39=3m-15
39+15=3m
54=3m
54/3=3m/3
m=18
a quarter of a circle is 19.625
so the area of full circle is 19.625 x 4 = 78.5 sq. km
area of a circle is PI x r^2
78.5 = 3.14 x r^2
78.5/3.14 = 25 = r^2
r = sqrt(25) = 5
radius is 5 km
circumference ( perimeter) = 2 x PI x r
2 x 3.14 x 5 = 31.4 km
perimeter is 31.4 km
A=P(1+rt)
A=500(1+6.6%)^2
A=$568.18
Answer is D
A is the answer to your question
Answer:
The ancient puzzle was created by Indian mathematicians over 2000 years ago. The puzzle can be solved using a simple technique: If loga^b = c, then b^c = a
Step-by-step explanation:
for y = 3^x
To find the inverse, replace y by x and vice-versa, then solve for y
x = 3^y
Take log to base 3 of both sides
log3^x = log3^(3^y)
y = Log 3^x
The inverse of the function y = 3^x given as y = log 3^x completely depicts the idea of the ancient puzzle.
