1. The unpaid balance after 12 months of paying $546.61 for borrowing $81,000 for 27 years at 6.8% is $79,915.29.
2. During this period, the interest she paid was $5,474.61.
How is the unpaid balance determined?The total payment made, including interest and principal, for 12 months is the product of the monthly payments and 12 months.
From the amortization schedule from an online finance calculator at month 12, we can deduce that the loan balance is $79,915.29.
When this balance is subtracted from the loan, the difference is the principal repayment so far.
N (# of periods) = 324 months (27 years x 12)
I/Y (Interest per year) = 6.8%
PV (Present Value) = $81,000
PMT (Periodic Payment) = $-546.61
Results:
Sum of all periodic payments = $-6,559.32 ($546.61 x 12)
Total Interest for six months = $5,474.61
Amortization Schedule:1 $81,000.00 $-546.61 $459.00 $-80,912.39

First place pays $4800 to the winner, second place $3300 and third place $1300. Is it worthwhile to enter the race if it costs $1000?
It is worthwhile to enter the race if it costs $1000.
What is total cost?Total cost is an economic measure that includes not only the initial cash outlay but also the opportunity cost of their choices when producing a product, purchasing an investment, or acquiring a piece of equipment. TVC + TFC = TC
The sum of fixed and variable costs is the total cost. For example, if a company has a fixed cost of $30 per unit and a variable cost of $5 per unit as output increases, the total cost is $35.
In this case, first place pays $4800 to the winner, second place $3300 and third place $1300. It is therefore worthwhile since the amounts are more than $1000.

The unit rate of discovery of the new species of marine animals are; 2000 per year.
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
We have been given about 4000 new species of marine animals were discovered in the last 2 years.
We need to find the unit rate of discovery.
Total = 4000 new species
Time = 2 year.
Unit rate = new species of marine animals/ time period
Unit rate = 4000/ 2
Unit rate = 2000/1

The volume of the cube with the given side length is 1/125b⁹
Calculating the volume of a cubeFrom the question, we are to determine the volume of the given cube.
The volume of a cube is given by
V = s³
Where V is the volume of the cube
and s is the side length of a side of the cube
From the given information,
s = 1/5b³
Thus,
The volume of the cube will be
V = 1/5b³ × 1/5b³ × 1/5b³
V = 1/5 × 1/5 × 1/5 × b³ × b³ × b³
V = 1/125 × b⁹

In math, addition is the process of adding two or more integers together. The terms addends and sum describe the input and output of the addition operation, respectively.
Given the depth on the first day is 232 feet.
Depth on the second day = 193 feet more than on the first day i.e. 193 feet + depth on the first day
This implies, depth on the second day = 193+232

Derivatives:The derivative of a function is a function that indicates how quickly another function is changing. Differentiation is a term used to describe the process of finding a derivative. In an equation, it is shown as the dependent variable with respect to the independent variable. A value's derivative is a change in value relative to its input. The symbol for a derivative is f'(x).
Here we have
d²y/dx²-3(dy/dx) - 4y = 0
As we know (d/dx) = D
=> D²-3D - 4 = 0
=> D²- 4D + D - 4 = 0
=> D(D - 4) + (D - 4) = 0
=> (D - 4) (D + 1) = 0

What is the break-even point?The break-even point is the production and sales point at which the total costs equal the total revenue.
At the break-even point, there is no profit or loss.
Total units produced = x
Let the cost of production = C
Let the revenue = R

Now, we have to use the rule of clockwise 90° rotation, states that to rotate the figure 90 degrees clockwise about a point, every point(x , y) will rotate to (y, -x).
According to this rule, the new coordinates are written as,
A(0,0) = A'(0,0)
B'(-4,3) = B'(-3,-4)

I need help I really don’t get this question
The surface area of prism is 224 square centimeter
The surface area of the prim = 2 × Area of the hexagonal face + 6 × Area of the rectangular face
The area of the hexagonal face = 42 square centimeter
The area of the two hexagonal face = 2×42
= 84 square centimeter
The area of the one rectangular face = length × width
= 4 × 8
= 32 square centimeter
The area of the 6 rectangular face = 6 × 32
= 192 square centimeter
The surface area of the prim = 32 + 192
= 224 square centimeter
Hence, the surface area of prism is 224 square centimeter
