First case:
average of test score =70
number of students =p
total score of 'p' students = ( average of test score)*( number of students)
total score of 'p' students =70p
Second case:
average of test score =92
number of students =n
total score of 'n' students = ( average of test score)*( number of students)
total score of 'n' students =92n
total number of students = p+n
total average score =86
so, total score =86(p+n)
total score = total score of 'p' students +total score of 'n' students

now, we can simplify it



now, we can find p/n

The power series for given function
is
For given question,
We have been given a function g(x) = 4x / (x² + 2x - 3)
We need to find a power series for the function, centered at c, for c = 0.
First we factorize the denominator of function g(x), we have:

We can write g(x) as,

We know that,
if |x| < 1
and
if 
if |x| < 1 and if 
if |x| < 1
Therefore, the power series for given function
is

Answer:
x^2 + 6
Step-by-step explanation:
X squared or "x^2" just means X times X. For example, 9^2=81 which is the same as 9x9. Then just add 6.
Hope this helps
