Answer:
12.36%
Step-by-step explanation:
For year 1:
T(1) = 1000(1.06)¹
T(1) = 1060
After two years, t = 3
T(3) = 1000(1.06)³
T(3) = 1191.06
The percent of the increase is
[(T(3) - T(2)/T(2)]*100%
[(1191.06 - 1060)/1060]*100%
12.36%
A = 4πr² Divide both sides by 4π
A / 4π = r² Find the square root of both sides
√(A / 4π) = √(r²) Cancel out the square with the square root
√(A / 4π) = r Switch the sides to make it easier to read
r = √(A / 4π)
Perimeter
2l + 2w = 27
l + w = 13.5
Area
l*w = 35
(35 / l) + l = 13.5
35 + l^2 = 13.5l
l^2 - 13.5l + 35 = 0
Using this equation, we can find the length first
then width can be found
