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.
Answer:
Step-by-step explanation:
The area of a rectangle can be found with the formula , where
is the length of the rectangle and
is the width.
From the given problem statement, we know that and
, so we can fill in those values in the formula anbd solve for
to get the width:
Divide both sides by to isolate
by itself:
