The worst-case update cost in a tree-based replication with n locations registers is O(log n).
In tree-based replication, updates are propagated from the root to the leaf nodes in a hierarchical manner. The update cost is determined by the number of nodes that need to be updated to propagate the change to all locations. In the worst case, the update needs to be propagated from the root to all the leaf nodes. This results in a total of log n levels in the tree, where n is the number of locations registers. At each level, the update needs to be propagated to all the nodes at that level. Therefore, the worst-case update cost is O(log n).
In tree-based replication, the system is organized as a tree, with the root node representing the master copy of the data and the leaf nodes representing the replica copies. Each internal node in the tree maintains a copy of the data and forwards updates to its children nodes. This way, updates propagate down the tree in a hierarchical manner until all leaf nodes have received the update. The update cost in tree-based replication depends on the depth of the tree and the number of nodes at each level. In the worst case, when all locations registers need to be updated, the update needs to be propagated from the root to all the leaf nodes. Assuming that the tree is balanced, the number of nodes at each level is approximately equal to 2^k, where k is the level of the node. Therefore, the total number of nodes in the tree is 2^0 + 2^1 + 2^2 + ... + 2^(log n - 1) + 2^(log n) = 2^(log n + 1) - 1. This is equivalent to 2n - 1, where n is the number of locations registers.

Shareholders had a good year, earning a 29% annual rate of return. The PE ratio today is 10.0 and the company just announced earnings per share of $2.50. The company has a 90% payout ratio. How much did the stock price change over the past year?
Answer:
$3.68
Explanation:
Rate of return =29%
PE ratio = 10.0
Earning per share = $2.50
P1 = PE ratio * EPS
P1= 10*2.50
P1 = $25
Payout ratio = 90%
Dividend = 2.50*90%
Dividend = $2.25
Rate of return = (P1+D1-P0)/P0
0.29= (25 + 2.25 - P0)/P0
0.29 P0 = 27.50 - P0
1.29P0 = 27.50
P0 = 27.50/1.29
P0 = $21.32
Change in stock price = $25 - $21.32
Change in stock price = $3.68
