L S = sin x/( 1 + cos x) * ( 1 - cos x ) / ( 1 - cos x ) =
= sin x ( 1 - cos x ) / ( 1 - cos² x ) =
= ( sin x - sin x cos x ) / sin² x =
= sin x / sin² x - ( sin x cos x ) / sin² x =
= 1 / sin x - cos x / sin x = csc x - cot x = RS
Therefore: LS = RS
C.
Although this is not the exact answer the circumference formula is 2(pi)r. Which is far more than the other two options.

<h3>Answer: 1981</h3>
===================================
Work Shown:
Recall that P is in thousands, so P = 95 means 95,000.
Plug in P(x) = 95. Solve for x. Use logarithms to get this done.
P(x)=230(0.881)^x
95=230(0.881)^x
95/230 = (0.881)^x
0.41304347826087 = (0.881)^x
(0.881)^x = 0.41304347826087
Log( (0.881)^x )= Log( 0.41304347826087 )
x*Log( 0.881 )= Log( 0.41304347826087 )
x= Log( 0.41304347826087 )/Log( 0.881 )
x= 6.97883817154785
x= 7
Approximately 7 years after 1974 is when the population will be around 95,000.
7 years after 1974 = 1974+7 = 1981
The rectangle i would say is a parallelogram. Since a parallelogram has sides that are parallel which explains the name: parallelogram :) :D
