Answer:
Step-by-step explanation:
You'll have an idea of the positive or negative charge on the ion from the periodic table
For example Magnesium is in group 2 and its ionic charge is +2 Mg2+
In the higher groups the charge on the on is negative For example
Chlorine ion is Cl- (its in group 7 and it has (8-7) = 1 negative charge
Answer:
- A"(-1, -2)
- B"(6, 0)
- C"(3, 3)
- (x, y) ⇒ (x+1, y+1)
Step-by-step explanation:
Translation vectors add, and the addition is commutative and associative.
__
The first translation adds (-1, 2) to the original coordinates. The second translation adds (2, -1) to the original coordinates. The two translations together add ...
(-1, 2) +(2, -1) = (-1+2, 2-1) = (1, 1)
to the original coordinates.
The single rule representing this translation is ...
(x, y) ⇒ (x +1, y +1)
Then the doubly-translated coordinates are ...
A(-2, -3) ⇒ A"(-1, -2)
B(5, -1) ⇒ B"(6, 0)
C(2, 2) ⇒ C"(3, 3)
I think the answer is B but I'm not sure
The probability of spending more than 1 minute for this download is : Very Low or almost impossible.
Even after counting the standard deviation, the worst amount of time is about 45 seconds
hope this helps
