A regular octagon has all its eight sides congruent. The line segments joining each of the vertices of a regular octagon to its center are called the radii of the octagon. These 8 radii divide a regular octagon into 8 congruent isosceles triangles. Area of each isosceles triangle is
,
where a is length of the side of the octagon and 
is the angle between two radii of the octagon.
In regular octagon
.
Then the area of regular octagon is
sq. m.
Answer: 
sq. m.

In the case of bacteria, we use the continuous growth equation:
Final=Initial×e∧(r×t)
In other words, the final amount is equal to the initial amount times e to the rate times time. In order to find your rate, you would plug in the numbers as follows:
3600=3000×e∧(6r)
Therefore: r=0.03
Next, you would plug in the r value and 13 hours into the equation to solve for the final amount.
F=3000×e∧(13×0.03)=4,453 bactera after 13 hours
Answer:
Answer B: 2
Step-by-step explanation:
You can multiply the numbers of the smaller triangle and determine the answer
The answer would be negative 2.
-9+6=-3
List the numbers -3,-2,-1
The number in the middle is -2 and that is our answer.
