Answer:
C=252
Step-by-step explanation:
Given:
x^5y^5
(x+y)^10
Find the coefficient of x^5y^5
To get the coefficient of x^5y^5,
we will put r = 5, in the below given general term.
The general term is : nCr =x^ry^n-r
We get:
Coefficient is = 10C5
= 10!/5!*5!
= 252
The coefficient of x^5y^5 is 252
C. 252
Hello!
The midpoint formula is basically an average of x and y.
It is also written as: .
With the formula above, we can substitute the given points into the equation, and simplify.
Therefore, the midpoint between points H and J is choice D, (6, 3.5).
