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)
Answer:
The girls' basketball team is playing against the boys' basketball team. The coach chooses a captain for the girls' team and then chooses a captain for the boys' team.
Step-by-step explanation:
Two events are considered independent of each other when the probability that one event occurs doesn’t in any way affect the probability of the other event occurring.
An example is the probability of flipping a coin and rolling a die.
Choosing a captain for the male and female team won’t in any way affect the outcome of the match.

Answer: 22
Step-by-step explanation:
Answer:
t=25
Step-by-step explanation:
multiply both sides by -5
where you get t=-5(-5)
where you get t=25
