Answer:
21
Step-by-step explanation:
Answer:
8*5^n-1 / 2^n-1 = n
This is the function for your sequence
Yes because of you find the gcf for 9 and 15, the answer would be 3 so the asnwer is still odd.
Use the change-of-basis identity,

to write

Use the product-to-sum identity,

to write

Redistribute the factors on the left side as

and simplify to

Now expand the right side:

Simplify and rewrite using the logarithm properties mentioned earlier.





(C)
Answer:
see explanation
Step-by-step explanation:
let x be the amount Kweku gets then Kofi gets 3x , so
x + 3x = 4800
4x = 4800 ( divide both sides by 4 )
x = 1200
that is
Kweku gets $1200
Kofi gets 3 × $1200 = $3600
