Answer:
C = 78.54
A = 490.87
Step-by-step explanation:
1. Circumference Formula
C = 2πr (r=d/2=12.5)
C = 2π12.5
C ≈ 78.54
In terms of pi:
25π
2. Area of circle
A = πr^2
A = π12.5^2
A ≈ 490.87
In terms of pi
156.25π or 625π/4

Answers
Answer:
Surface area = 80 cm²
Step-by-step explanation:
Surface Area of rectangular prism = 2(LW + LH + WH)
L = 4 cm
W = 4 cm
H = 3 cm
Plug in the values
Surface Area = 2(4*4 + 4*3 + 4*3) = 2(16 + 12 + 12)
Surface Area = 2(40) = 80 cm²

Step by step:-
Jace purchases a new motorcycle for $8000. The bike depreciates 12% every year.
Write two equations that models the price of the bike after 5 years.
Answers
Answer:
We know that the original price of the bike was $8,000.
After one year, the price of the bike decays a 12%, then the new price of the bike is:
P(1) = $8,000*( 1 - 12%/100%) = $8,000*(1 - 0.12)
After another year, the price again decays a 12%, the new price will be:
P(2) = $8,000*(1 - 0.12)*(1 - 12%/100%) = $8,000*(1 - 0.12)*(1 - 0.12) = $8,000*(1 - 0.12)^2
We already can see the pattern here, after t years, the price of the bike will be:
P(t) = $8,000*(1 - 0.12)^t
With this equation, we can find the price of the bike after 5 years, where we only need to replace t by 5
We will get:
P(5) = $8,000*(1 - 0.12)^5 = $4,221.9
The price of the bike after 5 years is $4,221.9.
Now we want two equations to represent this, so we need another.
This is kinda trivial, because there is only one equation that represents this, so we only can rewrite our equation in another form.
We could say that the price of the bike after t years is:
P(t) = $8,000*(0.88)^t
or something like:
P(t) = $7040*(0.88)^(t - 1)
Where i multiplied the initial value by 0.88, and then reduced the exponent by one.
Use a linear approximation (or differentials) to estimate the given number. (Round your answer to two decimal places.) (1.999)3
Answers
Consider the function f(x) = x ³. Since 2³ = 8 is a perfect cube that is pretty close to x = 1.999, take the linear approximation to f(x) at x = 2. It is
f(x) ≈ L(x) = f (2) + f ' (2) (x - 2)
Compute the derivative:
f(x) = x ³ → f ' (x) = 3x ² → f ' (2) = 12
Then
L(x) = 8 + 12 (x - 2) = 12x - 16
Now approximate 1.999³ :
f (1.999) ≈ L (1.999) = 12•1.999 - 16 = 7.988
(Compare this to the actual value, 7.98801.)

Vincent Pancozzi borrowed $750 on a one-year simple interest loan at 17% interest. The monthly payments were $63.57. Find the amount of interest, amount applied to the principal, and the new balance for the first monthly payment.
Answers
Answer:
Amount of interest = 127.5
Amount applied to main = 877.5
New balance for the first monthly payment = 813.93
Step-by-step explanation:
Since Vincent Pancozzi borrowed $ 750 on a one-year simple interest loan at 17% interest and the monthly payments were $ 63.57, to find the amount of interest, amount applied to the principal, and the new balance for the first monthly payment the following calculations must be made:
Amount of interest: 750 x 0.17 = 127.5
Amount applied to main: 750 + 127.5 = 877.5
New balance for the first monthly payment: 877.5 - 63.57 = 813.93

Total Per Unit Total Per Unit
Cost A 500 0.2 1000 0.2
Cost B 2000 5 2000 2.5
Cost C 750 3.2 1000 2.4
Cost D 100 0.5 250 0.3
A. Cost A
B. Cost B
C. Cost C
D. Cost D
Answers
Answer:
The answer is "Option A and Option B"
Step-by-step explanation:
In question 1:
The fixed cost=2621.21
The unit variable cost=35.58
Calculating the total cost for 45 boat slips:
[tex]=2621.21+(45 \times 35.58)\\\\=2621.21+(1601.1)\\\\=4222.31 \approx 4222[/tex]
In question 2:
It is the pure fixed costs that remain consistent in total regardless of dynamic loads. An overall cost B both for 1000 and 2000 unit is unchanged, therefore the Cost B is a fixed sum.

According to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library. If 1004 people was polled, about how many were in favor of the expansion?
Answers
Answer:
Some 224 people were in favor of the expansion.
Step-by-step explanation:
Given that, according to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library, if 1004 people was polled, to determine how many were in favor of the expansion should be done the following calculation:
1/4 = 0.25
100 = 1004
22.25 = X
1004 x 22.25 / 100 = X
223.39 = X
Thus, some 224 people were in favor of the expansion.
