Find the sum of the first 9 terms in the following geometric series. 64+32+16+

Dafna11 [192]

Answer:

The sum of the first 9 terms in the geometric series is 127.75

Step-by-step explanation:

In the geometric series, there is a constant ratio between each two consecutive numbers

Examples:

5, 10, 20, 40, 80, ………………………. (×2)

5000, 1000, 200, 40, …………………………(÷5)

General term (nth term) of a Geometric series is

a1 = a, a2 = ar, a3 = ar², a4 = ar³, ..........

$an=ar^{n-1}$ , where

a is the first term

r is the constant ratio between each two consecutive terms

The sum of the first n terms of a Geometric series is calculated by this rule

$Sn=\frac{a(1-r^{n})}{1-r}$

Let us solve the question

∵ The geometric series is 64, 32, 16, .......................

∴ a = 64

∴ r = 32 ÷ 64 = 0.5

→ We need to find the sum of the first 9 terms

∴ n = 9

→ Substitute these values on the formula of the sum above

∴ $S9=\frac{64(1-0.5^{9})}{1-0.5}$

→ use the calculator to find the answer

∴ S9 = 127.75

∴ The sum of the first 9 terms in the geometric series is 127.75

This is for pre calculus, please help

Harlamova29_29 [7]

Answer:

The correct answer is:

$g(x) = x+1$

Step-by-step explanation:

Given that:

$h(x) = f\circ g(x)= \sqrt[3]{x+3}$

$f(x) = \sqrt[3]{x+2}$

To find:

$g(x) = ?$

Solution:

Let $g(x) = m$

We have

$f\circ g(x)= \sqrt[3]{x+3}\\OR\\f( g(x))= \sqrt[3]{x+3}$ ...... (1)

Now, we have let:

$g(x) = m\\\therefore f(g(x)) = f(m)$

Putting x = in f(x), we get

$f(x) = \sqrt[3]{x+2}\\\Rightarrow f(m) = \sqrt[3]{m+2}$ ....... (2)

Comparing equation (1) and (2):

$\sqrt[3]{x+3} =\sqrt[3]{m+2}$

Taking cubes both sides:

$x+3=m+2\\\Rightarrow m = x+3-2\\\Rightarrow m = x+1$

$\therefore g(x) = x+1$

Hence,

The correct answer is:

$g(x) = x+1$
