2+8+32+128…..,n=9 Evaluate each geometric series described

Mathematics
1 answer:
DedPeter [7]2 years ago
6 0

The value of 2+8+32+128…..,n=9 is 174762

<h3>How to evaluate the series?</h3>

The series is given as:

2+8+32+128…..,n=9

Start by calculating the common ratio (r)

r = 8/2

r = 4

The sum of the series is then calculated as:

S_n = \frac{a *(r^n - 1)}{r -1}

This gives

S_9 = \frac{2 *(4^9 - 1)}{4 -1}

Evaluate the difference

S_9 = \frac{2 *( 262143)}{3}

Evaluate the quotient

S_9 = 174762

Hence, the value of 2+8+32+128…..,n=9 is 174762

Help with this algebra question
Degger [83]
We have:
 3x + 4y = 12
 The first thing we should do in this case is clear and.
 We have then:
 4y = -3x + 12
 y = (- 3x + 12) / (4)
 Rewriting:
 y = (- 3/4) x + 3
 We evaluate now for x = 4
 y = (- 3/4) (4) + 3
 y = -3 + 3
 y = 0
 The ordered pair is:
 (x, y) = (4, 0)
 Answer:
 
y = (- 3/4) x + 3
 
(x, y) = (4, 0)

A tourist purchases a car in england and ships it home to the united states. the car sticker advertised that the car's fuel cons
Valentin [98]

<u>Solution-</u>

Fuel consumption rate = 40 miles per UK gallon (As the car is manufactured in UK)

1 UK gallon = 4.5459631 lit

1 US gallon = 3.7853060 lit

\therefore \frac{1 \ UK \ gallon}{1 \ US \ gallon} = \frac{4.5459631}{3.7853060} = 1.2009499

\Rightarrow 1 \ UK \ gallon = 1.2009499 \ US \ gallon

As the fuel consumption rate = 40 miles per gallon

⇒ You need 1 UK gallon of fuel to go 40 miles

⇒ You need 1.2009499 US gallon of fuel to go 40 miles

Or you can say that, to go 40 miles you need 1.2009499 US gallon of fuel

⇒ To go 1 mile you will need  \frac{1.2009499}{40} = 0.0300237

⇒ To go 738 miles you will need 0.0300237×738 = 22.1574906 US gallon of fuel

∴ 22.1574906 gallon of fuel is actually required.

∴ But, what she thinks will require is \frac{738}{40} = 18.45 gallons (As she calculated using UK gallons)

Hey!

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

Points:

(-2, 3) and (3, 0)

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

Find the slope:

= \frac{y2 - y1}{x2 - x1} \\=\frac{0 - 3}{3 - (-2)}\\= \frac{-3}{5} or -0.8

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

Slope Intercept Form:

y = mx + b

m = slope

b = y-intercept

Slope = -3/5

Y-intercept = 9/5

Answer: y = -3/5 + 9/5

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

Point Slope Form:

y - y1 = m(x - x1)

You can use either of the points.

Answer:

y - 3 = -3/5(x - 2)

          or

y - 0 = -3/5(x - 3)

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

Hope This Helped! Good Luck!
