We need to find the value of .
C stands for combination.
The formula of combination is as follows :
Here,
n = 19 and r = 1
So,
So, the value of is 19.

Answer:
Function for given situation is :
Value of computer after 4 years = $720.3.
Step-by-step explanation:
Given that the value of a $3000 computer decreases about 30% each year. Now we need to write a function for the computers value V(t). then we need to find about how much will the computer be worth in 4 years.
It clearly says that value decreases so that means function represents decay.
For decay we use formula:
where P=initial value = $3000,
r= rate of decrease =30% = 0.30
t= number of years
A=V(t) = future value
so the required function is
or
Now plug t=4 years to get the value of computer after 4 years.
Hence final answer is $720.3.
