B(n)=1 (-2)^n-1<br> What is the 4th term in the sequence
zzz [600]

Answer:

The fourth term of the sequence B(4) =-8

The sequence is 1,-2,4,-8...

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the sequence

     B(n) = 1(-2)ⁿ⁻¹

Put n=1

    B(1) = 1(-2)¹⁻¹ = 2⁰ =1

Put n=2

   B(2) = 1(-2)²⁻¹ = (-2)¹ =-2

Put n=3

  B(3) =1(-2)³⁻¹ = (-2)² =4

Put n=4

B(4) = 1(-2)⁴⁻¹ =(-2)³ =-8

The sequence

1,-2,4,-8...

Simplify
ivolga24 [154]
The correct answer is:  [A]:  " \frac{8}{729} " .
_________________________________________________________
Explanation:
_________________________________________________________
We are asked to simplify:

                  →    (\frac{2}{9})^3   

_________________________________________________________
Note the following property of exponents:
_________________________________________________________

( \frac{a}{b})^n  =  \frac{(a^n)}{(b^n)} ;  { b \neq0 } . 

_________________________________________________________
As such:

→  ( \frac{2}{9})^3  ;

                 
 =
\frac{2^3}{9^3} = \frac{(2*2*2)}{(9*9*9)} =  \frac{8}{729} .

_____________________________________________________________


The answer is:  
" \frac{8}{729} "  ; 

→  which is:  "Answer choice:  [A]:  " \frac{8}{729} " . 
_____________________________________________________________
Hope this answer—and explanation—is of some help to you.
  Please comment below or otherwise respond to me if you have any questions or if I can be of further assistance.
     Best wishes!

julsineya [31]

Answer:

Step-by-step explanation:

sec (-x)-sin (-x) tan (-x)=cos x

sec(x)-(-sin x)(-tan x)=cos x

1/cos x-sin x(sin x/cos x)=cos x

multiply by cos x

1-sin ²x=cos²x

or 1=sin²x+cos²x

which is true.
