Arc tan ( 1/√3 ) = arc tan ( √3/3 ) = 30°
180° = π ( in radians )
30° = 180°/6 = π/6
Answer:
The answer is -1.8
Step-by-step explanation:
5 x -1.8 = -9 = -9 divided by -1.8 = 5
The standard equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
where the center is at point (h,k)
From the statement of the problem, it is already established that h = 2 and k = -5. What we have to determine is the value of r. This could be calculated by calculating the distance between the center and point (-2,10). The formula would be
r = square root [(x1-x2)^2 + (y1-y2)^2)]
r = square root [(2--2)^2 + (-5-10)^2)]
r = square root (241)
r^2 = 241
Thus, the equation of the circle is

Answer:
Step-by-step explanation:
1)Population of Interest : All UC Berkeley Undergraduates
Sample : 129 UC Berkeley Undergraduates
2)
Can the results of the study be generalized to the population of interest?
No, because the sample is not representative of the population since it consists of only UC Berkeley undergraduates.
3)
No, because the the study is observational.
