Find 10 partial sums of the series. (round your answers to five decimal places.) ∞ 15 (−4)n n = 1

nikklg [1K]

Given

$\Sigma_{n=1}^\infty15(-4)^n$

The first 10 partial sums are as follows:

$S_1=\Sigma_{n=1}^{1}15(-4)^n=15(-4)=\bold{-60} \\ \\ S_2=\Sigma_{n=1}^{2}15(-4)^n=\Sigma_{n=1}^{1}15(-4)^n+15(-4)^2 \\ =-60+15(16)=-60+240=\bold{180} \\ \\ S_3=\Sigma_{n=1}^{3}15(-4)^n=\Sigma_{n=1}^{2}15(-4)^n+15(-4)^3 \\ =180+15(-64)=180-960=\bold{-780} \\ \\ S_4=\Sigma_{n=1}^{4}15(-4)^n=\Sigma_{n=1}^{3}15(-4)^n+15(-4)^4 \\ =-780+15(256)=-780+3,840=\bold{3,060} \\ \\ S_5=\Sigma_{n=1}^{5}15(-4)^n=\Sigma_{n=1}^{4}15(-4)^n+15(-4)^5 \\ =3,060+15(-1,024)=3,060-15,360=\bold{-12,300}$

$S_6=\Sigma_{n=1}^{6}15(-4)^n=\Sigma_{n=1}^{5}15(-4)^n+15(-4)^6 \\ =-12,300+15(4,096)=-12,300+61,440=\bold{49,140}$

The rest of the partial sums can be obtained in similar way.

Hey!

noname [10]

Answer:

A. Cylinder + cone

Volume is the sum of volumes:

V = Vcon + Vcyl = 1/3πr²h₁ + πr²h₂
V = 1/3π*9²*12 + π*9²*120 = 31554.2 cm³

Surface area of cone:

A = A=πr(r+√(h₁²+r²)) = π*9(9 + √(9²+12²)) = 678.6 cm²

Surface area of cylinder minus bases:

A = 2πrh₂ = 2π*9*120 = 6785.8 cm²

Total surface area:

678.6 + 6785.8 = 7464.4 cm²

-------------------------------------------------

B. Cube+ pyramid

Volume:

V = a³ + (1/3)a²h = a³ + (1/3)a²√(l²-(a/2)²)
V = 8³ + (1/3)8²√(10²-4²) = 707.5 cm³

Surface area of pyramid:

A = a² + 2al = 8² + 2*8*10 = 224 cm²

Surface area of cube minus bases:

A = 4a² = 4(8²) = 256 cm²

Total surface area:

A = 224 + 256 = 480 cm²
