Answer:
The correct option is;
False
Step-by-step explanation:
The coefficient of x^k·y^(n-k) is nk, False
The kth coefficient of the binomial expansion, (x + y)ⁿ is 
Where;
k = r - 1
r = The term in the series
For an example the expansion of (x + y)⁵, we have;
(x + y)⁵ = x⁵ + 5·x⁴·y + 10·x³·y² + 10·x²·y³ + 5·x·y⁴ + y⁵
The third term, (k = 3) coefficient is 10 while n×k = 3×5 = 15
Therefore, the coefficient of x^k·y^(n-k) for the expansion (x + y)ⁿ = 
not nk
87.41898806% or 87% is what i got
The diameter is 10 so it would be pi•radius squared 3.14•52sq or 3.14•10•2=78.54 the base of the circle is 78.54
Answer:
it should be x=4
Step-by-step explanation:
The line that is perpendicular to
y
=
−
3
is a horizontal line, because horizontal and vertical lines (
x
- and
y
- axes for example) are perpendicular. Therefore, this line will take the form
x
=
n
where
n
is the
x
-coordinate of the point passed through. The
x
-coordinate of the given ordered pair
(
4
,
−
6
)
is
4
, so the equation must be
x
=
4
Y = 15x but I'm not sure :/
