n = 20/3

C. -w = 30

w = -30

D. -2c = 32

c = -16

E. 4h = -11

h = -11/4

Which sentence is NOT a geometric progression?

DIA [1.3K]

<u>c) 3, 6, 9 12</u> is NOT a geometric progression

<h3>Further explanation </h3>

Geometry sequences are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

$\large {\boxed {\bold x_n = ar ^ {n-1}}}$

where:

a is the first term, and

r is the common ratio

So we have to see the series has the same ratio or not

a. $\dfrac{5}{1}=\dfrac{25}{5}=5\to \rm geometric\:progression$

b. $\dfrac{8}{4}=\dfrac{16}{8}=2\to \rm geometric\:progression$

c. $\dfrac{6}{3}\neq \dfrac{9}{6}\to \rm not\:geometric\:progression$

d. $\dfrac{6}{2}=\dfrac{18}{6}=3\to \rm geometric\:progression$

What is 2378/2 into a mixed number

Volgvan

There no way that you can make this a mixed number unless you don't simplify all the way, which goes against the laws of math. I guess a fraction out of the answer would be 1189/1...

On the following number line, two rational numbers are graphed.Represent the two numbers as fractions (or mixed numbers) in lowe

nordsb [41]

The first graphed rational number is at the middle of -2 and -1, thus the number represented is $-1 \frac{1}{2}$

The second graphed number is five out of six places from from 0 to 1, thus the number graphed is $0+ \frac{5}{6} = \frac{5}{6}$

The difference between the two numbers can be represented as
$-1 \frac{1}{2} - \frac{5}{6}$
or
$\frac{5}{6} -(-1 \frac{1}{2} )= \frac{5}{6} +1 \frac{1}{2}$

To find the difference,

$-1 \frac{1}{2} - \frac{5}{6} \\ \\ =-1 \frac{3+5}{6} \\ \\ =-1 \frac{8}{6} =-2 \frac{2}{6} \\ \\ =-2 \frac{1}{3}$

Also,

$\frac{5}{6} +1 \frac{1}{2} \\ \\ =1 \frac{5+3}{6} \\ \\ =1 \frac{8}{6} =2 \frac{2}{6} \\ \\ =2 \frac{1}{6}$
