The function is in polar coordinates.
When this is the case, to pass to rectagular (cartesian) coordinates you use:
x = r cos(theta)
y = r sin(theta)
Then,
x = [2cos(theta) + 2sin(theta)]cos(theta) =
= 2 [cos(theta)]^2 + 2sin(theta)cos(theta) = 2 [cos(theta)]^2 + sin(2theta)
y = [2cos(theta) + 2sin(theta)]sin(theta) =
= 2 cos(theta)sin(theta) + 2[sin(theta)]^2 = sin(2theta) + 2[sin(theta)]^2

Answer:
C) 0.45
Step-by-step explanation:
Given that a population mean is 0.45, standard deviation is 0.001 and margin of error stands at 0.5% we have the following
0.45 + 0.001 = 0.451
Population mean with standard deviation is 0.451.
0.451 * 0.5% = 0.448745
We now reduce the number to two decimals and get the final marigin of error
0.45 as result
