The size of each repayment should be $1,746.38 if the loan is to be amortized at the end of the term.
Given: Loan amount = $320,000
Annual interest rate = 3%
Tenure = 25 years = 25 × 12 = 300 months
Annuity pay = Monthly payment amount to repay the loan each month
Formula used: The formula to calculate the monthly payment amount (Annuity pay) to repay a loan amount with interest over a period of time is given below.
P = (Pr) / [1 – (1 + r)-n]
where P is the monthly payment,
r is the monthly interest rate (annual interest rate / 12),
n is the total number of payments (number of years × 12), and
P is the principal or the loan amount.
The interest rate of 3% per year is charged on the unpaid balance. So, the monthly interest rate, r is given by;
r = (3 / 100) / 12 = 0.0025 And the total number of payments, n is given by n = 25 × 12 = 300
Substituting the given values of P, r, and n in the formula to calculate the monthly payment amount to repay the loan each month.
320000 = (P * (0.0025 * (1 + 0.0025)^300)) / ((1 + 0.0025)^300 - 1)
320000 = (P * 0.0025 * 1.0025^300) / (1.0025^300 - 1)
(320000 * (1.0025^300 - 1)) / (0.0025 * 1.0025^300) = P
Monthly payment amount to repay the loan each month = $1,746.38

Part C2 - Oxidation with Benedict's Solution Which of the two substances can be oxidized? What is the functional group for that substance? Write a balanced equation for the oxidation reaction with chr
Benedict's solution is commonly used to test for the presence of reducing sugars, such as glucose and fructose. In this test, Benedict's solution is mixed with the substance to be tested and heated. If a reducing sugar is present, it will undergo oxidation and reduce the copper(II) ions in Benedict's solution to copper(I) oxide, which precipitates as a red or orange precipitate.
To determine which of the two substances can be oxidized with Benedict's solution, we need to know the nature of the functional group present in each substance. Without this information, it is difficult to determine the substance's reactivity with Benedict's solution.
However, if we assume that both substances are monosaccharides, such as glucose and fructose, then they both contain an aldehyde functional group (CHO). In this case, both substances can be oxidized by Benedict's solution. The aldehyde group is oxidized to a carboxylic acid, resulting in the reduction of copper(II) ions to copper(I) oxide.
The balanced equation for the oxidation reaction of a monosaccharide with Benedict's solution can be represented as follows:
C₆H₁₂O₆ (monosaccharide) + 2Cu₂+ (Benedict's solution) + 5OH- (Benedict's solution) → Cu₂O (copper(I) oxide, precipitate) + C₆H₁₂O₇ (carboxylic acid) + H₂O
It is important to note that without specific information about the substances involved, this is a generalized explanation assuming they are monosaccharides. The reactivity with Benedict's solution may vary depending on the functional groups present in the actual substances.

In a case whereby the survivors are forced to learn new behaviors in order to adapt to the situation and each other. This is an example of Emergent norm theory.
What is Emergent norm?According to the emerging norm theory, groups of people congregate when a crisis causes them to reassess their preconceived notions of acceptable behavior and come up with new ones.
When a crowd gathers, neither a leader nor any specific norm for crowd conduct exist. Emerging conventions emerged on their own, such as the employment of umbrellas as a symbol of protest and as a defense against police pepper spray. To organize protests, new communication tools including encrypted messaging applications were created.

Write the slope -intercept form of the equation of the line containing the point (5,-8) and parallel to 3x-7y=9
To write the slope-intercept form of the equation of the line containing the point (5, -8) and parallel to 3x - 7y = 9, we need to follow these steps.
Step 1: Find the slope of the given line.3x - 7y = 9 can be rewritten in slope-intercept form y = mx + b as follows:3x - 7y = 9 ⇒ -7y = -3x + 9 ⇒ y = 3/7 x - 9/7.The slope of the given line is 3/7.
Step 2: Determine the slope of the parallel line. A line parallel to a given line has the same slope.The slope of the parallel line is also 3/7.
Step 3: Write the equation of the line in slope-intercept form using the point-slope formula y - y1 = m(x - x1) where (x1, y1) is the given point on the line.
Plugging in the point (5, -8) and the slope 3/7, we get:y - (-8) = 3/7 (x - 5)⇒ y + 8 = 3/7 x - 15/7Multiplying both sides by 7, we get:7y + 56 = 3x - 15 Rearranging, we get:
3x - 7y = 71 Thus, the slope-intercept form of the equation of the line containing the point (5, -8) and parallel to 3x - 7y = 9 is y = 3/7 x - 15/7 or equivalently, 3x - 7y = 15.

the area of the pool was 4x^(2)+3x-10. Given that the depth is 2x-3, what is the wolume of the pool?
The area of a rectangular swimming pool is given by the product of its length and width, while the volume of the pool is the product of the area and its depth.
He area of the pool is given as [tex]4x² + 3x - 10[/tex], while the depth is given as 2x - 3. To find the volume of the pool, we need to multiply the area by the depth. The expression for the area of the pool is: Area[tex]= 4x² + 3x - 10[/tex]Since the length and width of the pool are not given.
We can represent them as follows: Length × Width = 4x² + 3x - 10To find the length and width of the pool, we can factorize the expression for the area: Area
[tex]= 4x² + 3x - 10= (4x - 5)(x + 2)[/tex]

For the given function, find (a) the equation of the secant line through the points where x has the given values and (b) the equation of the tangent line when x has the first value. y=f(x)=x^2+x;x=−4,x=−1
The equation of the tangent line passing through the point (-4, 12) with slope -7: y = -7x - 16.
We are given the function: y = f(x) = x² + x and two values of x:
x₁ = -4 and x₂ = -1.
We are required to find:(a) the equation of the secant line through the points where x has the given values (b) the equation of the tangent line when x has the first value (i.e., x = -4).
a) Equation of secant line passing through points (-4, f(-4)) and (-1, f(-1))
Let's first find the values of y at these two points:
When x = -4,
y = f(-4) = (-4)² + (-4)
= 16 - 4
= 12
When x = -1,
y = f(-1) = (-1)² + (-1)
= 1 - 1
= 0
Therefore, the two points are (-4, 12) and (-1, 0).
Now, we can use the slope formula to find the slope of the secant line through these points:
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - 12) / (-1 - (-4))
= -4
The slope of the secant line is -4.
Let's use the point-slope form of the line to write the equation of the secant line passing through these two points:
y - y₁ = m(x - x₁)
y - 12 = -4(x + 4)
y - 12 = -4x - 16
y = -4x - 4
b) Equation of the tangent line when x = -4
To find the equation of the tangent line when x = -4, we need to find the slope of the tangent line at x = -4 and a point on the tangent line.
Let's first find the slope of the tangent line at x = -4.
To do that, we need to find the derivative of the function:
y = f(x) = x² + x
(dy/dx) = 2x + 1
At x = -4, the slope of the tangent line is:
dy/dx|_(x=-4)
= 2(-4) + 1
= -7
The slope of the tangent line is -7.
To find a point on the tangent line, we need to use the point (-4, f(-4)) = (-4, 12) that we found earlier.
Let's use the point-slope form of the line to find the equation of the tangent line passing through the point (-4, 12) with slope -7:
y - y₁ = m(x - x₁)
y - 12 = -7(x + 4)
y - 12 = -7x - 28
y = -7x - 16
