WINSTONCH [101]


In general the binomial expansion is


(a+b)^n = {n \choose 0} a^0 b^n + {n \choose 1} a^1 b^{n-1} + {n \choose 2} a^2 b^{n-2} + ... + {n \choose n} a^n b^0


So in our case, because we want ascending powers of x we'll write,


(-3x + 1)^{11} =  {11 \choose 0} (-3x)^0 1^{11} + {11 \choose 1} (-3x)^{1} 1^{10} + {11 \choose 2} (-3x)^{2} 1^9  + {11 \choose 3 } (-3x)^3 1^8 + ...


We need to calculate the binomial coefficients:


{11 \choose 0}  = 1


{11 \choose 1}  = 11


{11 \choose 2}  = \dfrac{11 \times 10}{2} = 55


{11 \choose 3}  = \dfrac{11 \times 10 \times 9}{3 \times 2} = 165


(-3x+1)^{11} =  1 (-3x)^0 1^{11}  + 11(-3x)^{1} 1^{10}  + 55 (-3x)^2 1^{9}  + 165 (-3x)^3 1^8 + ...


(1-3x)^{11} =  1 -33 x + 495 3x^2 - 4455 x^3+ ...

1b. -4 3/5

2. 33

Step-by-step explanation:

1a. -4 4/5 + 1/5 = -4 3/5

1b. -4 2/5 + (-1/5) = -4 3/5

2. (-16 -35) + 18 = -33

You would need to draw the number 33 to get a score of 0.

Answer: 243, 729

<u>Step-by-step explanation:</u>

1, 3, 9, 27, 81    is a geometric sequence where r = 3

a₁ = 1

a₂ = 1 x 3 = 3

a₃ = 3 x 3 = 9

a₄ = 9 x 3 = 27

a₅ = 27 x 3 = 81

To find the next two terms, multiply the previous term by 3:

a₆ = 81 x 3 = 243

a₇ = 243 x 3 = 729
