<u>Given</u>:
Given that the regular decagon has sides that are 8 cm long.
We need to determine the area of the regular decagon.
<u>Area of the regular decagon:</u>
The area of the regular decagon can be determined using the formula,
where s is the length of the side and n is the number of sides.
Substituting s = 8 and n = 10, we get;
Simplifying, we get;
Rounding off to the nearest whole number, we get;
Thus, the area of the regular decagon is 642 cm²
Hence, Option B is the correct answer.
The expression for the total amount that Lupita paid for the gown would be 1.06g.
The amount of the tax is 0.06g and the cost of the g is just 1g. If we add the two expressions together will will get the total amount paid.
0.06g + 1g = 1.06g
Answer:
k = 1.2
Step-by-step explanation:
Solving for t when the account value is 30,000, we have ...
30,000 = 25,000e^(0.0198t)
30,000/25,000 = 1.2 = e^(0.0198t)
ln(1.2) = 0.0198t
t = ln(1.2)/0.0198
Matching this with the form ...
t = ln(k)/0.0198
we see that k = 1.2.
_____
k is the multiplier of account value in time period t.
Coplanar lines are line witch lie on the same lie on the same plane. two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. lines in three dimensional space are coplanar, only if they are not skewed lines.
