3.1.1 How can you tell the difference between the debits and the credits in this bank statement?
3.1.2 List any two fixed debits and any two flexible debits for the month
3.1.3 Look at the balance column to work out the value of A, the opening balance before her salary was paid in
3.1.1
Answer:
Debits and credits are used to monitor incoming and outgoing money in your business account. In a simple system, a debit is money going out of the account, whereas a credit is money coming in. However, most businesses use a double-entry system for accounting. This can confuse inexperienced business owners, who see the same funds used as a credit in one area but a debit in the other.
Double-Entry Accounting
When you look at your business finances, there are two sides to every transaction. This means that the rent is one account with a balance due and the business checking is another account that pays the balance due. So the same money is flowing but is accounting for two items. The double-entry system creates a chart of accounts. These include items such as rent, vendors, utilities, payroll, and loans.
3.1.2
Fixed Debit or Fixed debt:
A fixed debt or installment loan is generally one in which a borrower makes regular payments, where the debt has a beginning date, an end date, a fixed interest rate, and a fixed monthly fee (most installment loans are paid monthly). In other words, they adhere to a set amortization schedule. The interest on these type of loans are generally not tax deductible like mortgage loans and therefore are considered consumer debt. While many fixed-rate mortgages are fixed debts we have separated them since fixed debts outside of mortgages are considered consumer debt.
Types of fixed debts:
Automobile loansLoans on Recreation Vehicles, Boats, Motorcycles, etc.Furniture loans (if set payment, not on a credit card)Appliance loansDebt Consolidation loansStudent LoansFlexible Debit Card :
The flexible Debit card is highly favorable and the most popular transaction account. With the Flexi Debit card linked to several Postbank Savings and Investment Products, the Flexi Debit card offers you Transactional flexibility and freedom.
One can deposit your salary into the account and withdraw the money as and when needed. You can also use it for shopping instead of carrying cash.

Find the area of the shaded region 10cm and 85 degrees. Help please!
The area of the shaded region is equal to 425π / 18 square centimeters.
How to determine the area of a circular sectionThe picture indicates us that we must find the area of the shaded region, consisting in a circular section with a measure of central angle of 85° and a radius of 10 centimeters. The area (A), in square centimeters, can be found by using the following formula:
A = (α / 360) · π · r²
Where:
α - Measure of the central angle, in degrees.r - Radius of the circular section, in centimeters.If we know that α = 85° and r = 10 cm, then the area of the shaded region is:
A = (85 / 360) · π · 10²
A = 425π / 18 cm²

Let us consider the small triangle to be ABC and the larger triangle to be ADE
where angle A is the common angle of both the triangle
By triangle proportionality theorem,
If a line parallel to one side of a triangle intersects the other two sides, the two sides are proportionally divided.
Thus line BC is parallel to DE and hence divides AB and AD as well as
AC and AE proportionally
Thus Triangle ABC is Similar to triangle ADE by SAS
Thus,
AB/BD=BC/DE=AC/CE
Thus, using AB/BD=AC/CE

5) Imagine that a family just secured a loan for their new home with the following terms:
Loan amount: $160,000 Interest rate: 7% Length of loan: 30 years
Regular Monthly payments: $1064.48 (that is “R” already calculated for you!)
The wife, a sharp former MATH 170 student, suggests that if they make payments of HALF their regular monthly payments every two weeks (instead of a full payment once per month), they would pay off the loan much more quickly and save A LOT of money overall. Find the total amount they would save if they did this.
Hints (follow these steps): Find the half payment (one half of R that’s given!!). If payments are every two weeks, what is n (how many two weeks periods are there in one year?). Use those terms (new R and n) and solve for time. Now find total payments in this case (Rnt), and compare to original loan’s total payments.

Solution:
Let f(x) = (x+3)^(1/3).
First, we have
lim_(x → -3) f(x) = (-3+3)^(1/3) = 0 = f(-3)
So f(x) is continuous at a = -3.
Next we have
lim_(h → 0) [f(-3+h) - f(-3)] / h
= lim_(h → 0) h^(1/3) / h
= lim_(h → 0) 1 / h^(2/3)
= infty
Since the limit does not exist, f(x) is not differentiable at a = -3.

The balance owed on your credit card triples from $800 to $2400 in 9 months. If the balance is growing linearly then it would take 34.9 months to reach $7000. If, on the other hand, the balance is growing exponentially, f(x)=800(1+0.13)x where x represents the number of months, what would the balance be after 34.9 months? Round your answer to the nearest cent.
The balance owed on the credit card if the growth is exponential according to the equation is; $57,528.
What is the balance owed on the credit card if the growth was exponential as opposed to linear?It follows from the task content that the initial amount owed was; $800.
On this simple note, since the equation given in the task content for the exponential growth from above is;
f(x)=800(1+0.13)^x
So therefore, when x = 34.9 months; we then have;
f(x)=800(1+0.13)^34.9
f(x) = 800(1.13)^34.9
f(x) = 800 × 71.19
f(x) = $57,528

The equation of the line passing through points (-3,0) and (0,3) is y=x+3.
The equation of the line passing through two points (x₁,y₁) and (x₂,y₂) can be calculated using the formula y-y₁=m(x-x₁) , where m denotes the slope of the line .
from the given graph we can find that the line passes through the two points (-3,0) and (0,3)
we get the values , as x₁=-3 , x₂=0 and y₁=0 , y₂=3 .
Slope of the line can be calculated by using the formula ,
m=(y₂-y₁)/(x₂-x₁)
Substituting the values we get ,
m = (3-0)/(0+3)
m=3/3 = 1
Now substituting the values of x₁, x₂, y₁, y₂ and m in the formula of equation of line we get ,
y-0=1(x-(-3))

Amir drove from Jerusalem to the lowest place on Earth, the Dead Sea.
His altitude relative to sea level (in meters) as a function of time (in minutes) is graphed.
What was Amir's altitude at the beginning of the drive?
The equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is: y=-12x+360.
What is Straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point.
First of all let's write the slope-intercept form of the equation of a line, which is:
y=mx+b
where m is the slope and b is y intercept.
So we just need to find m and b to solve this problem.
Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:
m=-12
Negative slope because Amir is descending. So:
y=-12x+b
To find b, we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point (30,0
). Therefore, substituting this point into our equation:
y=-12x+b
0=12(30)+b
0=-360+b
b=360
Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:
y=-12x+360.
Therefore the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is: y=-12x+360.

Answer + Step-by-step explanation:
Consider the equation :
5x² - 20x + k = 0
∆ = b² − 4bc is the discriminant of the quadratic equation.
In our equation :
a = 5 ; b= -20 ; c = k
Then
∆ = (-20)² − 4×5×k

= 20×(20 − k) (Factoring)
The equation 5x² - 20x + k = 0 has exactly one real solution
if and only if ∆ = 0.
Solving the equation ∆ = 0 :
∆ = 0

Answer:
y = 4/3x - 5
Step-by-step explanation:
y-intercept will be (0,-5)
so m = (y2-y1)/(x2-x1)
m = (-5 -7)/(0 - 9) = (-12)/(-9) = 4/3
Using m = 4/3, y = 7, x = 9
y = mx + b
7 = 4/3(9) + b
7 = 12 + b
b = -5
