Answer:

\displaystyle -16 < x

Step-by-step explanation:

\displaystyle -4[\frac{x}{-4}] < 4[-4] → x > -16

Whenever you divide\multiply by a negative, you reverse the inequality symbol.

** The above answer is written in reverse, which is the exact same result.

≥, ≤ → Solid Circle [●]

>, < → Blank Circle [○]

6.2×10 +6×10³ Brainiest if right
wel

Answer: 6062

<u>Add Parentheses</u>

(6.2*10)+(6*10^3)

Note: Always Multiply the Parentheses first!

<u>Multiply</u>

6.2*10=62

6*10^3=6000

<u>How is 6×10^3 6000?</u>

Before you multiply the whole equation you first Multiply 10 3 times. This is called an Exponent. In my own words, an exponent is a number that tells you how many times to multiply that number. So if we had 6^2 I will multiply 6×6 2 times. So we multiply 10×10×10 and get 1000. Then we multiply 6×1000 and get 6000.

<u>Add</u>

Since the final step is to add we Add the answer we got for 6.2×10 and 6×10^3.

Therefore we are adding 62*6000 and we get 6062.

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

<u>Examples:</u>

5,  10,  20,  40,  80,  ………………………. (×2)

5000,  1000,  200,  40,  …………………………(÷5)

General term (nth term) of a Geometric series is

<em>a1</em> = <em>a</em>, <em>a2</em> = <em>ar</em>, <em>a3</em> = <em>ar</em>²,  <em>a4</em> = <em>ar</em>³, ..........

an=ar^{n-1}, where

<em>a </em>is the first term

r is the constant ratio between each two consecutive terms

The sum of the first <em>n</em> 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, .......................

∴ <em>a </em>= 64

∴ <em>r </em>= 32 ÷ 64 = 0.5

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

∴ <em>n</em> = 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

∴ <em>S</em>9 = 127.75

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