Which one is the geometric sequence.

Mathematics
1 answer:
MrMuchimi3 years ago
8 0

Answer:

C

Step-by-step explanation:

A geometric sequence has a common ratio r between consecutive terms

A

4 ÷ 2 = 2

6 ÷ 4 = 1.5

Thus not a geometric sequence

B

1 ÷ 1 = 1

2 ÷ 1 = 2

Thus not a geometric sequence

C

\frac{1}{2} ÷ 1 = \frac{1}{2}

\frac{1}{4} ÷ \frac{1}{2} = \frac{1}{2}

\frac{1}{8} ÷ \frac{1}{4} = \frac{1}{2}

D

4 ÷ 7 = \frac{4}{7}

1  ÷ 4 = \frac{1}{4}

Thus not a geometric sequence

Then the geometric sequence is C

Elimination method. -2y = 0.5 - 2x<br> 6х + Зу = 6
AysviL [449]

Answer:

y=-1.5

X=1.75

Step-by-step explanation:

Yuh arrange the equations in order for easy subtracting of the equations.

-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.

6x+3y=6

3y=-6x+6 then divide both sides by three to get y

y=-2x+2

now arrange

y=-2x+2

y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x

RST is an equilateral triangle; <br><br><br><br> If TX = 6 then RX =
lara31 [8.8K]
In the figure, tx is perpendicular to line RS.this means we can use the pythagorean theorem to determine RX length the long way or simply apply the theorem that each divided triangle becomes a 30-60-90 angle. If opposite to 60 deg is equal to 6 units, then the side's length is equal to 2*6/sq rt 3 or equal to 6.93 units. The answer is half of this equal to 3.47 units.

If a x 10^n is scientific notation, then a must be between 1 and
Yanka [14]

Answer:

  A)  10

Step-by-step explanation:

In the US, a number in scientific notation will have a mantissa (a) such that ...

  1 ≤ a < 10

That is, the value of "a" must be between 1 and 10 (not including 10).

_____

<em>Comment on alternatives</em>

In other places or in particular applications (some computer programming languages), the standard form of the number may be a×10^n with ...

  0.1 ≤ a < 1

In engineering use, the form of the number is often chosen so that "n" is a multiple of 3, and "a" is in the range ...

  1 ≤ a < 1000

This makes it easier to identify and use the appropriate standard SI prefix: nano-, micro-, milli-, kilo-, mega-, giga-, and so on.
