Answer:
Step-by-step explanation:
Given that:
all coins are same;
The same implies that the number of the non-negative integral solution of the equation:
Thus, the number of the non-negative integral solution is:
(b)
Here all coins are distinct.
So; the number of distribution appears to be an equal number of ways in arranging 35 different objects as well as 5 - 1 - 4 identical objects
i.e.
(c)
Here; provided that the coins are the same and each grandchild gets the same.
Then;
Thus, each child will get 7 coins
(d)
Here; we need to divide the 35 coins into 5 groups, this process will be followed by distributing the coin.
The number of ways to group them into 5 groups =
Now, distributing them, we have:
Answer:
(B)A': (p, m) and B': (z, −w)
Step-by-step explanation:
Line AB has a negative slope and goes through points (-m, p) and (w, z).
Line A'B' has a positive slope and intersects with line AB.
Definition: Two lines are perpendicular if the product of their slopes is -1.
Slope of AB
From the options, we consider the coordinates whole slope multiplied by the slope of AB gives a result of -1.
In Option B: A': (p, m) and B': (z, −w)
Slope of A'B'
The product of the slopes
Therefore, the coordinate for points A' and B' which would help prove that lines AB and A'B' are perpendicular is A': (p, m) and B': (z, −w).
You can try to calculate the slope of the others. They would not satisfy this condition.
