Answer:
B
Step-by-step explanation:
The given sequence is a geometric sequence with a common ratio of 3.
<h3>
</h3><h3>
Which type of sequence do we have here?</h3>
A geometric sequence is a sequence where the quotient between any pair of consecutive terms is a constant, called the common ratio.
Here we have the sequence:
3, 9, 27, ...
The quotient between the first two terms is:
9/3 = 3
The quotient between the third and second terms is:
27/9 = 3.
So yes, we conclude that this is a geometric sequence, where the common ratio is 3.

Hello :
<span>If f(x) = x + 8 and h(x) = 3x − 3,
</span><span>g ∘ f = h
</span>g ∘ (f ∘ f ^-1) = h ∘ f ^-1 ( proprety associative)
but ;
(f ∘ f ^-1) = x
g ∘ x = g
g(x) = (h ∘ f ^-1)(x)
calculate : (f ^-1)(x)
f(x) = x +8
x= f(x) - 8
so : (f ^-1)(x) = x - 8
g(x) = (h ∘ f ^-1)(x) = h((f ^-1)(x)) = h(x - 8) = 3(x - 8) -3
g(x) = 3x - 27

two pieces = length of the first piece divided by the length of the second piece is 2.
a. first piece: x
second piece: y
x/y = 2 ∴ x = 2y
b. y = 0 ∴ x = 0
If he divides the rope, we have x and y ≠ 0.
c. x+y = 40
x = 2y
2y + y = 40
3y = 40
y = 40/3
y = 13.3
