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.
Answer:
The third choice is the one you want
Step-by-step explanation:
The solutions are found where the graphs intersect each other, which is in 3 places. We are only worried about the x values here. It appears that they cross, on the far left, at x = -2, in the middle at x = .5, and on the far right at x = 3.5
Answer:
Option D. The circumference
Step-by-step explanation:
A). Area 'y' of square with side 'x' will be represented by
y = (Side)²
y = x²
Since the degree of this polynomial function is 2, It's a quadratic equation.
B). Area of the circle = πr²
y = π(x)²
Since the degree of this polynomial function is 2, It's a quadratic equation.
C). Volume of a cube = (Side)³
y = x³
Since the degree of this polynomial function is 3, It's not a linear function.
D). Circumference of the circle = 2πr
y = 2π(x)
Since the degree of this polynomial function is 1, it's a linear function.
