Concept explainers
(a)
To Graph: To graph the given log rules.
(a)
Explanation of Solution
Given information:Rate of interest in both funds and total interest earned.
Graph:
Interpretation:
In the above graph, x-axis represent the diameter of log in inches and y-axis represent the volume of the log. Scribner log rule shown in blue and Doyle log rule shown in green
(b)
To find: To find the diameter who satisfies the both rule
(b)
Answer to Problem 88E
When diameter is 24.71 or 3.86
Explanation of Solution
Given information:Given Scribner log rule and Doyle log rule
Formula used: Substitution method
Calculation:
Since the given rules are
Using, quadratic formula
Hence when diameter is 24.71 or 3.86 the rules are agreed.
(c)
To Explain: Toexplain the rule apply for selling the given logs.
(c)
Answer to Problem 88E
The answer is Scribner log rule.
Explanation of Solution
Given information:Given Scribner log rule and Doyle log rule with graph
The Scribner log rule gives more volume than the Doyle log rule which can be clearly seen in the graph.
Therefore, with maximum volume the profit is also maximum for selling logs under the Scribner log rule.
Hence the Scribner log rule is applied.
