Answer:
The equal number of books that is arranged on 16 empty shelves is 36 .
Step-by-step explanation:
Given as :
The total number of books Miguel need to arrange = 576
The total number of empty shelves = 16
Let The total number of books arrange on each shelves = x
So , According to question
The total number of books Miguel need to arrange = The total number of empty shelves × The total number of books arrange on each shelves
I.e 576 = 16 × x
Or, x = 
∴ x = 36
Hence The equal number of books that is arranged on 16 empty shelves is 36 . Answer
Answer:
2 cis (7/6 pi)
Step-by-step explanation:
r = sqrt( a^2 + b^2)
r = sqrt (-sqrt(3) )^2 + (-1)^2)
= sqrt(3 +1)
= sqrt(4)
= 2
theta = arctan (b/a)
theta = arctan (-1/-sqrt(3))
theta = 30
but this is in the third quardrant -a and -b
so add 180
theta = 210 degrees
convert this to radians
210 * pi/180 = 210/180 * pi = 21/18 * pi = 7/6 * pi
r cis (theta)
2 cis (7/6 pi)
Remark
Many calculators have a key that will do this in one step. Mine is one of them. So let's start with the answer and then we'll do it the long way.
9C3 = 84. You put it into your calculator as 9 2nF nCr 3 =
Solution
3*4*7 = 84 which is what you set out to show.
