
Step-by-step explanation:
6 divided by 2 = 3 + 8 = 11
11 x 2 = 22 - 4 = 18
Hope this helps! :>
To find the other side subtract the side given (6) squared from the hypotenuse (16) squared.
16^2 - 6^2 = 220^2
Square root of 220 = 14.8
Answer should be option 1: 15
Explanation:
We can demostrate this claim by using global induction.
First, if the board has only one row, then you eat the non poissoned block and you win.
If it is a 2x2 row, then you have to eat the bottom right block, and in his next move, your opponent will be forced to eat only one block, leaving only 2 on the table. Then you eat the non poissoned one and you win.
Lets suppose that you have a winning strategy for a 2xk board, for k < n. If the board has dimensions 2xn, then
- You eat the bottom right corner block
- If your opponent eats exactly the block next to it, then you apply the winning strategy and its done.
- If your opponent eats a right-side block, then you can always eat the left-side block immediately below to it, leaving the board in a similar state than after your first move. Then you keep applying the same strategy until your opponent cant eat right side blocks.
- If your opponent instead eats a left side block, then the board will turn into a 2xj board and you can use a winning strategy (which exists due to the inductive hypothesis).
This way, you will always have a winning strategy by being first.
