Answer:
f(n)=-5-3n
Step-by-step explanation:
Given the recursive formula of a sequence
f(1)=−8
f(n)=f(n−1)−3
We are to determine an explicit formula for the sequence.
f(2)=f(2-1)-3
=f(1)-3
=-8-3
f(2)=-11
f(3)=f(3-1)-3
=f(2)-3
=-11-3
f(3)=-14
We write the first few terms of the sequence.
-8, -11, -14, ...
This is an arithmetic sequence where the:
First term, a= -8
Common difference, d=-11-(-8)=-11+8
d=-3
The nth term of an arithmetic sequence is determined using the formula:
T(n)=a+(n-1)d
Substituting the derived values, we have:
T(n)=-8-3(n-1)
=-8-3n+3
T(n)=-5-3n
Therefore, the explicit formula for f(n) can be written as:
f(n)=-5-3n
Answer:
A=2πrh+2πr^2
Step-by-step explanation:
Letter B or π is an irrational number, therefore it's the answer.
So your equation is a composite function. It means to plug 1.5 as x into g(x), then the answer you get for that, plug into h(x).
So.
g(1.5)=8-3(1.5)
=8-4.5
=3.5
Then.
H(3.5)=2x+5
=2(3.5)+5
=7+5=12
Your final answer is 12.
