Answer:
Three Times.
Step-by-step explanation:
First and foremost a binary search requires that the array be sorted in ascending or descending order.
After the initial step the search goes to the middle most value
i.e.
will be the second 14, which is the first iteration.
Since 14 is less than 19 the search will eliminate the lower half of the including 14, and will iterate again through the array:
The array will go to the middle most value which is 18, second iteration. Since 18 is less than 19, the program will eliminate the lower half and be left with two values i.e. .
The search will run once i.e. third iteration, and will return key value found.
Answer:
The lengths of the sides are 20 cm and 20 cm
Step-by-step explanation:
Given
Perimeter, P = 80cm
Represent the length and width with L and W, respectively;
Substitute 80 for P
Divide through by 2
Make L the subject of formula
Area of a rectangle is calculated as thus;
Substitute 40 - B for L
Express this as a function
Set A(B) = 0 to determine the roots
Hence;

The maximum area of a rectangle occurs at half the sum of the roots;
So;
Recall that
<em>Hence the lengths of the sides are 20 cm and 20 cm</em>
