Answer:

-126

Step-by-step explanation:

For the binomial expression  (a-b)^{n} the coefficient of (r+1)^{th} term is given by {n \choose r} \times -1^{(r)}.

We have to find the coefficient of 6th term in the binomial expansion of

(x^{3}-y^{4})^{9}.

Hence n=9 and r=5

The coefficient of 6th term = {9 \choose 5} \times (-1)^{5}

                                             = -{9 \choose 5}

                                             = -126

The diameter of the base of the cone measures 8 units. The height measures 6 units. What is the volume of the cone?
Maslowich
V = \pir^2h/3

V = 3.14 x 4^2 x 6/3       (remember r is 1/2 of the diameter)
V = 3.14 x 16 x 2
V = 100.5

The general form of the equation of a circle is x^2+y^2−4x−8y−5=0.
lakkis [162]
X² - 4x    + y² - 8y    = 5

Complete the square:
x² - 4x + (4) +  y² - 8y + (16)    = 5 + (4) + (16)
→  (x - 2)²    +  (y - 4)²    = 25

Center: (2,4)
radius: √25 = 5
