Find the exact sum of the arithmetic series <br><br> 6+3.8+⋯−29.2
matrenka [14]

Answer:

-197.2

Step-by-step explanation:

Since it is arithmetic series, first find the difference d between the two know series.

3.8 - 6 = - 2.2

d = -2.2

a = 6

Tn = -29.2

Looking for the n term, use the linear method.

Tn = a+( n - 1)d

Substitute all the parameters

-29.2 = 6+( n - 1 ) -2.2

-29.2 = 6 - 2.2n + 2.2

- 29.2 = 8.2 - 2.2n

-29.2 - 8.2 = - 2.2n

-37.4 = -2.2n

n = 37.4/ 2.2

n = 17 terms.

To Find the exact sum of the arithmetic series, use the sum formula below

Sm = n/2( 2a + (n - 1)d)

Sm = 17/2( 2 × 6 + ( 17 - 1 ) -2.2

Sm = 17/2(12 - 35.2)

Sm = 8.5( - 23.2)

Sm = - 197.2

Therefore, the exact sum of the arithmetic series is -197.2

Help find missing segment??
AleksandrR [38]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Let x as the missing segment.

_________________________________

According to the Thales theorem :

\frac{26}{x}  =  \frac{12}{36}  \\

\frac{26}{x}  =  \frac{12}{12 \times 3}  \\

\frac{26}{x}  =  \frac{1}{3}  \\

Inverse both sides

\frac{x}{26}  =  \frac{3}{1}  \\

\frac{x}{26}  = 3 \\

Multiply sides by 26

26 \times  \frac{x}{26}  = 26 \times 3 \\

x = 26 \times 3

x = 78

Thus the missing segment has a measure of 78 .

masya89 [10]

In the given equation the value of the x be a x = U*ky-y.

According to the statement

we have to find that the value of the x from the given statement.

So, For this purpose, we know that the

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

From the given information:

The given statement is

U=x+y/ky

now, rearrange the terms then

U*ky=x+y

U*ky-y = x

And then the value f the x become

x = U*ky-y.

So, In the given equation the value of the x be a x = U*ky-y.
