Classify each sequence as arithmetic, geometric, or neither by dragging it into the correct box.
garik1379 [7]

The sequences are classified, respectively, as:

Geometric, Arithmetic, Neither.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

In the first sequence, we have that:

q = \frac{45}{15} = \frac{15}{5} = \frac{5}{\frac{5}{3}} = \frac{\frac{5}{3}}{\frac{5}{9}} = 3

Hence it is a geometric sequence.

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

In the second sequence, we have that:

d = -4 - 1 = 1 - 6 = 6 - 11 = 11 - 16 = -5

Hence it is an arithmetic sequence.

<h3>What about the third sequence?</h3>

\frac{4}{3} \neq \frac{3}{2}, 1 - \frac{1}{2} \neq 2 - 1

Hence it is neither arithmetic nor geometric.

The system of equations is graphed in the figure.
Scilla [17]

Answer:  The correct answer is:  [C]:

___________________________________________

              →    " ( 3, -2) " .

___________________________________________

Explanation:

___________________________________________

By looking at the graph {provided) of the lines of the 2 (two) equations given, we see that the two (2) lines intersect at the point at which the coordinates are:   " (3, -2)" ;  that is:  where:  " x = 3;  y = - 2 " ;  (refer to "image attached");

  →  which corresponds to:

 

  →  Answer choice:  [C]: " (3, -2) " .

___________________________________________

Let us check our answer, by plugging in "3" for "x" ; and "-2" for "y" ;

  in Each of the 2 (two) equations given; to see if the equations hold true:

_____________________________________

Equation 1:

_____________________________________

  y = (-5/3)x  + 3  ;

 →  -2  =? (-5/3)*3  + 3 ?  

 →  -2  =?  -5  + 3 ? ;    -2 =? -2 ?  Yes!

_____________________________________

Equation 2:

_____________________________________

 y = (1/3)x -3 ;

→  -2 =? (1/3)*3  - 3 ? ;

→  -2 =?  1 - 3 ?  ;    -2 = ? -2 ?  Yes!

_____________________________________

Both equations hold true when:  "x = 3 ;  and y = -2 " .

_____________________________________

Refer to image attached to see where the lines of the graphs of the equations given intersect.

_____________________________________

Hope this answer is helpful to you!

  WIshing you the best!

-2.777777777repeating as a fraction
saul85 [17]
Any repeated fraction is written as the number devided by nine(s).
for example
0.1111... =1/9
0.23232323... = 23/99

so the given number= -2 -7/9 = -25/9

The area of a trapezium shaped field is 480m the distance between two parlel sides is 15m and one of the parrellel side is 20m f
Annette [7]

The other parallel side is 44 m

Step-by-step explanation:

Let us revise the formula of the area of a trapezium

A=\frac{1}{2}(b_{1}+b_{2})h , where

  • b_{1} and b_{2} are its parallel bases
  • h is its height (The distance between the two parallel bases)

∵ The area of a trapezium is shaped field is 480 m²

∴ A = 480 m²

∵ The distance between two parallel sides is 15 m

∴ h = 15 m

∵ One of the parallel side is 20 m

∴ b_{1} = 20 m

We need to find b_{2}

Substitute all these value in the rule of the area below

∵ A=\frac{1}{2}(b_{1}+b_{2})h

∴ 480=\frac{1}{2}(20+b_{2})(15)

- Multiply the two sides by 2

∴ 960=(20+b_{2})(15)

- Divide both sides by 15

∴ 64=20+b_{2}

- Subtract 20 from both sides

∴ 44=b_{2}

The other parallel side is 44 m
