First, find the fraction of the circumference represented by central angle 7pi/8:
7pi/8
--------
2pi
Then find the circumference; it is C = 2 pi r, or 2pi(6), or 12 pi units
Then the arc length is 7pi/8 7
-------- * 12 pi = -------- units, or 21/4 units, or 5 1/4 units.
2pi 16 pi

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>
Best Answer: <span> w1•d1 = w2•d2
150•`15 = 300 d2
2250 = 300 d2
d2 = 2250 ÷ 300 = 7.5 ft </span>
Answer:
Let's find out!
Step-by-step explanation:
So we have to set up an equation
Let x= # of ribbons that can be cut
Thus:
So, we cannot have 36/7 ribbons! It's not possible!
So we just simplify!
There we go! She can cut 5 ribbons off!
I'll let you figure out the last one!
Hope this helps!
P.S. Stay Safe!
