In two or more complete sentences, analyze how to find the third term in the expansion of (2x + y)4.

jarptica [38.1K]

The first term in the binomial is "x2", the second term in "3", and the power n is 6, so, counting from0 to 6, the Binomial Theorem gives me:(x2 + 3)6 = 6C0 (x2)6(3)0 + 6C1(x2)5(3)1 + 6C2 (x2)4(3)2 + 6C3 (x2)3(3)3+ 6C4 (x2)2(3)4 + 6C5 (x2)1(3)5 + 6C6 (x2)0(3)6Then simplifying gives me(1)(x12)(1) + (6)(x10)(3) + (15)(x8)(9) + (20)(x6)(27)+ (15)(x4)(81) + (6)(x2)(243) + (1)(1)(729)= x12 + 18x10 + 135x8 + 540x6 + 1215x4 + 1458x2 + 729

Find the balance in the account after the given period.

Lapatulllka [165]

Answer:

balance after 4 years = $4502

Step-by-step explanation:

Formula to get the final amount when compounded annually is,

Final amount = $\text{Principal amount}\times (1+\frac{r}{n})^{nt}$

Here, r = rate of interest

n = number of compounding per year

t = Duration of investment

From the given question,

Final amount = $4000(1+\frac{0.03}{1})^{(1\times 4)}$

= $4000(1.03)^4$

= 4502.0352

≈ $4502

Therefore, balance after 4 years = $4502

Part 1. Please show work. Please assist me with these math problems.

Vitek1552 [10]

Answer: 1) 2, 3, 4, 9, 32, 279, 8896, 2481705, 22077238784

2) 2,490,924

3) Neither

Step-by-step explanation:

$S_n=S_{n-2}\cdot (S_{n-1}-1)\quad \\\\S_1=2\quad given\\S_2=3\quad given\\S_3=S_1(S_2-1)\quad =2(3-1)\quad =4\\S_4=S_2(S_3-1)\quad =3(4-1)\quad =9\\S_5=S_3(S_4-1)\quad =4(9-1)\quad =32\\S_6=S_4(S_5-1)\quad =9(32-1)\quad =279\\S_7=S_5(S_6-1)\quad =32(279-1)\quad =8,896\\S_8=S_6(S_7-1)\quad =279(8896-1)\quad =2,481,705\\S_9=S_7(S_8-1)\quad =8896(2481705-1)\quad =22,077,238,784$

$\sum^8_{k=1}S_k\\\\=S_1+S_2+S_3+S_4+S_5+S_6+S_7+S_8\\\\= 2,490,924\\$

Neither

Not arithmetic because the difference between each of the terms is not the same.

S₂ - S₁ S₃ - S₂ S₄ - S₃

3 - 2 = 1 4 - 3 = 1 9 - 4 = 5

Not geometric because the ratios between each of the terms is not the same.

$\dfrac{S_2}{S_1}=\dfrac{S_3}{S_2}\qquad \rightarrow \dfrac{3}{2}=\dfrac{4}{3}\qquad \rightarrow \text{cross multiply to get}: 9\neq 8$
