What is the sum of the first five terms of a geometric series with a1 = 6 and r = 1/3? Express your answer as an improper fracti

Likurg_2 [28]

Answer:

242/27

Step-by-step explanation:

Using the formula for the sum, you can fill in the given values and do the arithmetic.

Sn = a1·(r^n -1)/(r -1)

S5 = 6·((1/3)^5 -1)/(1/3 -1) = 6(-242/243)/(-2/3) = 6·(121/81)

S5 = 242/27

_____

Or, you can write the terms and add them up. The sum is ...

6 + 2 + 2/3 + 2/9 + 2/27 = (162 +54 +18 +6 +2)/27 = 242/27

What is the length of the unknown side

KatRina [158]

Answer: ↓↓↓

Step-by-step explanation:

1. a = ? b = 16 c = 18

a² + b² = c²

a² + (16)² = (18)²

a² + 256 = 324

- 256 -256

a² = 68

√a² = √68

a ≈ 8.25

2. a = 4 b = 8 c = ?

a² + b² = c²

(4)² + (8)² = c²

16 + 64 = c²

80 = c²

√c² = √80

c ≈ 8.94

Charlotte is running at a rate of 9\,\dfrac{\text{km}}{\text{h}}9 h km 9, start fraction, start text, k, m, end text, divided

OverLord2011 [107]

Answer:

2.5 meters per second

Step-by-step explanation:

Given,

The speed of Charlotte = 9 km/h

That is, the distance covered in 1 hour = 9 km,

∵ 1 km = 1000 m

So, the distance covered in 1 hour = 9000 m,

∵ 1 hour = 60 minutes and 1 minute = 60 seconds,

⇒ 1 hours = 3600 seconds,

∴ The distance covered in 3600 seconds = 9000 m,

⇒ Distance covered in 1 second = $\frac{9000}{3600}$ = 2.5 m,

Hence, his/her speed = 2.5 meters per second
