Answer:
-sqrt(3) -i = 2 cis (7pi/6)
Step-by-step explanation:
-sqrt(3) -i
We can find the radius
r = sqrt( (-sqrt(3)) ^2 + (-1) ^2)
= sqrt( 3 + 1)
= sqrt(4)
= 2
theta = arctan (y/x)
arctan (-1/-sqrt(3))
arctan (1/sqrt(3))
theta = pi/6
But this is in the first quadrant, and we need it in the third quadrant
Add pi to move it to the third quadrant
theta = pi/6 + 6pi/6
=7pi/6
-sqrt(3) -i = 2 cis (7pi/6)
It would be 1531600
How I did it
First I divided the percentage by 100. Example >> 0.6/100= 0.006
Then I took 2002 population >> 1522475 + 0.006 x 1522475 = 1531609.85

2:4 or 1/2.Step-by-step explanation:
Answer:
f(- 2) = 8
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 2
- 4(- 2)³ - 11(- 2)² +3(- 2) - 6
= 2(16) - 4(- 8) - 11(4) - 6 - 6
= 32 + 32 - 44 - 12
= 64 - 56
= 8
