Answer:
Step-by-step explanation:
From your characteristic equation, your recursive equation is

the general solution:

The initial conditions are

For f(0) = 1, that is

For f(1) = 3, that is


From (*) and (**) you solve for A and B
you have A = 4/7 and B= 3/7
Replace A, B into the general one, you have the particular solution for the given condition

Answer:
3
Step-by-step explanation:
C 2,4,5 or 8 because 80 is divisible by all of these numbers
Answer:
x=1.88
Step-by-step explanation:
Answer:
25%
Step-by-step explanation:
The formula for finding change over time
P= N-O/O times 100
P= percent
N= new value (for this problem 40)
O= old value (for this problem 32)
100 to get the percentage
First, subtract 32 from 40 to get 8.
Then, divide 8 by 32 to get 0.25
Lastly multiply by 100 to get 25 which is your percentage of change
