Answer:
31.40 ft^2
Step-by-step explanation:
You are trying to find the circumference, C = 2 * r * 3.14
1. To get the radius you divide the diameter by 2: 10 / 2 = 5
2. Plug your radius into the equation
C = 2 * 5 * 3.14
3. Your final answer should be 31.40 ft^2

I think it would reflect y less than x as we start x^2 for f(x) and usually 1 or 2 is the answer in quadratics. Once we have found y we can work out x

Answer:
i think its B
Step-by-step explanation:
Given that the printer depreciates at the rate of 14% p.a. This has been modeled by the function V=2400(1-0.14)^t, this follows an exponential form given by
y=a(b)^x
where:
V=y
a=2400
b=1-0.14
x=t
thus:
<span>Part A: Explain what the parameter 2,400 represents in the equation of the function.
</span>The parameter 2400 represents the initial value of the printer at time t=0. This is the original value.
<span>Part B: What is the factor by which the printer depreciates each year?
The factor of depreciation is 14% percent. This is the rate at which the printer depreciates and it accounts for the value of the printer at the end of every year.
</span><span>Part C: Amy also considered purchasing a printer that costs $4,000 and depreciates by 25% each year. Which printer will have more value in 5 years?
Value after 5 years of the $2400 printer that depreciates at 14% per year will be:
V(t)=2400(1-0.14)^5=$1,129.025
Value after 5 years of the $4000 printer that depreciates at 25% per year will be:
F(t)=4000(1-0.25)^t
F(5)=4000(1-0.25)^5=$949.22
The printer that costs $2400 will be more valuable compared to the printer that cost $4000</span>
