Step-by-step explanation:

The 6th term of the sequence is -0.081.

What is geometric sequence?

A geometric sequence can be defined as the sequence of numbers where any two consecutive terms have the same ratio. This ratio is called the common ratio of the sequence.

Given that,

The first term of the geometric sequence is, a₁ = -8100.

The common ratio is r = -0.1.

The general expression for the nth term is given as,

aₙ = a₁rⁿ⁻¹

Substitute n = 6 to obtain,

a₆ = -8100 × (-0.1)⁶⁻¹

    = -8100 × (-0.1)⁵

    = -0.081

Hence, the 6th term of the given sequence is -0.081.

Show your work on paper please

Answers

Answer:

1)9984 and 2) 756

Step-by-step explanation:

624

16

6x4=24

add the 2 on top

6x2=12+2=14

add the one on top

6x6=36+1=37

add a zero and now

1x4=4

1x2=2

1x6=6

add them up and you get 9984

Now for the second question

6,048 divided by 8

8 divided by 8=1

8 divided by 2 =2

8 divided by 6=1.3

and I got 756

The answer for the first one is 9,984. The answer for the second one is 756

The Adjacent angle to <LON are <NOP, <NOK and <LOK.

What are adjacent angle?

When two angles share a shared vertex and side, they are said to be neighbouring angles. The vertex of an angle is the terminal of the rays that create the sides of an angle. When two adjacent angles have a common vertex and side, they might be complimentary or supplementary angles.

Now, the adjacent angle to <LON are <NOP, <NOK and <LOK.

Dexter claim is wrong because <MON is not adjacent to <LON, <MON is just a part of <LON.

and, the part of an angle cannot be considered as Adjacent angle.
