Answer:
<u>The correct answer is that the area of the regular octagon is 309 cm²</u>
Step-by-step explanation:
There are several formulas for calculating the area of a regular octagon. We will use this one for solving this question because it does not require additional information .
Area = (2 * s²)/tan 22,5°
s = 8 cm
Replacing with the real values, we have:
Area = (2 * 8²)/tan 22,5°
Area = 2 * 64/0.4142
Area = 128/0.4142
<u>Area = 309 cm² (Rounding to the nearest tenth)</u>
Given
![f(x)=\frac{1}{5x-6}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B1%7D%7B5x-6%7D)
To find the derivative of the give function,we apply below exponent rule first:
![\frac{1}{a}=a^{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Ba%7D%3Da%5E%7B-1%7D)
So,
Next, we apply the chain rule:
So,
We substitute back u=(5x-6):
Simplify:
Therefore, the answer is:
Answer:
Yes
Step-by-step explanation:
Yes, because there are two pairs of sides marked as congruent, seen by the line bisectors. And, angles T and S are marked as congruent.
Alright, so we have the difference = 4500-2800=1700. To find the percent increase, we do 1700/2800=around 0.61 = around 61% percent
