I'd start with setting up the equations. Calling x the number of students in most popular country 1, and y in country 2.
x + y = 44740
x - y = 5672
now solve for x1 and x2. You can subtract second from first:
0 + 2y = 39068
y = 19534
so
x = 5672 + 19534 = 25206

Answer:
The principal square root of -4 is 2i.
Step-by-step explanation:
= 2i
We have the following steps to get the answer:
Applying radical rule 
We get 
As per imaginary rule we know that 
= 
Now 
Hence, the answer is 2i.
Answer:
A. horizontal reflection
Step-by-step explanation:
Given:


To identify the type of transformation.
Solution:
On close observation of the functions we find the that sign of
has changed in
with other terms being constant.
<em>Thus, the transformation statement can be given as:</em>

As:


The transformation
describes horizontal reflection of function across the y-axis.
Thus,
is horizontally reflected across y-axis to get
.
