Part 1:
The table showing the decreasing debt is shown as follows:
![\begin{tabular} {|c|c|c|c|} Starting Balance&Interest Accrued&Payment&Closing Balance\\[1ex] \$1,853.42&\$22.39&\$400&\$1,475.81\\\$1,475.81&\$17.83&\$400&\$1,093.64\\\$1,093.64&\$13.21&\$200&\$906.85\\\$906.85&\$10.96&\$200&\$717.81\\\$717.81&\$8.67&\$200&\$526.48\\\$526.48&\$6.36&\$200&\$332.84\\\$332.84&\$4.02&\$200&\$136.86\\\$136.86&\$1.65&\$138.51&- \end{tabular}](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%0A%7B%7Cc%7Cc%7Cc%7Cc%7C%7D%0AStarting%20Balance%26Interest%20Accrued%26Payment%26Closing%20Balance%5C%5C%5B1ex%5D%0A%5C%241%2C853.42%26%5C%2422.39%26%5C%24400%26%5C%241%2C475.81%5C%5C%5C%241%2C475.81%26%5C%2417.83%26%5C%24400%26%5C%241%2C093.64%5C%5C%5C%241%2C093.64%26%5C%2413.21%26%5C%24200%26%5C%24906.85%5C%5C%5C%24906.85%26%5C%2410.96%26%5C%24200%26%5C%24717.81%5C%5C%5C%24717.81%26%5C%248.67%26%5C%24200%26%5C%24526.48%5C%5C%5C%24526.48%26%5C%246.36%26%5C%24200%26%5C%24332.84%5C%5C%5C%24332.84%26%5C%244.02%26%5C%24200%26%5C%24136.86%5C%5C%5C%24136.86%26%5C%241.65%26%5C%24138.51%26-%0A%5Cend%7Btabular%7D)
The column for interest accrued is obtained by the folmular
where P is the month's starting balance.
Part 2:
From the table, the last payment is $138.51
Part 3:
The total amount paid by the time the credit card is payed of is the summation of the "payment" column of the table.
Thus, the total amount is given by:
Part 4:
The debt ratio is given by
The answer for this problem is 3.66666666.
Answer:
- π is the area of a circle of radius 1
- π is the circumference of a circle of diameter 1
- π is the constant of proportionality relating the diameter of a circle to its circumference
Step-by-step explanation:
Area of a circle = πr² or πd²/4
Circumference of a circle = 2πr or πd
r is the radius
d is the diameter
If radius = 1
Area = π(1)²
Area = π
hence π is the area of a circle of radius 1 is CORRECT
Given d = 1
Area = πd²/4
Area = π(1)²/4
Area = π/4
Hence π is the area of a circle of diameter 1 is INCORRECT
For the circumference;
C = 2πr or πd
If r =1
C = 2π(1)
C = 2π
Hence π is the circumference of a circle of radius 1 is INCORRECT
Also if d = 1;
C = πd
C = π(1)
C = π
hence π is the circumference of a circle of diameter 1 is CORRECT
Since C = πd, then π is the constant of proportionality relating the diameter of a circle to its circumference is CORRECT
The angle is the last out of 180, so it is 55.
Answer:
Step-by-step explanation:
Given the perimeter of the rectangular garden = 20 meter
Perimeter of a Rectangle = 2(l+w)
Therefore:
2(l+w)=20
l+w=10
l=10-w
Area of the Garden = 18.75 square meters.
Area of a Rectangle = l X w
lw =18.75
Substituting l=10-w derived earlier
(10-w)w =18.75
The equation in terms of w that models the situation is given as:
