Answer:
C
Step-by-step explanation:
The common ratio can be < 0 
All that means is the entry's signs alternate.
For example
r = - 2
a = 3
Series = 3    -6    18     -54 etc. The members of the series become larger and larger in magnitude and the series diverges. It is not clear where it might stop.
-1 < r < 0 gives a much better behaved result.
The point is that c is incorrect.

Answer:
Part 1: 43.75% 
Part 2: 44.07%
Step-by-step explanation: 
Hello!
(Pt.1) First, set up a ratio  . Next, you use long division I got the percent 43.75. After that, you subtract 6 from the girls group, (because of them moving away and then more coming back.) and 2 from the boys group. Then, you subtract those from the school "population" and you get 472 as the final population. So then you set up another ratio,

Answer: a) -6, b) 32, c) -48, d) 9, e) -12
Step-by-step explanation:
Since we have given that 
A and B are 4 × 4 matrices.
Here, 
det (A) = -3
det (B) = 2
We need to find the respective parts:
a) det (AB)

b) det (B⁵ )

c) det (2A)
Since we know that 

so, it becomes,

d) 
Since we know that 

so, it becomes,

e) det (B⁻¹AB)
As we know that 

so, it becomes,

Hence, a) -6, b) 32, c) -48, d) 9, e) -12
