To find the common and to see whether the sequence is geometric or not you have to divide n+1 term to n term. 

For example 2nd to 1st:
6:2=3
18:6=3

The answer is yes. The sequence is geometric and the common ration is 3. I hope that this is the answer that you were looking for and it has helped you.

Decide whether each number is written in standard notation or scientific notation.
VARVARA [1.3K]

The answers are as follows:

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7  - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

Concept: Standard notation is a way of writing a number so it is easier to read. It is often used for very large or very small numbers.

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

In the given questions,

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7  - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

Find the angle θ, in radians, in the second quadrant whose tangent is -2.
ololo11 [35]

In order to find the angle  θ, in <u>radians</u>,  whose<u> tangent</u> is -2  you have to follow those steps

Step 1

Using a<u> calculator</u>

Find the angle  θ

Angle=arc\ tan(-2)= -63.43\°

Remember that

the angle θ belong to the second quadrant

so

Angle θ=180\°-63.43\°=116.57\°

Step 2

Convert degrees to <u>radians</u>

we know that

\pi\ radians=180\°

116.57\°=116.57\°*\pi/180\°=0.648\pi\ radians

therefore

the answer is

the angle θ is 0.648\pi\ radians
