Answer:
yes it does represent a function.
Step-by-step explanation:
The rectangular form of the equation is
(x+2)^2 + (y+1)^2 = 5
r = sqrt(5)
then the answer is <span>D. √5 π</span>
Start from the positive x-axis and move counterclockwise about the origin. You will first pass through Quadrant I, then Q II, then Q III, and so on. Convince yourself that the angle pi/3 is in Q I; 2 pi/3 is in Q II; 5 pi/3 is in Q IV. Because 5 pi/3 is in Q IV, its adjacent side is positive and its opposite side is negative.
adj +1 1 sqrt(3) 1 sqrt(3)
cot 5pi/3 = --------- = ------------- = - ----------- = ------------- * ----------- = ------------
opp -sqrt(3) sqrt(3) sqrt(3) sqrt(3) 3
Note: If this is not completely clear to you, look up "special triangles" and look for a picture showing the hypotenuse, the adjacent side and the opposite side of the central angle. This is a "30-60-90 degree triangle" which has sides 1 and sqrt(3) and hypotenuse 2.
Answer:
Simple interest=$225 Total=$975
Step-by-step explanation:
6%of 750=
(750x6)/100= 45
45x5=225
750+225=975
