r^2 + 15^2 + 15^2
r = sqrt (450)
tan O = 15/15 = 1
so O = 45 degrees
so polar form for 15 + 15i
= sqrt 450 ( cos 45 + i sin45) or
21.2 (cos 45 + i sin 45)
Answer:
12.207 or 12.21
Step-by-step explanation:
I found it on Brainly somewhere
The correct option is A.
One of the basic feature of an experiment is the selection of participants by means of random method. It is very important to select participants randomly in order to avoid experimental bias that may occur as a result of the participants not been an exact representation of the concerned population.
Hey there! :D
When you have a value, it is usually positive.
For example, if I have 5 chocolate bars, then I have +5 chocolate bars.
When you take away a value, it is usually negative.
For example, I have 3 chocolate bars away, then I would have 3 fewer chocolate bars. (-3)
Integers are negative or positive whole numbers.
12 songs= 12 <== the integer
Delete 5 old songs= -5 <=== the integer
I hope this helps!
