In binary tree there are
n ancestor at level n.
Proof :
Take P(0): At node level
0, it has no ancestors since this is a roo tnode.
Take P(1): At node level
1, it has one ancestor. The ancestor is the root, its parents which is at level
0.
Take P(K): A node level
K it has K ancestors. Its parent is at level K – 1.
Take P(K+1): At node K +
1 level have more than one ancestor than that of node at k level.
<span>Thus there are n ancestor
at level n in binary tree.</span>
Answer:i hope this helps
look at last line
Step-by-step explanation:Objective function is to maximize income.
The linear equation of the objective function is max (x1 + x2); where x1 = # of haircuts and x2 = # of haircut & color.
Constraints:
#1) 0.5*x1 + 2* x2 < =10.
0.5* x1 represents 0.5 hrs. per haircut and 2*x2 represents 2 hrs. per haircut & color.
The expression < = 10 represents that there are no more than 10 hour per day which Natalie will work.
#2) x1 + x2 < = 8
This expression represents the fact that Natalie doesn’t want more than 8 clients per day.
Recall x1 represents # of haircuts and x2 represents # of haircut & color, so x1 + x2 <=8 should make sense.
Answer:
The length is 24, width is 6
Step-by-step explanation:
Since we know the length and width cannot both be 12 (to make 144), other factors of 12 can be tested to be a product of 144. Half of 12 is 6, and 24 * 6 = 144. If we add up 12 + 12 + 6 + 6, we get 60, or the given perimeter.

I think it is equalivilent to the number 607
Because d is the letter for 500
and c is 100
V is 5
and I is 1
so in total is 607
